POSSIBLE APPLICATIONS OF VINNOL® SURFACE COATING RESINS
Since the 1950s, VINNOL® surface coating resins have been found in numerous products. Some of them, such as magnetic tape coatings for video and audio cassettes, have largely disappeared. Others, such as coatings for smartphone casings, have emerged. What has stayed the same is that customers across the globe choose VINNOL® when they are looking for quality and reliability.
We will give you some examples here. At the same time, we invite you to talk to us about your applications and ideas.
What Role Do VINNOL® Surface Coating Resins Play in the Manufacture of Decorative Film?
VINNOL® surface coating resins can be used in a variety of ways to make decorative film.
- Take, for example, complex packaging film, where the film is first produced with its associated decorative surface and hot-stamping is then used to apply this film to the backing material beneath.
- Our resins can also be used to make printed packaging film. Plastic film – including metallized varieties – can be coated with printing ink based on VINNOL® binders, for example. An instance of this kind of coating is gravure printing.
What’s impressive about VINNOL® is its excellent dispersing effect on a wide range of colored pigments, and its outstanding adhesion to substrates, especially polar plastic surfaces.
VINNOL® surface coating resins have stood the test of time not only thanks to their technical precision and reliable processing, but also because they are considered harmless when used as intended, which makes them ideal as binders for sensitive applications.
Hot stamping foils
Knowledge is more than a collection of data or the processing of information. It comes from ideas, intuition, questions and dialog. The last 60 years with our VINNOL® customers have taught us that. That’s why we offer more than just data sheets. You can always talk to our experts about how to order, the right product choice and processing. For example, you can discuss how you can develop and manufacture hot stamping foils to give book covers and other everyday objects an attractive appearance.
What Role Do VINNOL® Surface Coating Resins Play in the Manufacture of Hot Stamping Foils?
In the manufacture of hot stamping foils, VINNOL® surface coating resins can be used in two different types of layers:
- First, in the decorative layers, which ensure the flawless transfer of the intended design from the foil to the substrate under the influence of heat and pressure. Hydroxy and carboxy VINNOL® grades are used here, in particular.
- Second, in the so-called adhesive layer, which bonds the decorative layers to the respective carrier under the influence of temperature and pressure.
In general, VINNOL® surface coating resins are known for their broad versatility, even in sensitive applications, and their excellent interaction with organic and metallic pigments, resulting in brilliant colors. That’s why we often encounter VINNOL® surface coating resins in everyday life: in intricately designed packaging, high-end holographic foil for trademark protection and in the manufacture of high-quality book covers, for example.
Finding the cure for a disease – this must be a moment of true joy in the life of a scientist. It is almost as fulfilling to be able to make the lives of sick people somewhat easier and safer. For example, by developing the perfect blister pack with just the right amount of protection and usability. We are grateful that we can contribute to this with VINNOL®, because it allows us to be a part of the type of progress that can help provide a better quality of life.
What Role Do VINNOL® Surface Coating Resins Play in the Manufacture of Blister Packs?
Aluminum foils provide unbeatable barrier properties, so they are often used as packaging for sensitive medicinal drugs or foodstuffs. To bond aluminum to plastic films in a tack-free manner, aluminum or metallized plastic substrates are frequently given a heat-sealable coating based on VINNOL® binders.
Here, VINNOL® surface coating resins stand out due to the following properties:
- Excellent adhesion to the surface to be coated and to the sealing counterpart
- No known harmful effects as per food regulations
- Odorless and tasteless
- High resistance to chemicals (such as fat, oil, water, acids and bases)
- Blocking resistance
Finishing of artificial leather
Can you remember a time when the journey itself was just as important as the destination? When products were meant to last a lifetime and not just a season? We can. Our business activities have always been geared toward the long term or, as they say today, sustainable.
In product development as well as in our customer relations. Maybe that’s why VINNOL® is still so successful after 60 years, for example in the finishing of artificial leather for handbags, fashion accessories or automotive interior trims.
What Role Do VINNOL® Surface Coating Resins Play in the Finishing of Artificial Leather?
VINNOL® surface coating resins are ideal for finishing artificial-leather surfaces – enhancing not only their feel and luster, but also their chemical resistance.
Depending on your individual formulation, you can use VINNOL® resins as binders in coatings for synthetic leather to increase or decrease a leather article’s luster.
Some types of artificial leather allow you to apply a subsequent VINNOL®-resin-based coating that effectively reduces the undesirable migration of plasticizers to the surface of the leather, thus preventing the material from becoming brittle. This makes it possible for the feel of the surface to remain unchanged for a long period of time and for the artificial leather to withstand mechanical stress. What is more, the leather’s resistance to media such as oils and greases can be enhanced, as can its printability.
Innovative people find it difficult to sit still. They have to explore the unknown to see what’s beyond the horizon. People who literally do this are in luck – they can count on navigation systems, the casings of which are often coated with VINNOL® surface coating resins. But what if new markets are the target? Or a new formulation? Then you need a good partner by your side. Here, you can count on us. We also like to tread new paths and, after 60 years of research, have many a shortcut to show you.
What Role Do VINNOL® Surface Coating Resins Play in the Manufacture of Navigation Devices?
In plastic-casing coatings, VINNOL®
resins adhere particularly well to polar surfaces such as polycarbonate, ABS or other technical thermoplastics. Furthermore, a variety of attractive designs are possible as a result of outstanding interaction with numerous pigments. When a metallic pigmentation is desired for plastics, for example for navigation systems or other electronic devices, carboxyl-functional VINNOL®
grades are used on account of their excellent adhesion to metal surfaces.
Security-relevant printing processes
Surprises are wonderful – but not always. In business, for example, predictability is indispensable. That’s why special security-relevant printing processes with binders such as VINNOL® are used for credit cards. And that’s why we manufacture VINNOL® surface coating resins according to the highest quality standards. This ensures consistent product properties and smooth production processes – predictability. If, in addition, you need something new, we are there for you, too. As a reliable partner, open to surprising new applications.
What Role Do VINNOL® Surface Coating Resins Play in the Printing of Credit Cards?
Modern card systems like credit cards usually consist of several layers of plastic film, which are bonded together using processes such as lamination or high-frequency sealing. For printing processes on the inner layers, the printing inks’ binder composition must ensure:
- Adhesion to the respective surfaces
- Good dispersion of the colorants such that the bonding processes do not cause discoloration or adversely affect the color
The portfolio of combinable VINNOL®
surface coating resins makes it possible to blend non-functional and functional binders in such a way as to enable targeted control of the wetting of pigment surfaces and adhesion to a variety of film surfaces.
Hot stamping on leather
In many cultures, bridal shoes are a symbol of good fortune. In Germany, for example, people used to believe that a marriage would be long and prosperous if young girls collect pennies to pay for their bridal shoes. While this custom may be considered old-fashioned nowadays, the idea behind it is not. We, at least, believe that long partnerships with customers, employees and partners are of lasting value. We are all the more delighted that VINNOL® finds use as a binder in glamorous footwear such as bridal shoes, too.
What Role Do VINNOL® Surface Coating Resins Play in Silver Cinderella Shoes?
VINNOL® surface coating resins display excellent interaction with pigments on both synthetic and real leather. So, appliques such as shiny decorations can be hot stamped onto leather shoes with the aid of VINNOL® resins.
Pad printing on plastic
A golf ball is not simply a small ball. It is a one-, two- or multi-layer structure of rubber, resin and other materials. Even the little dimples are precision work – they determine the flight range, rotation, spin and rolling properties. At the same time, they pose a design challenge: golf balls are often pad printed. Here, VINNOL® surface coating resins can help disperse the pigment in the printing ink and ensure optimum adhesion to the plastic surface. For the perfect ball – and the perfect drive.
What Role Do VINNOL® Surface Coating Resins Play in the Printing of Golf Balls?
VINNOL® binders can be used in the pad printing of golf balls. VINNOL® E grades produced by emulsion polymerization are particularly well suited to this task. They stand out thanks to their excellent pigment wetting and short dispersing times – two factors that positively influence the formulation of printing ink. The adhesion of the printing ink to the plastic surface of the balls can also be enhanced with the aid of special VINNOL® grades.
Protective aluminum films
For thousands of years, alchemists searched for the philosopher’s stone, in order to artificially produce gold. They discovered ether, ammonia and porcelain, for example – but not the secret of gold. Today, at least, it is possible to manufacture deceptively real gold foils – by applying yellow-colored, transparent coatings to aluminum foil. The secret? VINNOL® resins. They facilitate homogeneous dispersion of the yellow pigments and good adhesion to the metal substrate.
What Role Does VINNOL® Play in Protective Films on Champagne Bottles?
The capsule on the cork of a champagne bottle usually consists of aluminum, aluminum composites or plastics printed with metallic color. For these types of applications, pigmented surface coatings based on VINNOL® are ideal.
Here, VINNOL® stands out due to:
- Good adhesion to aluminum and polar plastics
- Good dispersion of color and metallic pigments
- Resistance to alcohol
- Suitability for heat sealing the cap and neck
