China Adhesive 2017: WACKER Presents Hydrophobic Grades of Pyrogenic Silica and a VAE Dispersion for Nozzle Applications

Shanghai, Aug 23, 2017

At this year’s China Adhesive show, WACKER will present two hydrophobic grades of HDK® pyrogenic silica. HDK® H30RY can be chemically incorporated into resin networks and is able to improve the mechanical properties and scratch resistance of adhesives and sealants. HDK® H20RH provides polar systems with extremely stable thickening and thixotropic properties. It can also improve the storage stability of amine hardeners. In addition, WACKER will introduce VINNAPAS® EP 6420, a vinyl acetate-ethylene copolymer (VAE) dispersion that offers outstanding performance for nozzle applications and is suitable for environmentally friendly, high-performance adhesives in paper and packaging applications. Other WACKER product highlights include high-performance GENIOSIL® hybrid polymers for construction and industrial applications. China Adhesive 2017 takes place in Shanghai from August 23 to 25.

HDK® H20RH provides polar systems with extremely stable thickening and thixotropic properties. It can also improve the storage stability of amine hardeners. Its application fields include automotive adhesives, half-shell bonding in wind turbines, and chemical anchors

HDK® H30RY is a hydrophobic, methacrylic-functional silica. Thanks to reactive surface treatment, this product can be chemically incorporated into resin networks, enhancing the mechanical properties and scratch resistance of systems based on vinyl esters, polyesters or acrylates. This yields a broad range of applications – from coatings and adhesives to sealants. Moreover, the properties of dental fillings and nail gels can be optimized with HDK® H30RY.

HDK® H20RH is a high-BET hydrophobic silica that has been treated with alkylsilane. This silicone-fluid-free additive features exceptional rheological activity in polar systems. It also prolongs the shelf life of epoxy resin and hardeners for two-compound adhesives, in particular the storage stability of amine hardeners. Its application fields include automotive adhesives, half-shell bonding in wind turbines, and chemical anchors.

VAE-Bindemittel
WACKER’s lab tests prove that VINNAPAS® EP 6420 offers best-in-class performance for nozzle application, showing excellent running stability without skin formation. It is ideal for the environmentally friendly, high-performance adhesives used in paper and packaging applications

Low-Environmental-Impact VAE Dispersion with Outstanding Performance for Nozzle Application

VINNAPAS® EP 6420 is a new VAE dispersion specifically developed for the formulation of water-based adhesives in demanding paper and packaging applications. This all-purpose VAE binder offers best-in-class performance for nozzle application, showing excellent running stability without skin formation, high setting speed as well as outstanding cleanability. It can also be used for roller application and improves production efficiency. VINNAPAS® EP 6420 makes formulations with a very broad range of viscosities possible. As no external plasticizers are necessary due to the chemical composition of VINNAPAS® EP 6420, it also enables the formulation of adhesives with low migration potential.

GENIOSIL® hybrid polymers not only combine the typical advantages of silicones and polyurethanes, but also offer further benefits. Thanks to WACKER’s unique α-silane modification technology, GENIOSIL® hybrid polymers feature extremely low viscosity, which allows rapid and complete curing without blistering. They can also be formulated without tin or plasticizers according to application needs, and provide the finished product with outstanding storage stability

High-Performance GENIOSIL® Hybrid Polymers for Construction and Industrial Applications

At China Adhesive 2017, WACKER is unveiling new grades of its GENIOSIL® brand to complement its portfolio of silane-terminated polyethers. GENIOSIL® hybrid polymers are silane-curing organic polymers. They not only combine the typical advantages of silicones and polyurethanes, but also offer further benefits. Thanks to WACKER’s unique α-silane modification technology, GENIOSIL® hybrid polymers enable the finished product to be cured rapidly and completely without blistering. They can also be formulated without tin or plasticizers according to application needs, and lend finished products outstanding storage stability. Furthermore, GENIOSIL® hybrid polymers can be blended with each other and thus provide flexibility for customer formulations.

GENIOSIL® hybrid polymers have a comprehensive product line to cover diverse needs in construction and industrial applications. GENIOSIL® STP-E basic polymers are used to formulate a wide range of adhesives and sealants with different modulus and strength. Super-high-strength GENIOSIL® XB is ideal for strong bonding between dissimilar materials, for example, construction-sector structural bonding, free nail glue and tile grouts. GENIOSIL® XT features tear-resistant properties and is suitable for applications that repeatedly undergo high dynamic forces, such as vibrations in trains and white goods. GENIOSIL® XM is suitable for low-modulus sealants widely used in fabric construction, while GENIOSIL® WP is designed for waterproofing applications.
