VINNACEL® 730 is a good hydrophobic dispersible polymer powder for dry mix mortars, specifically suited for skim coat / wall putty
It is based on a semi flexible copolymer of vinylacetate, ethylene and vinychloride which means that it provides a good hydrophobic effect.
VINNACEL® 730 is part of our customized range, offering the best-in-class solution for a wide variety of applications that needs hydrophobicity.
VINNACEL® 730 is a dispersible polymer powder based on vinyl acetate, ethylene and vinyl chloride.
VINNACEL® 730 is a polymeric binder and also provides an good hydrophobic effect.
It provides good workability, tensile adhesion strength, flexibility and abrasion resistance.
VINNACEL® 730 contains fine mineral filler as an antiblocking agent. It is produced without the use of organic solvents, plasticizers and film-forming agents.
VINNACEL® 730 has no effect on rheological properties and is a hydrophobizing powder in the lower Tg range.
It is suitable for formulating skim coat / wall putty that feature good tensile adhesion strength and hydrophobicity.
For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNACEL® 730 with the other dry ingredients in appropriate equipment. Temperatures should not be allowed to rise excessively during mixing because otherwise the dispersible polymer powder could agglomerate by virtue of its thermoplastic properties. The mortar is prepared for use by adding the recommended amount of water and mixing mechanically or by hand. Since hand mixing generates little shear force, we recommend allowing the fresh mortar to slake for 5 minutes and then stirring it again. This is usually unnecessary where mechanical mixers are employed.
For typical application fields of VINNACEL® 730 refer to the following application table. Please discuss additional applications with your WACKER customer representative. If VINNACEL® 730 is used in applications other than those mentioned, the choice, processing and use of VINNACEL® 730 is the sole responsibility of the purchaser. All legal and other regulations must be complied with. Slight color variations of the dispersible polymer powder may occur without impairing the product's functionality

During storage, protect the product from contact with moisture. Prolonged storage at temperatures above 30 °C, especially in combination with pressure, humidity or exposure to sunlight, may result in blocking. Carefully seal any open containers and store them under suitable conditions. We recommend storing the product in a warehouse that provides cool and dry conditions. Do not store the product for more than six months, starting from the date at which it was received, unless the Certificate of Analysis contains a different date, which would take precedence. If the product is stored longer than recommended, it may still be used but users are advised to verify the properties required for the intended use
