VINNACEL® 871
VINNACEL® 871 is a multi-purpose dispersible polymer powder for dry mix mortars, specifically suited for tile adhesives.
It is based on a flexible terpolymer of vinylacetate, ethylene and vinychloride and belongs to the product class VINNACEL® which means that it has a neutral effect on rheology and provides extended open time and very high adhesion after water immersion and heat storage, giving a high degree of formulation freedom. VINNACEL® 871 is part of our standard range, offering you the best-in-class solution for a wide variety of applications.
Properties
• VINNACEL® 871 is a dispersible terpolymer powder composed of vinyl acetate, vinyl chloride and ethylene.
• Dry-mix mortars modified with VINNACEL® 871 exhibit improved adhesion, flexural strength, deformability and
abrasion resistance.
• VINNACEL® 871 is particularly suited for modifying cementitious and gypsum-based dry-mix mortars, especially
tile adhesives.
• VINNACEL® 871 contains a fine mineral filler as an antiblocking agent. It is produced without the use of organic
solvents, plasticizers and film-forming agents.
• VINNACEL® 871 is suitable for formulating high-quality, low-emissions flexible tile adhesives. It provides long open
time and very good tensile adhesion strength, especially after immersion in water and heat aging.

Processing
For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNACEL® 871
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.

Storage
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.
