Application Details

Processing

For the production of ready-mixed dry mortars, such as adhesives and patching compounds, blend VINNAPAS® 8812 T 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.

Properties
  • VINNAPAS® 8812 T is a dispersible polymer powder based on a new generation of terpolymer composed of vinyl acetate, vinyl chloride and ethylene.
  • VINNAPAS® 8812 T is a polymeric binder and is ideal for modifying cementitious and gypsum-based drymix mortars, especially tile adhesives.
  • VINNAPAS® 8812 T provides very good workability and thixotropy of the fresh mortar.
  • Compounds modified with VINNAPAS® 8812 T exhibit improved adhesion, flexural strength, deformability and abrasion resistance. Combinations with cement and gypsum can provide mortars which exhibit non-sag properties.
  • Contains a fine mineral filler as an antiblocking agent. It is produced without the use of organic solvents, plasticizers and film-forming agents.
  • VINNAPAS® 8812 T is a non-slump dispersible polymer powder in the medium Tg range. It is suitable for formulating low emission compounds that must exhibit good non-slump properties.
