GENERAL PROPERTIES

ВП4888 Is a copolymer based on vinyl acetate and vinyl versatate. It is obtained by drying with spraying a latex dispersion. It can be easily redispersed in water. The special nature of the polymer provides film formation at low temperatures.
ВП4888 is used to modify mixtures containing hydraulic binders. Due to its special chemical-physical properties, it increases adhesion to the bases, increases the “open time” of solutions. Due to the improved performance of mixtures containing ВП4888, water consumption is reduced.

APPLICATION

Tile Adhesives
ВП4888 is especially recommended for the production of dry building mixes, such as adhesives for tiles with high resistance to slipping. By adding ВП4888 to the finished mixture, even in small quantities, adhesion and thermal stability can be improved. In order for there to be enough adhesive for a tile of small thickness, we recommend adding from 1% to 4% of the product ВП4888 in dry mortar.

Thermal insulation mortars
Adding ВП4888 to mortars ensures good performance of the final product, as well as excellent adhesion and water resistance. For the preparation of adhesives for thermal insulation and mortars for finishing, we recommend adding from 2 to 5% ВП4888.
Repair mortar
Solutions containing ВП4888 have good adhesion and workability; this is why ВП4888 is recommended for repair mortars, mainly due to its special rheological behavior

PACKING

ВП4888comes in 25 kg paper bags and 500 kg big bags.

STORAGE CONDITIONS

ВП4888 must be stored in a cool, dry place. Do not stack pallets on top of each other due to the thermoplasticity of the polymer. After use, the packaging must be well closed to prevent moisture from entering the product from the atmosphere. It can lead to lumps.
