Redispersible Polymers Powders Ruvin

RuVin VP8838

CHARACTERISTICS

RuVin VP8838 is a powder, a triple copolymer of vinyl and acrylic esters, stabilized with polyvinyl alcohol. It can be easily redispersed in water. The very low Tg of the polymer makes the resin flexible and resilient. The special chemical composition provides very low film-forming temperatures.

APPLICATION

The compositions prepared with the addition of RuVin VP8838 demonstrate high elasticity and the ability to deform. With the addition of RuVin VP8838, adhesion to cement substrates is also improved.

RuVin VP6638

CHARACTERISTICS

RuVin VP6638 – powder a copolymer of vinyl and acrylic esters, stabilized with polyvinyl alcohol. It can be easily redispersed in water. Its special chemical composition ensures low film-forming temperatures and improves adhesion to cement substrates.

APPLICATION

RuVinVP6638 is used to modify mixtures containing hydraulic binders.
RuVin VP6638 is used for the production of tile adhesives. Even a small amount of RuVin VP6638 improves the adhesion and peel strength of glued tiles. The solutions used for tile adhesives based on RuVin VP6638 have very good performance and increased resistance to heat, water, frost and thaws.

RuVin VP5938

CHARACTERISTICS

RuVin VP5938 is a triple copolymer of vinyl and acrylic esters stabilized with polyvinyl alcohol. It can be easily redispersed in water. It can be used to prepare repeated dispersion of medium and high viscosity with high resistance to alkaline environment.
RuVin VP5938, mixed with cement, sand and various special additives

APPLICATION

RuVin VP5938 is used for the manufacture of mortars, which must have good resistance to bending, to deformation, and must be flexible and thixotropic.
Main scopes:
-Adhesives for polystyrene panels (thermal insulation)

RuVin VP4938

CHARACTERISTICS

RuVin VP4938, mixed with cement, sand and various special additives, including casein, is used for the preparation of mortars with high binding ability and slight shrinkage. RuVin VP4938 is most often used as a self-leveling for floors where it is necessary to increase bending resistance (bending strength).

APPLICATION

Mixtures for bulk floors. Add from 1% to 5% RuVin VP4938 to the other components in powder form, add the required amount of water. Control the temperature. It should not be too high so that grains do not form.

RuVin VP4338

CHARACTERISTICS

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.

APPLICATION

Tile Adhesives. RuVin VP4338 is especially recommended for the production of dry building mixes, such as adhesives for tiles with high resistance to slipping. By adding RuVin VP4338 to the finished mixture, even in small quantities,

RuVin VP3238

CHARACTERISTICS

RuVin VP3238 used to modify mixtures containing hydraulic binders, in cases where it is required to obtain a highly thixotropic composition.
Due to its special chemical and physical properties, RuVin VP3238 improves adhesion to the substrates, increases the “open time” and reduces the water content in mixtures.

APPLICATION

RuVin VP3238 Highly recommended for the production of dry building mixes, such as adhesives for tiles with high resistance to slipping. By adding RuVin VP3238 to the finished mixture, even in small quantities, adhesion and thermal stability can be improved.
