Redispersible latex powder products are water-soluble redispersible powders, which are divided into copolymers of ethylene and vinyl acetate. It uses polyvinyl alcohol as a protective colloid. Because the redispersible latex powder has high binding capacity and unique properties.
Adding redispersible latex powder to the caulk mortar can improve its cohesiveness and flexibility. Cemented mortar, even if applied very thinly, can cope with the base material to be adhered to have very good adhesion. If the unmodified cement mortar is not used for the pretreatment of the base layer, it will usually not bond well, and it is easy to cause a certain degree of shedding.
The addition of redispersible latex powder can improve the adhesion. The saponification resistance of the RDP can control the adhesion of the mortar after contact with water and the wall. The copolymerization of vinyl acetate and other suitable monomers can produce saponification-resistant polymerization Thing. Utilizing the experience of using ethylene as a non-saponifiable comonomer to produce RDP containing ethylene can meet all the requirements of RDP in terms of aging resistance and hydrolysis resistance.
