Redispersible Polymer Powder
I.Keywords
Redispersible Polymer Powder, VAE, RDP
II.Overview
Redispersible polymer powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/versatate copolymers, acrylic copolymers, etc. The powder adhesive is made after spray drying, with polyvinyl alcohol as the protective colloid. This powder can be quickly redispersed into an emulsion after contact with water. Redispersible polymer powder has high bonding ability and unique properties.
III.Performance characteristics
Dispersible polymer powder plays different roles in coatings, adhesives, paper, textiles, leather and other fields. Especifically, in coatings, dispersible latex powder can be used as the raw material of film formers and thickeners to improve the film-forming and coating properties of coatings; in adhesives, dispersible latex powder can be used as the main component of adhesives to increase the toughness and durability of adhesives; in paper, dispersible latex powder can be used as the raw material of paper coating agents to improve the printing performance and surface properties of paper; in textiles and leather, dispersible latex powder can be used as the raw material of coating agents and softeners to improve the quality and performance of products.
It has extremely outstanding bonding strength, improves the flexibility of mortar and has a long open time, gives mortar excellent alkali resistance, improves the adhesion, flexural strength, waterproofness, plasticity, wear resistance and construction performance of mortar, and has stronger flexibility in flexible anti-cracking mortar.

V.Application fields
As an important raw material, dispersible latex powder is widely used in coatings, adhesives, paper, textiles, leather and other fields. Among them, coatings are the largest application field of dispersible latex powder, which can not only improve the film-forming properties of coatings, but also increase the toughness and durability of coatings. In the field of adhesives, dispersible latex powder can be used as the main component of adhesives to produce various wallpapers, tiles, floors and other building materials. In addition, in the field of textiles and leather, dispersible latex powder can also be used as a raw material for coating agents and softeners to improve the quality and performance of products.

VI.Packaging and storage
It needs to be stored in a cool and dry place. The recommended shelf life is six months. Please use it as early as possible in summer. If it is stored in a hot and humid place, the chance of agglomeration will increase. Please use it up once after opening the bag. Otherwise, the bag mouth needs to be sealed to avoid absorbing moisture from the air. International standard paper-plastic composite square bottom valve bag, 20-25kg/bag.
