Redispersible Polymer Powder’s Functions:
Increase mortar’s impact resistance, durability, and abrasion resistance:

The polymer emulsion is prepared into a mixture that can be used for spray drying by adding different additives, and the addition of protective colloid and anti-blocking agent enables the polymer to form a free flowing powder that can redisperse in water after spray drying.

Choose hydroxypropyl methylcellulose based on characteristic of Substrate

redispersible polymer powder products are water-soluble re-dispersible powder, divided into ethylene/vinyl acetate copolymer, ethylene acetate/tertiary carbonate copolymer, acrylic acid copolymer, etc., the powder adhesive made after spray drying, with polyvinyl alcohol as the protective colloid.

Main usage of HPMC| Hydroxypropyl Methylcellulose

In building materials, Hydroxypropyl Methylcellulose is mainly applied in the following aspects.

The most valuable method to test the quality of RDP is to add it in dry mixed mortar, to see the behavior of dry mixed mortar in 28 days and years. But there is quick method to feel the quality of RDP.

The greater the viscosity of cellulose ether is, the better the water retention property will be.

Redispersible polymer powder is produced by high temperature and high pressure, spray drying, and with a variety of activities to enhance powder homopolymerization. It can make mortar obviously increase the bonding ability and its tensile strength, resistance to drop, water thickening and construction performance is good. Water resistant, freeze-thaw resistance, heat-resistant ageing performance is outstanding. Ingredients are simple and easy to use.
