Re-dispersible polymer powder

0 Comment

Redispersible polymer powder (short for RDP) is a polymer powder with redispersible property. It is made from synthetic resin emulsion by adding other substances and then dried by spray. So it mainly contains polymer resin, additives, protective colloid, anti – caking agent. The manufacturing processes can be divided into two procedures-The first step is to.. read more →

The Development History of Redispersible Powder   As early as more than 1000 years ago, humans had discovered that the use of natural resin or protein materials can significantly improve the durability of inorganic adhesive materials. For example, Zhaozhou Bridge in China is a good case. This experience has continued into the modern era, especially.. read more →

Basic Concept of Redispersible Powder

0 Comment

Basic Concept of Redispersible Powder   The Redispersible Powder is the main additive of dry powder ready-mixed mortar such as cement-based or gypsum-based. The Redispersible Powder is a polymer of vinyl acetate and ethyl ester which is spray-dried and gathered from the original 2μm to form spherical particles of 80-100μm. Since the surface of these.. read more →
