Redispersible powder, in short RDP, which is also called redispersible powder(RDP) is widely used in the construction field. It can be used in the cement mortar, wall putty, EIFS mortar, inner wall mortar, tile bonding mortar and tile seam filling. The extraordinary bonding ability make it a very outstanding bonding additive in the construction. And also improves the coating and spreading rate of the mortar or putty. Also anti cracking, highly improves the strength for the structures.
Bonding ability checking.
We can make a small amount of RDP solution and pour it onto a tile with clean surface. Then wait until it is totally dried. Then there should be a film of VAE left on the surface, and if it is very hard to scrape off, then it will be qualified. VAE will penetrate into the surfaced of the tile when dried.
Filming and dispersible ability checking.
We make a small amount of RDP solution and pour it into the glass garden and wait until it is dried. It will shall form a smooth and even layer of film. And when we tear it off from the bottom and stretch it. It shall be elastic and tensile.
Here's a video showing the ways of quality check.
