Description:

Wall putty, also known as putty coating, is a kind of substrate used for wall repair and leveling inside architectural decorative materials, which is used to hide or eliminate the imperfections or defects of the surface of the wall substrate, so that it has a smooth appearance, which is divided into internal wall putty powder and external wall putty powder, oily putty and water-based putty. It is generally composed of white cement heavy calcium ash calcium powder and high-performance additives.

High-performance additives include our cellulose ethers (HPMC, MHEC, HEC) and redispersing emulsion powders (RDP/VAE). Our HPMC, HEMC, HEC, RDP products ensure smooth construction of putty, even at different ambient temperatures.

The role of HPMC, HEMC, HEC, RDP in wall putty:

(HPMC, HEMC, HEC) in the wall putty role:

Improve water retention, flow resistance, crack resistance and thickening effect.

Improve the bond strength: a network structure is formed in the putty powder, which increases the bonding area between the putty powder and the substrate surface, thereby improving the bond strength.

Enhance water resistance: It can effectively improve the water resistance of the putty powder, so that the putty layer is not easy to bubble and fall off in a humid environment.

Extend the opening time: with good water retention performance, can extend the opening time of putty powder, convenient construction operation.

Improve hydrophobicity: Improve the hydrophobicity of the wall putty/finish layer, and significantly improve the waterproof effect

Improve construction performance: it can increase the viscosity of putty powder, reduce the dust generated during construction, and improve the construction quality.

Improve stability: An important key to adjusting the proper concentration of fresh mortar. The proper concentration can make the fresh plaster adhere to the wall well, and make its surface smooth, easy to work with no sticky feeling.

Redispersible emulsion powder (RDP) in the wall putty action:

Improve adhesion and mechanical properties: redispersible emulsion powder can be quickly redispersed into emulsion after contact with water, and has the same properties as the initial emulsion. This means that it forms a film that is flexible, weather-resistant and has good adhesion to a variety of substrates.

Increase bending strength: Improve its bending strength to make it more durable.

Improve water resistance and permeability resistance: improve the waterproof performance of the putty and protect the putty from damage caused by moisture.

Improve construction performance: improve the fluidity of putty and make construction smoother.

Increase opening time: help to maintain the wet state of the putty and extend the construction time.

HPMC, HEC, MHEC and RDP are one of the largest application areas for wall putty/putty coatings, and we have developed products of different grades and different properties to meet all customer needs. We can also offer custom formulations that can provide you with the most suitable raw materials and products for your specific local requirements.
