Different effects of HPMC, starch ether and RDP on gypsum mortar Hydroxypropyl methylcellulose (HPMC) 1. It is stable to acids and alkalis, and its aqueous solution is very stable in the range of pH=2~12. Caustic soda and lime water do not have much impact on its performance. But alkali can speed up its dissolution. And

The role of RDP in mortar

By |2023-03-06T07:28:35+00:00March 6th, 2023|Product Applications|

1. Improve the compressive strength and flexural strength of mortar. 2. The addition of RDP improves the elongation of the mortar. Thereby improving the impact toughness of the mortar. At the same time, it also gives good stress dispersion effect to the mortar. 3. Improve the bonding performance of mortar. The bonding mechanism is based

How to correctly identify redispersible polymer powder(RDP)?

By |2023-02-09T06:46:09+00:00September 30th, 2022|Company News|

Redispersible polymer powder(RDP) is a water-soluble redispersible powder, which is a polymer of butadiene and vinyl acetate, and uses acrylic emulsion as a maintenance colloid solution. Therefore, RDP is very popular in the construction industry sales market, and the inappropriate use of RDP leads to unsatisfactory actual effects of engineering construction. The use of suitable

The mechanism and role of RDP in tile adhesives

By |2023-02-16T08:17:39+00:00June 6th, 2022|Product Applications|

The mechanism and role of RDP in tile adhesives. The modification of cement mortars by polymers allows the two to obtain complementary action effects. Thus allowing polymer-modified mortars to be used in many special applications. In addition, due to the advantages of dry mortars in terms of quality control, construction operations, storage and environmental protection.

About Re-dispersible Polymer Powder(RDP)

By |2022-05-07T07:24:17+00:00May 7th, 2022|Product Applications|

Re-dispersible Polymer Powder is a powder dispersion produced and processed from modified polymer emulsions. It has good redispersibility. It can be re-emulsified into a stable polymer emulsion even after the addition of water, and its chemical properties are identical to the initial emulsion. Therefore, it makes it possible to produce high quality dry-mixed mortar with.
