What role does redispersible polymer powder(RDP) play in putty powder?
Mar. 11, 2024
The role of redispersible polymer powder(RDP) in putty powder: it has strong adhesion and mechanical properties, outstanding waterproofness, permeability, excellent alkali resistance and abrasion resistance, and can improve water retention and increase Opening hours, enhanced durability.
Shandong Kundu Chemical Co.,Ltd produces KD 6033N/KD 6044N/KD 6031H Redispersible polymer powder(RDP) has outstanding waterproof properties and good bonding strength. It can also increase the elasticity of the mortar and have a longer opening time. It also gives the mortar excellent alkali resistance and can improve the adhesion/stickiness of the mortar. In addition to its adhesion, flexural strength, wear resistance and workability, it also has strong flexibility among flexible anti-cracking mortars.
1. Effect on fresh mortar
(1) Improve constructionability.
(2) Increase water retention and improve cement hydration.
(3) Increase workability.
(4) Avoid early cracking.
2. Effect on hardened mortar
(1) Reduce the elastic modulus of mortar and increase the matching with the base layer.
(2) Increase flexibility and resist cracking.
(3) Improve resistance to powder falling off.
(4) Hydrophobic or reduced water absorbency.
(5) Increase the adhesion to the base layer.
