When formulating CTA with RPP/RDP, it’s important to consider factors such as water retention capacity, workability time, open time before setting occurs, final set time after application onto the substrate surface, minimum thickness requirements for application onto walls or floors, etc. It’s also important to consider which type of cement should be included in order […]

What Is CTA? Cementitious tile adhesive (CTA) is a type of adhesive used for ceramic tile installations. It typically consists of Portland cement or blended cement, silica sand, fillers, and additives such as redispersible polymer powder (RPP/RDP). CTA provides strong adhesion between tiles and substrate surfaces such as concrete or drywall. It also reduces water […]

VAE redispersible powder-Application of RDP Redispersible Latex Powder Redispersible latex powder application 1. Exterior insulation system: Bonding mortar: to ensure that the cement mortar will strongly bond the wall and the epoxy wallboard. Improve the bonding compressive strength. Surface mortar: to ensure the impact toughness, crack resistance and impact resistance of the system. 2. Tile […]

The application of RDP to mortar is actually a modification of ordinary mortar, also known as polymer modified cement mortar. Through polymer modification, the weaknesses of traditional cement mortar such as brittleness and high modulus of elasticity are improved; giving the cement mortar better flexibility and tensile bond strength to resist or retard the generation of cracks in cement mortar

The polymer emulsion is prepared into a mixture that can be used for spray drying by adding different additives, and the addition of protective colloid and anti-blocking agent enables the polymer to form a free flowing powder that can redisperse in water after spray drying.

Redispersible polymer powder, as one of the most important additives in dry-mixed mortar, has been widely used in the construction field. Its invention and appearance have greatly contributed to the promotion and application of dry-mixed mortar. SLEO shows you the great functions of RDP products.
