SBR Latex for Better Performance in Cement-Based Waterproofing

SBR Latex for Better Performance in Cement-Based Waterproofing

Waterproofing is one of the most important functions in modern construction.

From concrete structures and foundations to bathrooms, balconies, roofs, and underground structures, cement-based waterproofing materials are widely used to help protect buildings from moisture penetration.

However, the performance of a cement-based waterproofing system depends heavily on its formulation.

Polymer modification is one approach that manufacturers can consider when developing cement-based waterproofing materials.

RF-9608A SBR Latex, developed by Zhejiang Ruico Advanced Materials Co., Ltd., is designed for the modification of cement mortar and can be evaluated in cement-based construction formulations.

RF-9608A is a styrene-butadiene latex copolymer with good chemical stability, excellent dispersibility, and good compatibility with various cements. It is also designed to increase adhesion to most substrates.

These characteristics make it an interesting polymer latex for manufacturers developing cement-based construction products where adhesion and formulation compatibility are important considerations.

According to the technical data, RF-9608A has a typical solid content of 48.0 ± 1%, pH of 7.0–9.0, and viscosity of ≤800 mPa·s. Both Tg and MFFT are listed at 6°C.

For waterproofing manufacturers, the polymer latex should be evaluated together with the complete formulation.

Cement type, polymer dosage, fillers, additives, water ratio, mixing conditions, substrate, curing conditions, and application method can all influence the final performance.

Therefore, laboratory testing is essential before commercial production.

At Zhejiang Ruico, we understand that construction chemical manufacturers are looking for more than a basic raw material.

They need stable products, technical information, application communication, and reliable supply.

RF-9608A is available for evaluation by manufacturers and distributors working with cement-based construction materials.

If your company is developing cement-based waterproofing mortar, polymer-modified mortar, or other cement additive systems, we welcome the opportunity to discuss your formulation requirements.
