High-Performance SBR Latex for Paper Coating Applications – RF-9691 & RF-9692

In modern paper manufacturing, coating technology plays a critical role in determining the final appearance and printing performance of paper products. As the demand for high-quality printing paper, art paper, and coated board continues to grow, paper mills are seeking more reliable binder systems that can deliver consistent surface quality, improved gloss, and stable coating performance.

RF-9691 and RF-9692 styrene-butadiene rubber (SBR) latex are developed specifically for paper coating formulations. These products function as high-performance binders in pigment coating systems, helping paper manufacturers achieve improved coating structure, printing properties, and production stability.

Designed for Paper Coating Systems

RF-9692 is a water-based carboxylated styrene-butadiene copolymer latex developed for coating processes such as blade coating and other high-speed paper coating operations. The product typically features a solid content around 50% and a fine particle size structure, which helps ensure  dispersion and coating uniformity in pigment systems.

This optimized latex structure contributes to the formation of a smooth and uniform coating layer on the paper surface, improving overall paper quality and appearance.

Key Advantages in Coated Paper Production

In pigment coating formulations containing calcium carbonate, kaolin clay, or other mineral fillers, SBR latex acts as the primary binder that connects pigment particles and anchors them to the paper surface. RF-9691 and RF-9692 offer several important benefits for paper manufacturers:

Improved coating gloss
The latex forms a uniform film structure that enhances surface smoothness and gloss, making coated paper more suitable for high-quality printing applications.

Enhanced printing performance
A well-balanced binder system helps optimize ink absorption and ink holdout, producing sharper print images and improved color density.

Good pigment compatibility
The latex demonstrates strong compatibility with common paper coating pigments such as ground calcium carbonate (GCC) and kaolin clay, ensuring formulation stability and consistent coating results.

Stable coating processability
The controlled viscosity and dispersion stability contribute to smoother coating operations and better runnability on high-speed coating machines.

Suitable for Various Paper Grades

RF-9691 and RF-9692 SBR latex products are widely used in different coated paper applications, including:

• Art paper and coated printing paper

• Coated paperboard and packaging board

• Base coating and pre-coating formulations

• High-speed blade coating systems

By improving binder performance within the coating layer, these latex products help paper manufacturers achieve better surface quality, stronger coating structure, and more reliable printing performance.

Reliable Binder Solutions for Modern Paper Coating

As coated paper markets continue to demand higher visual quality and printing consistency, selecting the right binder system becomes increasingly important. RF-9691 and RF-9692 SBR latex provide a balanced combination of coating performance, formulation compatibility, and production stability, making them suitable binder solutions for modern paper coating technologies.
