Where Carboxylated SBR Latex is UsedÂ
Due to the special chemical structure, Carboxylated SBR latex has improved performance in many fields. Celotech Ruico supports bespoke solutions based on your application needs.
Carboxylated styrene butadiene latex, used as a chemical admixture, can improve adhesion, flexibility, and crack resistance in cement-based systems. The liquid emulsion can not only enhance bonding strength to concrete and mortar, but also to various substrates. And it can also help you improve water resistance and overall durability.Â
Working as a cementing latex, carboxylated styrene butadiene is a high-performance modifier in oil well cementing systems. The emulsion improves slurry stability, flexibility, and resistance to gas migration. Even under high temperature and pressure conditions, it can improve bonding strength and durability.
Celotech Ruico has designed an advanced grade of carboxylated styrene butadiene copolymer for paper coating. It is designed to improve coating strength and surface smoothness, ensuring good gloss, printability, and pigment binding. You can also get good runnability during high-speed coating processes.
Carboxylated SBR latex is also applied in textiles and carpet areas. For carpet backing, this kind of SBR bonding agent can provide strong tuft bind and dimensional stability. It can improve flexibility and resistance to cracking, keep stable performance during manufacturing, and for family use under high traffic.
Packaging, Storage&Instructions
Celotech Ruico Carboxylated SBR Latex is usually packed in plastic drums of 50KG, 200KG and IBC Tank.
Store Carboxylated SBR Latex in cool and dry areas and keep the temperature around 5 to 35˚C. Avoid direct sunlight. Handle with care when transporting. The latex shelf life is 6 months.
If the SBR latex is below 6°C or frozen, warm it gradually and stir only after thawing. Avoid contact with polyvalent ions or cationic additives, as they may cause emulsion instability or breaking.

Client Review
The carboxylated SBR latex from Celotech Ruico showed very good stability in our paper coating formulation. What we are satisfied with is that the pigment binding is improved and the surface finish is smoother without increasing the viscosity. We have ordered two batches, and the performance is consistent.

FAQ About Carboxylated SBR Latex
Yes, it has good compatibility with PVA and Starch.
Yes, the carboxyl groups (–COOH) can interact with cement hydration products. It helps you improve the bonding strength and flexibility of the cement matrix.
It is generally stable in alkaline systems. But when the pH is very low or has sudden changes, the emulsion stability may have some influence.
Yes, it can. Our carboxylated SBR latex can improve pigment binding and coating strength, improving wet pick resistance in coated paper.
Yes, because of film formation, the carboxylated SBR latex may slightly slow down the drying speed. But this can improve coating uniformity and surface strength.
