Carboxylated SBR Latex Package
- Plastic drum of 50KG/200KG and IBC Tank.
- The shelf life is 6 months.
- Handle with care when transporting. No upside down.
Storage and Instructions
- Store in a cool and dry place at 5-35ËšC and away from direct sun.
- If the SBR temperature is below 6˚C, don’t stir until heated gradually.
- If the SBR is frozen, use after heated gradually and thawed.
- Avoid contact with polyvalent ions, or emulsion breaking will happen.
- Avoid mixing with cationic auxiliary agents, or the stability will be affected.


Safety Precautions
- Pay attention to safety precautions in the MSDS
- Avoid direct contact with eyes and skin.

FAQ About RT9691 Carboxylated SBR Latex
Carboxylated SBR latex contains carboxyl functional groups, having better adhesion, filler compatibility and film-forming property than ordinary SBR latex.
RT9691 Carboxylated SBR latex is for paper related coatings. For other water-based coating systems, it can also be evaluated. Please contact our team, we will provide professional technical details based on your system.
We provide after-sales service as long as the products are within the validity. However, we will provide help and solutions if the period is reasonable.
Start with a lab trial on paper, art paper, or cardboard, then compare gloss, printability, and filler tolerance with your current binder.
It is generally stable in alkaline systems, but very low pH or sudden pH shifts may affect emulsion stability.
Possibly slightly. Film formation may slow drying somewhat, but it can also support coating uniformity and surface strength.
Yes. It can improve wet pick strength by enhancing pigment binding and coating strength in coated paper systems.
