Frequently Asked Questions

What is the shelf life of your Redispersible Polymer Powders?

Our RPP products have a shelf life of 12 months when stored in a cool, dry place away from direct sunlight and moisture.

Can HPMC be used in gypsum-based formulations?

Yes, HPMC is commonly used in gypsum plasters to improve workability, water retention, and adhesion. Our standard HPMC grades are compatible with gypsum systems.

Do you offer custom formulations?

Yes, our technical team can develop customized additive packages based on specific performance requirements, raw materials, and application conditions.

What packaging options are available?

We offer 20-25kg multi-wall paper bags with inner plastic liners. Custom packaging is available upon request for large volume orders.

How do silicone hydrophobic agents work in mortar?

Silicone-based hydrophobic agents reduce water absorption by modifying the pore structure and surface energy of the mortar, improving durability without affecting breathability.
