Frequently Asked Questions

What is HPMC used for?

HPMC is widely used in construction (tile adhesives, renders, plasters), detergents (thickening agent), pharmaceuticals, and cosmetics due to its excellent water retention, thickening, and film-forming properties.

Is your RDP compatible with cement-based systems?

Yes, our redispersible powder is specifically formulated for cementitious systems, enhancing flexibility, adhesion, and water resistance in tile adhesives, EIFS, and repair mortars.

Do you offer custom formulations?

Yes, our team of application engineers can work with you to develop customized chemical solutions tailored to your specific performance requirements and processing conditions.

How do you ensure product quality?

We maintain a strict quality control system with ISO 9001 certification, advanced lab equipment, and third-party testing. Every batch is tested for viscosity, moisture, ash content, and performance characteristics.

What are your packaging options?

We offer standard packaging in 20–25 kg multi-layer paper bags with PE liner. Custom packaging options are available upon request for bulk orders.
