Reliable Consistency for Sealant Makers
Quartz Powder for Sealant is a general-purpose filler. It is built around the core need for batch-to-batch consistency. Compared to our high-end Sealant Silica Powder, it offers a very cost-effective solution. It uses the same quality ore source from Mount Huangshan. The product goes through crushing, purification, and grading. It has a stable chemical makeup and a controlled particle size. Many customers in building and industrial sealants have confirmed that product is a reliable filler.
Hardness and Workability in Balance
This Quartz Powder for Sealant effectively increases the hardness and compressive strength of sealants. At the same time, it keeps the viscosity at a reasonable level. It also maintains good application properties. Our 25 years of experience have taught us that filler stability directly affects sealant quality. So we test every batch for oil absorption, moisture, and particle size. Every ton of product you receive has the same high quality as the last one.

Suitable for Many Sealant Types
Quartz Powder for Sealant works in many building and sealing materials. In silicone weatherproof sealants, it acts as a skeleton filler. It raises the modulus and movement capability. In polyurethane sealants, it improves thixotropy and sag resistance. In acrylic sealants, it raises cohesive strength without changing elasticity. It is also good for prefabricated building sealants and road joint materials. We can customize the particle size and oil absorption for your needs. The minimum order is 1 ton.
