As a leading China external clear silicone sealant manufacturer, we understand that external glazing and architectural sealing demand more than just "glue." It requires a chemical formulation capable of withstanding extreme UV radiation, thermal expansion, and hydrostatic pressure.
Our R&D team focuses on Information Gain in the adhesive sector—providing data-driven insights into polymer stability and long-term elasticity. Whether it is a high-rise curtain wall or a residential window installation, our clear silicone solutions offer "invisible protection" with a 25-year lifespan guarantee.

Certified Quality
Located in the heart of China's chemical industrial zones (Shandong & Shanghai), we have direct access to high-purity polydimethylsiloxane (PDMS). This reduces transit costs and ensures the freshest chemical precursors for our clear sealants.
With 26 high-speed filling lines, our factory minimizes human error. Precise volumetric control ensures every 300ml or 590ml cartridge meets international weight and density standards without air pocket contamination.
We don't just manufacture; we innovate. Our laboratories conduct accelerated aging tests (ASTM G154) to simulate 20 years of solar exposure, ensuring our clear sealants remain transparent and non-yellowing.
The primary challenge for an External Clear Silicone Sealant Factory is balancing optical clarity with structural strength. Standard clear sealants often yellow over time due to UV degradation of the cross-linking agent. At Saiqiang, we utilize a proprietary non-yellowing catalyst system that ensures our clear sealant remains 99% transparent even in high-UV regions like the Middle East and Australia.
Curing Mechanism: Our neutral cure external clear silicone releases an alcohol byproduct rather than acetic acid. This makes it safe for sensitive substrates like coated glass, aluminum, and natural stone, preventing the corrosion often seen with cheaper acetoxy alternatives.
Global Compliance: For global enterprises, compliance is not optional. Our products are rigorously tested against REACH and RoHS standards. In Europe, we meet the French A+ VOC emissions standards, ensuring that while the sealant is "external," it poses no risk to indoor air quality through window frames.
Localization Support: We provide localized technical data sheets (TDS) and safety data sheets (SDS) in over 15 languages, assisting our partners in navigating local building codes and environmental regulations seamlessly.
High-transparency sealing for structural glass joints where aesthetics are as vital as wind-load resistance. Our 999 and 998 series are the industry benchmark.
Kitchen and bathroom environments require mold-proof properties. Our antibacterial clear silicone prevents fungal growth in 100% humidity conditions.
From sliding door gaskets to solar panel framing, our sealants provide high thermal conductivity and electrical insulation for industrial-grade applications.
