Choosing a sealant isn’t just about “sticking” things together; it’s about Movement Capability and Substrate Compatibility.
- The Curtain Wall Workhorse: Aluminium expands and contracts significantly. The 6050 Weatherproofing Sealant is designed specifically for curtain walls. It offers a Class 50 movement rating, meaning it can handle massive fluctuations without tearing. Available in Black, White, and Grey, it is the standard for modern building envelopes.
- Protecting Natural Beauty: 6060 (Non-Staining) Standard silicones contain plasticizers that can “bleed” into porous stones like marble or granite, leaving permanent oily shadows. Our 6060 is formulated to meet ASTM C1248, the global benchmark for non-staining sealants. If your project involves stone cladding, this is a non-negotiable specification.
- The 100% Silicone Standard: 6800 For high-performance weatherproofing, 6800 provides 100% silicone content. This ensures maximum UV resistance, meaning the seal won’t crack or shrink even after 20 years of direct sun exposure.
Why Neutral Cure?
The STARSIL neutral grades (XH-6300, XH-6600) are essential for the aluminium industry. Unlike XH-881 Acetoxy (which releases acetic acid and can corrode metal), our neutral grades are gentle on aluminium profiles and specialized glass coatings.
