Sika Everbuild Sikasil-825 Low Modulus Neutral Cure Silicone Sealant 380ml Dark Anthracite

Summary

Sikasil-825 is a professional-grade, low modulus, neutral cure alkoxy silicone sealant from Sika Everbuild, formulated for large-scale construction, glazing, and weatherproofing applications. Its filled alkoxy curing system delivers extended tool downtime, making it particularly suited to longer joints where workability is critical. Available here in Dark Anthracite (approx. RAL 7016), it blends discreetly with modern window and door framing systems.

Features

• Low modulus, neutral cure alkoxy formulation produces very low odour during application.
• Specially formulated for extended tool downtime, allowing more time to finish longer joints neatly.
• Adheres primerless to a wide range of porous and non-porous substrates including glass, aluminium, and uPVC.
• Excellent adhesion to metals, plastics, painted or unpainted wood, and polycarbonate without priming.
• Outstanding external weathering resistance, maintaining performance over many years of exposure.
• Non-staining on most common construction surfaces.
• Suitable for use in construction and dilation joints where stress does not occur until the sealant is fully cured.
• Conforms to ISO 11600 Class F25LM and G25LM when tested to ISO 9047.
