Description
Neutral Cure Building Silicone Sealant
Silirub N is a professional-grade low modulus neutral cure silicone sealant designed for glazing, construction and industrial sealing applications. Offering excellent adhesion to most common building materials without the need for a primer, it provides a durable, weatherproof and permanently flexible seal for both internal and external use.
The fast skinning and curing formulation allows for efficient installation while delivering long-term resistance to UV exposure, rain, snow and environmental ageing. Its low modulus properties make it ideal for joints subject to movement, including perimeter joints around windows and doors, expansion joints and general construction sealing.
Available in an extensive range of colours, Silirub N is a versatile solution for glazing contractors, builders and maintenance professionals.
