Silirub 2S

Premium Neutral Cure Sanitary Silicone

Silirub 2S is a premium-grade low modulus neutral cure sanitary silicone sealant designed for professional sealing applications in high-humidity environments. Manufactured from 100% silicone, it provides a durable, waterproof and permanently flexible seal with excellent resistance to mould growth, UV exposure and weathering.

The advanced neutral cure formulation offers primerless adhesion to most sanitary and construction materials, including many plastics, making it ideal for applications where traditional acetoxy silicones may not be suitable. Its fast skinning time and rapid cure help improve productivity while delivering a long-lasting, professional finish.

Containing a powerful XS1 fungicide, Silirub 2S is specifically developed for sanitary environments such as bathrooms, kitchens, cold storage facilities and air conditioning installations. A food contact certificate is also available for suitable applications.
