Soudal Silirub 2

Overview

Silirub 2 is a high quality, elastic one-component joint sealant based on silicone. It is very easy to apply, has excellent UV resistance, neutral curing and excellent moisture resistance, low modulus, very good adhesion on many materials and very good resistance to ageing, remaining permanently elastic after curing. It is not paintable and not suitable for natural stone, and is MEKO-free. Used for all usual building joints with high movement, glazing and joint works, expansion joints between many different construction materials, and sealing between uPVC, treated wooden and metal profiles and glass.
