Coloured silicone

Silirub is a low modulus neutral cure elastic silicone. It contains a powerful anti-fungal agent to restrict the growth of mould. It’s virtually odourless and has a very fast skinning time and final cure. It’s thick bodied for ease of use and is solvent free – which means no shrinkage during curing. It also offers primerless adhesion on all standard construction materials, including glass, metals, wood, plastics and masonry substrates. It’s flexible and resistant to rain, snow, many chemicals and temperature fluctuations.

We can colour match any RAL colour based on a minimum quantity of only 60 tubes.
