Product Description

SigmaTherm 540 is a one component heat resistant moisture curing silicone coating that produces a slick aluminium finish designed for protecting surfaces at extreme temperatures.

Best Uses

SigmaTherm 540 can be used internally or externally in heavy industrial or construction environments and works to provide the ultimate protection to surfaces that could potentially suffer from heat damage. When used externally SigmaTherm 540 provides top resistance against weathering and offers a degree of UV light resistance with an aluminium finish.
