SigmaTherm 175 is a heat resistant modified alkyd product that produces an aluminium finish, ideal for use on a variety of metal substrates exposed to a high level of heat.
PPG SigmaTherm 175 is named 175 because it resists heat of up to and including 175 degrees celsius and offers high brilliancy in interior and sheltered exterior applications. SigmaTherm 175 is ideally suited for application to pipes, radiators and low heat engines to aid the protection of the surface and surrounding area.
SigmaTherm 175 should be applied using a spray gun to improve the appearance of the surface but can be applied using brush or roller for touch ups too. SigmaTherm 175 is dry to touch after just 3 hours at low temperatures and can be overcoated in 16-36 hours. Make sure you leave 3 full days for the product to cure at 20 degrees before you expose the surface to heat, this is vital in ensuring the product has adhered to the surface properly and will perform properly.
