Product Description

PPG SigmaTherm 230 is a two component high build heat resistant phenolic epoxy coating designed for use under insulation systems to provide heat protection of up to 230°C.

Best Uses

SigmaTherm 230 is a high performance, heat resistant product that provides protection to a variety of metal substrates. PPG SigmaTherm 230 is ideally suited for application to pipes, radiators and low heat engines to aid the protection of the surface and surrounding area.


Blast clean steel to ISO-Sa2.5 with a blasting profile of 40 - 70 microns. The substrate must be perfectly dry before and during application. Degrease stainless steel with solvents and sweep blast. The temperature of the mixed base and hardener should be above 15°C otherwise extra thinner may be required. Adding to much thinner results in reduced sag resistance. Allow sufficient induction time as per data sheet.

Surface and Environment

SigmaTherm 230 is a high performance product that provides surfaces with a high glossy finish to aid protection and offer a level of decoration with an aluminium effect. SigmaTherm 230 should ideally be used internally to offer heat resistance to appliances of up to 230°C.
