DescriptionPPG Sigmatherm 500 is a heat resistant modified alkyd aluminium paint. PRINCIPAL CHARACTERISTICSTo be used for the internal and external protection of steel surfacesHeat-resistant up to 500°C (930°F); a minimum of 200°C (390°F) is necessary to fuse the aluminum coatingA minimum drying time of 3 days at 20°C (68°F) should be allowed before exposure to heatApplication by spray improves the appearance of COLOR AND GLOSS LEVEL.RECOMMENDED SUBSTRATE CONDITIONS AND TEMPERATURESSubstrate conditionsSteel; blast cleaned to ISO-Sa2½ or ISO-Sa3, blasting profile 40 – 70 µm (1.6 – 2.8 mils) Substrate temperature and application conditions Substrate temperature during application should be at least 3°C (5°F) above dew point.INSTRUCTIONS FOR USE • Stir well before use • The temperature of the paint should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity • Adding too much thinner results in reduced sag resistance • Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434).Contact us at Morven Industrial Ltd to place an order for PPG Sigmatherm 500.
