PPG - Sigmadur ClearCoat is a two component, aliphatic clear acrylic polyurethane gloss finish, suitable for application over aluminium pigmented polyurethanes.

• Excellent gloss retention
• Tough and abrasion resistant
• Resistant to splash of mineral and vegetable oils, white spirit, paraffins, aliphatic petroleum products and mild chemicals
• Reduced sensitivity to early condensation and rain
• Can be recoated even after long atmospheric exposure
• Cures at temperatures down to -5°C
• Suitable for use on stainless, non ferrous materials not subject to immersion

Recommended Substrate Conditions and Temperatures

Atmospheric exposure conditions

• Previous coat (polyurethane) must be dry and free from any contamination.
• Stainless steel, non-ferrous metal should be sufficiently roughened by light sanding follwed by degreased with solvent or cleaner.

Substrate temperature and application conditions

• Substrate temperature during application at -5°C(23°F) is acceptable; provided the substrate is free from ice and dry.
• Substrate temperature during application and curing down to -5°C(23°F) is acceptable
• Relative humidity during application and curing should not exceed 85%

Instructions For Use

Mixing ratio by volume: base to ardener 85:15

• The temperature of the mixed base and hardener should be above 10°C(50°F), otherwise extra thinner may be required to obtain application viscosity.
• Adding too much thinner results in reduced sag resistance and slower cure
• Thinner should be added after mixing the components.
