PPG Dimetcote 9 (formerly SigmaZinc 170 and Ameron Sigmazinc 9) is a two component moisture curing zinc (ethyl) silicate primer with a high zinc content, designed to provide a protective coating to structural steel. Once applied, this product dries, to form a grey, flat finish that offers excellent resistance in varying conditions. Complies with the compositional requirements of SSPC Paint 20, Level 1.
PPG Dimetcote 9 works using a galvanic action that works to eliminate sub film corrosion and is suitably used as a system primer in various paint systems based on unsaponifiable binders. Due to its toughness and strong nature, Dimetcote 9 can withstand impact and high levels of abrasion.
PPG Dimetcote 9 allows substrate temperature during application and curing down to -18°C (0°F) is acceptable; provided the substrate is free from ice and dry. Substrate temperature during application up to 55°C (131°F) is acceptable. Substrate temperature during application and curing should be at least 3°C (5°F) above dew point. Relative humidity during curing should be above 50%.
A theoretical coverage rate of 8.4m2 per litre for 75 microns DFT is expected when applied by brush, roller or spray.
PPG Dimetcote 9 (formerly SigmaZinc 170 and SigmaZinc 9) can be used internally or externally in extreme conditions and works to provide a solid anti corrosion protective coating to structural steel in an industrial or construction based environment as well as offering excellent abrasion and impact resistance to protect the surface.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
