- Good adhesion on most existing coatings
- Available in MIO or conventional pigmented grade
- Good resistance to splash and spillage of chemicals
- Meets NSF Standard 61 for valves (US manufacturing only)
- Colours: Standard primer colours and custom colours available
- Gloss level: Semi-gloss
Method of Application
- Air spray
- Airless spray
- Brush/Roller
Note:
Epoxy coatings will chalk and fade with exposure to sunlight. Light colors are prone to ambering to some extent. Note that product tinted to custom colors are not recommended for immersion service. Only use factory grind batches for immersion.
Coating performance is proportional to the degree of surface preparation. Remove all loose paint, mill scale, and rust. The surface to be coated must be dimensionally stable, dry, clean and free of grease, oil, and other foreign materials. When proper abrasive blast surface preparation is not practical, surfaces should be chipped clean and wire brushed to bare, clean material.
Application by brush: apply evenly using a clean, well-loaded brush. Application by brush or roller will provide approximately 80 μm (3.1 mils) DFT in a single-coat application.
Please refer to the product Data Sheet for surface preparation, mixing and application instructions.

Please contact us for suitable primers and topcoats for PPG SigmaCover 400.
Note:
A detergent wash with Prep 88 / Sigmarite 88 or equivalent is required prior to application of topcoats after 30 days of exposure.
If maximum recoat time has been exceeded, roughen surfaces.
Alkyd coatings and waterborne acrylic coatings should be applied after the film is dry to handle and not greater than three times dry to handle time.
Maximum recoating time is highly dependent upon actual surface temperature – not simply air temperatures. Sun-exposed or otherwise heated surface will shorten the maximum recoat window.
