How does the coating work? Mascoat Industrial2 applies the common physics principles of reflectivity, conduction and emissivity, and absorptance. Its microscopic particle structure (which resembles popcorn-like particles) reflects upwards of 85 % of the radiant heat gain back into the environment in which it originated. Each ceramic particle encapsulates air, thereby offering a slow path of thermal transfer. This high content of entrapped and stagnant air very efficiently blocks thermal transfer. In addition, the coating’s low emissivity allows for low heat flux. The combination of these factors allows for total thermal dissipation across the surface. The unique composition of the coating makes it extremely efficient for its thickness and prevents substrates from gaining heat, making surfaces cooler to the touch.

Surface Preparation: The minimum requirement for carbon steel substrates is a solvent wipe in accordance with SSPC SP 1 followed by power tool cleaning in accordance with SSPC SP 3. Adrasive blasting in accordance with SSPC SP 6 is preferred for longer service life. Surface must be free of all contaminants, both visible and non-visible, prior to coating.

Primers: Primers are recommended for carbon steel substrates. Consult Mascoat for the appropriate type of primer for a given environment. Mascoat is self priming over non-ferrous materials such as stainless steel and aluminum.

Airless Sprayer: An airless sprayer is the best applicator. Sprayer should have capacity of at least 1 gallon per minute with 3,000 PSI. We highly recommend a tip size of .017 (for tight spots) and .019-0.23 (for normal use) along with a reversible nozzle. Remove all strainers and filters from gun and sprayer. Failure to do so will result in filtering of insulation particles. Please consult website or detailed instruction sheet for list of sprayers and application instructions prior to application of Mascoat Industrial2. An SA gun can also be used for areas under 100 ft2. (Call Mascoat for details.) All sprayer requirements can also be accessed at our website along with detailed instructions.

Brushing: Brushing is recommended for small areas or for use as a touchup. Apply first coat thinly. Successive coats will cover surface and build more rapidly. Make sure to allow coating to become dry to touch before starting next application.

Rolling: Not recommended.

Thinning: Thinning may not exceed one quart per five-gallon pail for high-temperature applications. Latex conditioners or water is standard thinning medium.

Mixing: Only mud mixing paddles should be used. Use 1/2 inch drill motor to stir. Make sure drill is set to reverse setting to insure that the paddle will not mar the bucket’s inner wall.

Cleaning: Equipment may be cleaned with soap and water.

Warranty: Five-year specific limited warranty.

All tests were performed to ASTM procedures when applicable. RVE testing performed at independent lab and based on R value equivalency comparison - not ASTM certified. Findings may be different due to applications techniques and environmental conditions. Thermal conductivity is based on equivalency testing.
