70 & 75 SERIES

HEAT RESISTANT PAINTS

 LOW TEMPERATURE PAINTS, 250-500 ^OF

 Pruett-Schaffer’s 70-Series paints are silicone alkyd vehicles modified with pure silicone resin for corrosion prevention of ferrous metals in dry, continuous, or cycling temperatures of 250-500 ⁰F. They are available in flat black, white, various grays, brown, and in a zinc rich version for enhanced corrosion protection.

 RECOMMENDATIONS

 70-Series provide good corrosion protection with minimum color shift when applied over ferrous metals exposed to low-to-medium temperatures in normal industrial or household environments. They are used direct-to-metal or over heat resisting primers, dry rapidly without a curing schedule, are easy to apply, but do require good surface preparation for acceptable performance.

 Pruett-Schaffer’s 75-Series paints are formulated with either modified or pure silicone resin vehicles for long term corrosion prevention of ferrous metals exposed to wet or dry temperatures in excess of 500 ⁰F.. Product #75-13173 is our highest performance coating and will withstand thermally induced shock such as rain or steam at continuous or cycling temperatures up to 1200 ⁰F. .#75-9422 is an economical modified silicone that has heat resistance to 1200 F but is NOT thermally shock resistant. They are available in aluminum, gray, and black pigmented versions only.

 RECOMMENDATIONS

 These coatings are used direct-to-metal or over heat resisting primers, are easy to apply, but do require good surface preparation and a curing schedule must be followed for maximum heat resistance. They are used on ovens, furnaces, stacks, exhaust systems, steam pipes, etc.
