Water Based Anti-Scale Compound 1 Pint (500ml)

ATP-641 is an anti scale coating manufactured in the USA to minimize scaling and pitting in heat treatment of steels. This coating is water based and is able to be used on both oil quenching and air quenching steels. It has a working range of 1000F (537C) to 2300F (1260C)

Description

A water-based, ceramic coating formulated to protect
stainless, low alloy, & carbon grade steels against oxide
scale, oxidation, and decarburization
Performance Characteristics
• effective temp. range 1000-2300⁰ F (538-1260⁰ C)
• reduces surface defects such as forged or rolled-in scale
• reduces secondary finishing operations
• spalls on cooling to leave oxide scale-free surface
• demonstrates exceptional green strength upon proper drying to withstand cracking, chipping, peeling, etc.
• excellent paintability; formulated for brushing application (can be adjusted for dipping or spraying by diluting with water – do not thin coating too much)
• desirable heat retention properties for improved hot working operations

Recommendations for Use
• thoroughly suspend and mix before use
• metal surfaces must be free of dirt, oil, grease, metal oxides, and other materials
• coating thickness depends on the time and temperature of exposure (generally, the higher the temperature and longer exposure, the thicker the coating should be applied)
• a wet film thickness of 6 ± 3 mils should be optimal
• ensure bottom coat is thoroughly dried when applying multiple coats
• water-based coatings need ample time to completely dry before entering furnace (can be applied over preheated substrate to accelerate drying time)
