Curing

Air dry at room temperature for 2 - 4 hours.; No heat cure is required if substrate is ramped slowly at ~200 ºF per hour to the operating temperature.

Safety

All Ceramabind™ products are water-based materials that can be washed from the skin, in the uncured state, with mild soap and warm water.; Prolonged skin contact should be avoided to prevent irritation.; If any material contacts the eyes, flush continuously with water or neutralizing solutions, then consult a physician immediately.

Application and Mixing

Liquid binder-to-powder weight ratios of 4:1 to 1:1 are recommended when formulating adhesives, coatings and pastes.; Powder binder (875) to filler ratio of 1:4 is recommended.; Blend powder slowly into binder until desired viscosity is achieved.; Vacuum degas as required to reduce entrapped air.; Apply the mixture to clean surfaces.; Extremely smooth surfaces are difficult to wet and should be sandblasted, etched, or slightly oxidized wherever possible.; Porous substrates tend to absorb and separate the binder from the powder; these substrates should be pre-coated with the binder only before applying the mixture.
