PyroCoat EX-12 Technical Data Sheet

PyroCoat EX12 is an economical, thermoplastic, synthetic polymer emulsion for fast-air or force-dry applications. PyroCoat EX12 produces a hard, high-gloss finish that provides excellent water and humidity resistance. PyroCoat EX12 contains a coalescing agent that effectively lowers the film forming temperature of the polymer to improve application at standard room temperatures.

PyroCoat EX12 should be stored at temperatures between 40° F and 90° F. The freeze/thaw stability is satisfactory through 5 cycles.

Handling and Use

PyroCoat EX12 should be applied in a well ventilated area. When spray applying, a proper protective mask and safety goggles should be worn. While PyroCoat EX12 is considered non-hazardous, it may cause skin irritation in certain individuals. Gloves should be worn if application is a dipping process.

If PyroCoat EX12 is being applied to a previously painted surface, make sure the surface is clean and dust free. User should verify that bonding compatibility exists before applying.

Clean all equipment immediately following use with warm water and mild detergent. Once the product drys it is impervious to water, most solvents, acids, and alkalis.

Safety and First Aid

PyroCoat EX12 contains a coalescing solvent that will add a small amount of volatile organic carbon to the atmosphere. Make sure you comply with local emission regulations. The product in general contains no hazardous materials. The following procedures should be followed when using the product:

  1. Apply in a well ventilated area. Use proper breathing apparatus when spray applying.
