Protective coating MS-470C

epoxypolyurethaneurethane

Miller-Stephenson’s Urethane Conformal Coating offers superior toughness and abrasion resistance and excellent protection from humidity and organic solvents. Urethane resins are very hard and resistant to mechanical wear, their hardness is second only to epoxy conformal coatings. However urethanes are much easier to be reworked than an epoxy. Miller-Stephenson’s Urethane Conformal Coating have the following benefits: Superior toughness and abrasion resistance Reworkable and room temperature cure Solvent and discoloration resistant Fluorescent under UV light No cracking or crazing with vibration Polyurethane coatings are available as either aerosol or bulk formulations. Both formulations provide excellent humidity resistance and far greater chemical resistance than Acrylic coatings. These Spray Conformal Coating are Single component Polyurethanes, while easy to apply, enjoy long pot life but sometimes require very lengthy cure cycles to achieve full or optimum cure. The cure cycle can be accelerated by the application of heat typically reducing cure times to less than 4-5 hours at 50% humidity. Cleanliness of the substrate is of extreme importance for the successful application of a conformal coating. Surfaces must be free of moisture, dirt, wax, grease, flux residues and all other contaminants. Contamination under the coating could cause problems that may lead to assembly failures. MS-470C will cover 8.6 square feet at a 2-mil thickness per 14-oz. aerosol can. MS-472C, the bulk liquid version of the product, is available in quarts and gallons for dip, brush, or spray applications and will cover 120 square feet per gallon at a 2-mil thickness.
