2 PAINT vs COATING synthetic resin or inorganic silicate polymer. resistant to harsh environmentssuperior performance (adhesion, toughness, and resistance to chemicals, UV, etc.)drying oils and/or natural resinsoxidation/evaporation to form a weather resistant filmcontinues to oxidize and breaking down.
4 Solvents Dissolve film former Reduce viscosity for ease of application Control rate of cureLow molecular weight organic chemicalsExamples include aliphatic, aromatic, and chlorinated hydrocarbons; alcohols; ketones; esters; glycol ethers; and water.
