Polyoxymethylene Dimethyl Ethers PDM Clean Paint Matching Diluent
Product Description
PDM, Polyoxymethylene Dimethyl Ethers(Dioxydimethyl Ether Acetate), is ia clean, low thin slow dry solvent, low smell, can be used in clean paint or matching dilutions; has good solubility, and the composition is very stable, this product belongs to the weak polar oxygen solvent, with other types of solvent and resin materials have good mixed use.The position resistance between molecules is low, has a unique high escape coefficient, so as to provide ultra-high stability to the paint film film stage, is conducive to gas overflow, especially in the late film volatilization fast enough, the formation of continuous and stable coating performance, is conducive to the self-leveling of wet film, improve product gloss, prevent foaming.
PDM belongs to weak polar oxygen-containing solvent, which is good with other solvents and resin materials. Good mixed usability, the steric hindrance between molecules is low, and it has a unique high escape system. So as to provide ultra-high stability for the film forming stage of the paint film, which is conducive to the overflow of gas out, especially in the late stage of film formation, volatilization is fast enough to form continuous and stable coating performance, including conducive to self-leveling of wet film, improve product glossiness and prevent foaming.
