Polyoxymethylene Dimethyl Ethers PDM Clean Paint Matching Diluent
Product Description
PDM, Polyoxymethylene Dimethyl Ethers(Dioxydimethyl Ether Acetate), is used as coating solvent and diesel fuel additive as well. It has greater solubility than arenes, and owns amphipathic property. Thus it can easily dissolve other solvents and resins, highly reducing the unpleasant odor.
PDM is a kind of clean taste environmental protection, low thin slow drying solvent, low smell, can be used for clean taste paint or supporting thinner; With good solubility, and the component is very stable, this product belongs to the weak polar oxygen containing solvent, and other types of solvents and resin materials have good mixed use. The steric resistance between molecules is low, with a unique high fugacity coefficient, so as to the film forming stage, provide ultra-high stability, is conducive to the overflow of gas, especially in the film forming later volatilization fast enough, the formation of continuous stable coating performance, is conducive to wet film self-leveling, 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.
PDM is suitable for PU, PE polyester, polyester polyol, thermoplastic acrylic acid, thermosetting acrylic acid and other systems.
Because the product itself is neutral, it does not contain ammonia and free acid and other components, the water content is extremely low ≤0.05. So it also suitable for special thermal curing+UV curing system, for single UV curing, and the system will have certain oxygen inhibition characteristics.
