Polyoxymethylene Dimethyl Ethers PDM Clean Paint Matching Diluent


Product Description


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; The middle part of the molecule of PDM is polyformaldehyde with low degree of polymerization, and both ends are capped by methyl. General formaldehyde, paraformaldehyde and triaformaldehyde provide polyformaldehyde with low degree of polymerization, while methanol, methylal and dimethyl ether provide the capped methyl group, which is condensed on acid catalyst. 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 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.
