MMP(Methyl-3-Methoxy Propionate) is a ester-ether based solvent with unique linear structure and propionyl group which will enhance the wetting of filler, pigment ,silver powder in coating. MMP is a cost efficient alternative of EEP (Ethyl 3-Ethoxypropionate) and can greatly decrease the surface tension of coating system which, in turn, will eliminate the potential risk of bubble and pinholes. It can also serve as excellent silicone free defoamer solving the re-coating issue of coating.
