YIDACHEM--A construct the most super excellent specialized base of glycol ethers

Propylene glycol monomethyl ether series

●Usage：
With similar physical and chemical character to that of ethyleng glycol ether and even lower toxicity,these products are environment protection-oriented solvents,which is used as solvent,dispersing agent and thinner in such trades as paint,ink,dyeing and printing,pesticide,cellulose and propynoic and ether etc.,and also used as anti-freeze,extractor,beneficiation regent,as well as raw material of organic synthesis.
