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. |
