3.適用範囲と使用方法
PGME is widely used as a solvent in coatings, inks, and cleaning formulations due to its balanced evaporation rate and solvency power. In paints, it improves flow and leveling while reducing viscosity. The printing industry utilizes it as a carrier solvent for dyes and pigments. PGME serves as a coupling agent in household and industrial cleaners, enhancing the removal of oils and greases. It is also employed in electronic chemicals for photoresist formulations and semiconductor cleaning. The chemical’s low toxicity makes it suitable for consumer products, including personal care formulations where regulated.
4.パッケージと保管
Propylene Glycol Methyl Ether (PGME) is typically packaged in 190kg steel drums または ISO tank containers for bulk transportation. For storage, the product should be kept in a 涼しく乾燥した風通しの良い場所 away from direct sunlight and heat sources. As a regulated chemical, it must be handled and transported in compliance with hazardous material regulations.
