Application:
Propylene glycol monomethyl ether: used in coatings: this product is low toxic and has strong solubility. It is widely used as a solvent and coupling agent for inks, paint coatings and water-based coatings, and is suitable for styrene acrylic lotion, acrylic lotion and its latex paint systems. It has the characteristics of reducing the film forming temperature, promoting its coagulation and film formation, and ensuring that the film has a good state.
Use in pesticides: mainly used as the intermediate of weed killer metolachlor and suspension agent of pesticide lotion.
Other uses: It has multiple applications in fuel antifreeze, cleaning agents, extractants, non-ferrous metal beneficiation agents, etc. It can also be used as a raw material for organic synthesis, a solvent for printing and dyeing, textile dyes, and textile oil agents;
Dipropylene glycol monomethyl ether: used as a stabilizer for PVC, solvent for nitrocellulose, ethyl cellulose, polyvinyl acetate, etc., solvent for coatings and dyes, and also a component of brake oil.
Used as a solvent for printing ink and enamel, as well as a solvent for cleaning cutting oil and working oil.
Used as a coupling agent for water-based dilution coatings (often mixed); Active solvents for water-based coatings; Household and industrial cleaning agents, grease and paint removers, metal cleaners, solvents and coupling agents for hard surface cleaners; Basic solvents and coupling agents for solvent based screen printing inks; Coupling agents and solvents for dye reducing fabrics; Coupling agents and skincare agents for cosmetic formulations; Stabilizers for agricultural insecticides; The setting agent for ground brightening agents.
