Application:
PM:
Application in coating: PM, low toxic and strong soluble, is widely used as solvent and coupling agent of ink, paint coating and water-based paint. It is suitable for benzene propylene emulsion, propylene alkene acid emulsion and its emulsion paint, which are characterized by reducing the coating temperature, speeding its cohesion and keeping the coating in a good condition.
Application in pesticide: PM is mainly used as intermediate of metolachlor for weedicide, and as suspension agent of pesticide emulsion.
Other applications: PM can be used in anti-freezer of fuel, cleanser, extractor, and ore-dressing agent for non-ferrous metals. In addition, it can be used as material of organic synthesis, dyestuff of dyeing and textile, and solvent of spinning oil.
DPM is used as solvent for PVC stabilizer, nitrocellulose, ethyl cellulose, polyvinyl acetate, solvent for paint and dyestuff, and an ingredient of brake fluid.
It can be used as solvent of printing ink, enamel paint, cutting fluid and operating oil; as coupling agent of water-based paint (usually used by mixing up); as active solvent of water-based paint; as solvent and coupling agent of household and industrial cleanser, remover for grease and paint, cleanser for metal and hard surface; as base solvent and coupling agent of solvent-type silk-screen printing ink; as solvent and coupling agent of vat dye textile; as coupling agent and skin-care agent in cosmetic formula; as stabilizer of pesticide and coagulating agent of floor brightener.
