Application of 4-Methoxyphenol

Hydroquinone monomethyl ether is a high-efficiency polymerization prevention for unsaturated polyester resin, methyl methacrylate, acrylonitrile, plastic acetate, and so on; a stabilizer for high polymers such as polyvinyl chloride and also polymethacrylic acid. It can likewise be utilized as an antioxidant as well as a pharmaceutical intermediate, and can be utilized as a whitening representative, decolorizing agent, as well as infrared Z absorber when made right into an ointment. Its application examples are as adheres to:

The finishing is made from rosin epoxy acrylic material (made by (meth)acrylic acid, rosin glycidyl ester as well as rosin glycidyl ester via esterification response), isophorone diisocyanate, 4 Ethylene diacrylate (weakened solution), hydroquinone monomethyl ether (polymerization inhibitor), 2-hydroxyethyl acrylate, pentaerythritol triacrylate, stannous octoate, hydroquinone monomethyl ether (about the overall amount) make-up. The covering movie of this paint is exceptional in versatility, abrasion resistance, chemical resistance, and so on. Traditional coating approach construction. In the industrial area, along with being suitable for layer timber, it is additionally widely made use of in printing ink, paper varnish, solder safety layer, and so on.

Its resources ratio is as complies with by weight: 100 parts of alkyd resin; 35-45 parts of castor oil; 15-25 parts of diatomaceous planet; 30-40 parts of xylene; -45 parts; 1-10 parts of hydroquinone monomethyl ether; 5-15 parts of organic bentonite; 15-35 parts of stannous octoate; 20-30 parts of pigments as well as fillers; 5-25 parts of tetraethylene diacrylate; 15-35 parts of cobalt acid; 10-30 parts of trimethylolpropane triacrylate; 30-40 parts of toughening agent; 10-30 parts of hexanediol diacrylate; 10-20 parts of manganese naphthenate; 15-25 parts of triazole; uniform color of the finishing movie, viscosity 80-120s; excellence 25-35μm, covering power 90-100g/ cm2; surface dry 0.1-0.3 h, difficult dry 0.5-1.5 h; water resistance 5-15d, Can be widely created and continuously replace existing materials.
