octadecyl methacrylate is a colorless or yellowish liquid; Its relative density is 0. 860; Boiling point (6. 7kPa) 270 deg C; Flash Point (open) 192 deg C; Glass transition temperature of Tg-100 deg C; Solubility parameter 16J/cm3.
It is obtained by subjecting stearyl alcohol (octaalkanol) obtained by hydrogenation of stearic acid to an esterification reaction with methacrylic acid.
mainly used in coatings, adhesives, lubricating oil additives, fiber treatment agents and textile, leather and paper processing emulsifier.
resin production raw materials, the skin and mucous membranes of the human body have different degrees of stimulation, can cause skin allergic reactions and inflammation; At the same time also pay attention to the harm of resin dust on the human body, long-term inhalation of high concentrations of resin dust, can cause lung lesions. Most of the resin has a common hazard characteristics: open flame, high temperature flammable, and oxidant exposure will cause combustion risk, therefore, the operator to improve the operating environment, the operating area and the non-operating area shall be intentionally drawn apart, automated and closed as far as possible, and ventilation facilities shall be installed.
