FRP grating raw resin

Unsaturated polyester resin. Viscous solution mainly unsaturated linear polyester resin, an unsaturated dibasic acid and dihydric alcohol generated with the monomer having a polymerizable capacity formed. Under the action of an initiator or thermal energy to form the body of the polyester resin to correlate reaction. Common unsaturated dibasic acids are maleic anhydride ,, diol is ethylene glycol, monomer is a vinyl compound such as styrene. The main system for fiberglass and coatings, also used in making cement and compression molding powder. Form at the bottom First, the characteristics and main purposes:?? M-191DC is dicyclopentadiene unsaturated polyester resin Universal, moderate the viscosity of the resin, reactive medium, fast curing characteristics. After solidification shrinkage products, mechanical strength in general, for a variety of common hand burnt fiberglass products. ? Second, the liquid resin technical indicators:?

Fourth, note:??? Transport should be consistent with the provisions of GB 190. Product Storage Keep in a highly recommended below 25 ℃, avoid direct sunlight, exceeding the storage conditions may affect resin properties, such as viscosity and gel time. In particular thixotropic resin should be mixed thoroughly before use. Holding barrel sealed to prevent the ingress of moisture, tighten the lid. Resin ingredients such as improper use can cause injury, must avoid contact with skin, eyes, must wear the necessary protective equipment and clothing during use.
