Pure polyoxyethylene resin

Polyoxyethylene resin is the abbreviation of unsaturated polyester adhesive. Unsaturated polyester adhesive is mainly composed of unsaturated polyester resin, initiator, accelerator, filler, thixotropic agent, etc. A linear structure (see linear polymer) polyester resin containing - CH = ch - double bond in the main chain. It can be mixed with olefin monomers such as styrene, acrylate, vinyl acetate, etc., polymerized to insoluble immiscible products at room temperature under the action of initiators accelerators. The abbreviation of unsaturated polyester is up. It is mainly used to produce coil coating. Polyester resin is a general term for polymer compounds formed by polycondensation of diols diols polyols polybasic acids.

Polyester resin is divided into saturated polyester resin unsaturated polyester resin. Unsaturated polyester adhesive is mainly composed of unsaturated polyester resin, pigments fillers, initiators other additives. The adhesive has the advantages of low viscosity, easy wetting, good processability, high hardness, good transparency, high brightness, fast curing under room temperature pressure, good heat resistance excellent electrical properties. Its disadvantages are high shrinkage, low adhesive toughness, poor chemical medium resistance water resistance, so it is used in non structural adhesives. It is mainly used for gluing glass fiber reinforced plastics, hard plastics, concrete, electric can sealing, etc.
