Ortho-diallyl Bisphenol A Molecular formula: C21H24O2 Molecular weight: 308.42 CAS NO: 1745-89-7 Specification: Appearance Colorless or yellowish liquid Purity % min 96 Viscosity ( cps ) 600-1200 Application: It is principally used in the modifier of Bismaleimide( BMI) . It can reduce the applying cost of BMI resin greatly, improve its operation and techics, and improve its tenacity, heat-resistance and model forming. BMI can be used in 1) .electrical insulation materials, insulated lacquer, high temperature resistant varnish of circuit board with copper coated, layered board, model plastic etc. 2) .friction-resistant material, diamond grinding wheel, heavy-burdened grinding wheel, brake slice, high temperature resistant adhesive of axletree etc. 3) .transverse spaceflight configurable material. 4) .functional material. As an age-resistance of rubber, it can improve its age-resistance greatly with 1-3% BBA added.
