Application of hydrosulphonyl silicone oil

Using thiol in light or electron beam and photosensitizer, can rapidly and unsaturated bond addition, mercapto alkyl silicone oil has been widely used in preparation semiconductor coating, polymorphism vulcanized silicone, optical fiber coating, paper isolation agent and plastic surface coating products. In addition, by utilizing the adsorption of the hydrosulphonyl of materials has also been in the release agent, fixing agent and fabric finishing agent obtained successful application.
(1) Japan Shin Etsu semiconductor coating production of semiconductor special one component solvent-free UV curable alkenyl / thiol siloxane coatings (KJR8050S), in visible light and solar light irradiation was not cured, and in 80W/cm high-pressure mercury lamp (the distance of 10cm) irradiation under, don't need catalyst and high temperature, and within 10 seconds can be cured into elastic modulus, resistance to - 50 ~ 200 DEG C hot and cold impact, good heat resistance and good adhesion to silicon, ceramics, copper and other materials, can avoid damage to semiconductor structure and lead in the plastic, can also be protective element in storage and use is not in the course of water vapor erosion.
(2) polymorphism vulcanized silicone general condensation type RTV silicone, depth of the curing time long, is difficult to achieve continuous, fast curing operation, if mixed with sulfhydryl and vinyl and UV curing system, can accelerate the curing rate, but also overcome the problem of poor light curing adhesive.
(3) optical fiber coating by mercapto alkyl silicone oil and vinyl silicone oil preparation of UV curable coatings for optical fibers, with curing speed is very fast (<1S) and no H2 evolution and other advantages. Developed by the U. S. Dow Corning Optigard, the paint in the medium pressure mercury lamp 80W/cm apart 10cm under, irradiation 0.3s can be cured into low glass transition temperature, in 60 ~ 125 DEG C temperature range of the modulus of elasticity changes small, suitable for use in harsh conditions of optical fibers.
(4) paper and plastic film isolating agent using low temperature fast curing thiol / vinyl photo curable siloxane as paper isolation agent can be exempted from solution, emulsion and platinum catalyst and forming isolation agent need heating shortcomings, on the production of polyethylene, polypropylene, polystyrene, polyester film as a base material of pressure-sensitive adhesive products especially welcome.
In addition, the release of excellent mercapto silicone oil, successfully used in electrostatic copier toner melting part, prevent toner adhesion. The property of the product's resistance to temperature and durability can be improved by the cooperation of the thiol and the curing agent. Join in the anti caking treatment coating, wool, with durable shrinkproof etc.. The thermal oxidation stability of the latter can be improved by mixing with two methyl silicone oil.
