摘要:
A heat-curable fluoropolyether adhesive composition comprising (A) a linear polyfluoro compound having at least two alkenyl groups and a perfluoropolyether structure, (B) a fluorinated organohydrogensiloxane having at least two SiH groups, (C) a platinum group metal catalyst, (D) an organosiloxane having at least one SiH group and at least one epoxy and/or trialkoxysilyl group, and (E) a compound having at least two allyloxycarbonyl groups can be cured to metal and plastic substrates by heating at a temperature from 20° C. to less than 100° C.
摘要:
An addition curable silicone adhesive composition that can be cured at room temperature, exhibits favorable adhesiveness, and yields a cured product upon curing that exhibits excellent transparency and a suitable degree of hardness. The addition curable silicone adhesive composition of the present invention comprises: (A) a diorganopolysiloxane containing at least two silicon atom-bonded alkenyl groups, (B) a three dimensional organopolysiloxane resin that comprises trifunctional siloxane units and/or tetrafunctional siloxane units represented by SiO4/2, (C) an organohydrogenpolysiloxane containing at least two silicon atom-bonded hydrogen atoms, (D) a hydrosilylation reaction catalyst, (E) an organosilicon compound as an adhesion-imparting agent, and (F) an acid anhydride that is liquid at room temperature.
摘要:
An addition reaction curing type silicone rubber composition comprising (A) an alkenyl-containing diorganopolysiloxane, (B) an alkaline earth metal carbonate powder surface treated with a diorganopolysiloxane, (C) an organohydrogenpolysiloxane, and (D) a platinum group metal catalyst has improved storage stability in that it gives off little or no hydrogen gas during storage. The composition has improved adhesion and a good ability to protect electric or electronic parts from corrosion and finds typical use in the sealing of electric or electronic parts.
摘要:
In an addition type silicone adhesive composition comprising (A) an organopolysiloxane having at least two silicon-bonded alkenyl groups, (B) an organohydrogen-polysiloxane having at least two SiH groups, and (C) a hydrosilylation catalyst, the incorporation of (D) a (meth)acryloxyalkyl-modified linear or cyclic organopolysiloxane having a viscosity of 5-10,000 mPa-s at 25° C., and (E) a zirconium compound allows bond strength to develop even by brief heating and minimizes discoloration after a long-term heat test.
摘要:
When an air bag is prepared by laying a pair of silicone rubber-impregnated and/or coated base fabric pieces one on the other, with the coated surfaces of the pieces inside, and joining peripheral portions of the pieces together to form a bag, an addition reaction curing type silicone rubber composition which cures into a silicone rubber having an elongation at break of at least 1000% is used as a sealer and applied to the peripheral portions of the base fabric pieces, thereby achieving improved adhesion therebetween.
摘要:
When silicone rubber-impregnated and/or coated fabric pieces are mated, with their treated surfaces inside, and joined along a periphery to form a bag, a silicone rubber composition having a tris(trialkoxysilylalkyl) isocyanurate blended as an adhesion promoter is used as a sealer where the peripheral portions of the fabric pieces are joined together whereby an improved bond is established therebetween.
