Abstract: Polyorganosiloxane compositions for surface treatment comprising:(A) a polydiorganosiloxane having a viscosity of 50 cSt to 10,000,000 cSt at 25.degree. C., the terminal units of which are blocked by hydroxy groups;(B) a curing agent which comprises a mixture or a partially reacted mixture of:(1) a polyorganosiloxane composed of structural units represented by the formula:(R.sup.1).sub.a SiO(.sub.4-a)/2wherein, R.sup.1 s are the same or different and each represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbyl group and at least two R.sup.1 s out of the total R.sup.1 s in a molecule are monovalent hydrocarbyl groups substituted by an epoxy-containing group; and a represents an integer of 1 to 3, and having a polymerization degree of 10 to 5,000;(2) a silane and/or a siloxane having a substituted or unsubstituted amino group bonded to a silicon atom via at least one carbon atom and also having at least one alkoxy group bonded to a silicon atom;at a proportion of 0.

Abstract: Adhesive silicone composition with good adherence to various substrates comprising a silicone mixture selected from the class consisting of a mixture of a polysiloxane having glycydoxy or epoxycyclohexyl groups in combination with an amine functional silane or siloxane. These compositions provide good water resistant shelf-adhering coatings to plastics, paper and rubber.

Abstract: A self-bonding polysiloxane coating composition having therein a hydroxyl end-blocked polydiorganosiloxane polymer, and a polysiloxane having epoxy functional groups mixed with an amino-functional silicone compound. To increase the cure rate of the composition there may be also in the composition a hydride-containing polysiloxane and a metal salt of a carboxylic acid.
