The invention provides a process for the production of a pressure sensitive adhesive, comprising dissolving a particulate solid MQ silicone resin having a bulk density in the range 0.4-0.9 g/cmin a volatile solvent, and dissolving a polydiorganosiloxane having a viscosity of 0.1 to 40,000 Pa&#xb7;s at 25&#xb0; C. in the volatile solvent before, simultaneously with or after dissolving the solid MQ silicone resin. The process of the present invention allows the production of a pressure sensitive adhesive in a solvent different from the solvent in which the MQ silicone resin was prepared.

Silicone pressure sensitive adhesives

A method for treating substrates to render them hydrophobic includes penetrating the substrate with a halosilane vapor.

Method for treating substrates with halosilanes

The present invention relates generally to a novel process for making a solid solventless MQ resin comprising the steps of (1)(A) feeding at least one MQ resin dispersed in a volatile solvent into an extrusion device, (2) removing the volatile solvent to form a solid solventless MQ resin; and (3) recovering the solid solventless MQ resin, provided steps (1) to (3) are completed without the addition of a linear silicone fluid.

Process for the preparation of solid solventless MQ resins

A process for stabilising the viscosity of an amino-functional siloxane polymer comprises adding a dialkoxydialkylsilane to the amino-functional siloxane polymer or to the reagents from which the amino-functional siloxane polymer is produced.

Methods for making silicone-organic copolymers are disclosed involving the manipulation of polymerization chain terminators allowing for polymer molecular weight control.

Methods for making silicone-organic copolymers

A method for preparing dispersions of solid salts of fatty acids in low polarity liquids where a concentrated mixture of at least 50 percent of the solid salts of fatty acids in a low polarity liquid is subjected to high shearing forces, until the average particle size of the solid salts of fatty acids is less than 3 micron. The dispersion may then be diluted with the low polarity liquid to a lower concentration. The solid salt of the fatty acid is most preferably magnesium stearate, and the low polarity liquid is preferably a polydimethylsiloxane fluid having a viscosity of less than 100 centistoke (mm /s).

A method of obtaining fine-grained, free-flowing powdered silicone resins is disclosed. The powdered silicone resins contain very low or no residual aromatic solvents or other volatile organic compounds. The method includes the steps of (1) preparing a solution of an MQ silicone resin dissolved in a volatile liquid organosilicon solvent, such as hexamethyldisiloxane, and (2) spray-drying the solution obtained in step (1) to produce the silicone resin powder.

Method of preparing powdered silicone resins

Solventless silicone resins, which exhibit a high degree of reconstitution, are produced in forms such as powders and flakes. The degree of reconstitution is judged by the fact that silicone resin/fluid alloys produced therefrom exhibit only a minor shift in T.sub.g, the glass transition temperature, in comparison to analogous alloys produced from solvent dispersed (virgin) resin. Resin, and preferably virgin resin, is dispersed in a volatile liquid dispersant and blended with a nonvolatile silicone fluid. Thereafter, the volatile liquid dispersant is removed by means such as spray-drying or evaporation, resulting in the solventless resin forms of the invention.

Method of preparing solventless silicone resins that exhibit superior

Solventless, thermoplastic silicone pellets are prepared blending silicone resins (A) of the MQ-type and with predominantly linear silicone fluids (B), such as polydimethylsiloxane liquids and gums, to substantially homogeneity. The blends are heated to a predetermined compression-forming temperature, compression-formed to a densified mass and shaped into a pellet form. The composition of the pellets is balanced such that the pellets exhibit plastic flow at the predetermined compression-forming temperature and resist agglomeration at temperatures at or below a predetermined maximum storage temperature.
