A preparation for the abhesive coating of baking tins, baking molds, frying pans, metal pots and the like is disclosed. The preparation which comprises predominantly a heat-curable, polyol-modified polysiloxane A and 0.05 to 4% by weight, based on polysiloxane A, of a linear siloxane B that is capable of reacting with polysiloxane A. The modified polysiloxane A is obtained by reaction of a polysiloxane A1 of the general formula. ##STR1## wherein OR.sup.1 is an alkoxy group, derived from a primary or scondary alcohol with 1 to 4 carbon atoms,

Abhesive coating preparation and method of abhesively coating utensils

Heat-curable vehicles and a process for their preparation which can be diluted with water after neutralization, by the partial reaction of a low molecular weight alkoxysiloxane with a low molecular weight polyol having carboxyl groups and at least two hydroxyl groups. The vehicle dissolves in water, optionally in the presence of slight amounts of auxiliary solvents, highly concentrated solutions being obtained with a solids content of 80 weight percent or higher, yet a relatively low viscosity.

Process for the synthesis of a water-dilutable, heat-curable

The invention relates to a process for heat-curable silicone resins and their synthesis by reacting a low molecular weight alkoxysilane with a low molecular weight polyol with 2 to 6 hydroxyl groups in the molecule. The reaction products have a very low viscosity, which is suitable for processing when about 20% of solvent, based on the non-volatile resin, are added.

Process for the synthesis of heat-curable silicone resins

The invention relates to a process for the preparation of heat-curable resins, usable especially as electrically insulating resins, by the reaction of alkoxy siloxanes of the formula ##STR1## in which OR.sup.1 represents an alkoxy group of primary or secondary aliphatic alcohols with 1 to 4 carbon atoms,

Process for the preparation of heat-curable silicone resins usable

A composition for the abhesive coating of metallic cooking surfaces composed of a heat-curable polysiloxane resin, based on the silicone resin, and 0.05 to 4 weight percent of a compound having the formula ##STR1## in which R.sup.1 and R.sup.2 are the same or different and represent a methyl or phenyl residue, with the proviso that at least 80 mole percent of these residues are methyl residues,
