Abstract
The invention provides for, inter alia, the use of solvent-, water- and emulsifier-free preparations for the friction-reducing coating of rubber profiles, comprising (a) about 0.5 to about 35, preferably about 2 to about 5, parts by weight of a curable siloxane and (b) about 65 to about 99.5, preferably about 95 to about 98, parts by weight of low molecular weight volatile silicone oils and, if appropriate, (c) customary auxiliaries and additives.
Claims16
A friction-reducing coating for a rubber profile that does not conain a solvent, water or an emulsifier which comprises:
- (a) about 0.5 to about 35, parts by weight, based upon the total amount of components (a) and (b), of a curable siloxane and
- (b) about 65 to about 99.5, parts by weight based upon the total amount of components (a) and (b), of at least one low molecular weight volatile silicone oil of formula (I) and/or a cyclic compound of formula (Ia)
- 3
- where
- (c) optionally auxiliaries or additives.
The friction-free coating composition which comprises a mixture of linear and cyclic silicone oils.
