Crosslinkable compositions

A process for the preparation of coatings which repel tacky substances, comprising;

• applying a crosslinkable composition containing
• (1) an organosilicon compound having radicals containing aliphatic carbon-carbon multiple bonds, and
• (2) an organosilicon compound having Si-bonded hydrogen atoms, or
• (3) an organosilicon compound having both radicals with aliphatic carbon-carbon multiple bonds and Si-bonded hydrogen atoms,
• (4) a catalyst which promotes the addition of Si-bonded hydrogen onto an aliphatic multiple bond, and
• (5) an agent which inhibits the addition of Si-bonded hydrogen onto an aliphatic multiple bond at room temperature, of the formula ##STR7## in which R.sup.1, R.sup.2, R.sup.4, R.sup.5 and R.sup.6 are identical or different and are a hydrogen atom or a monovalent, substituted or unsubstituted hydrocarbon radical having 1 to 12 carbon atoms per radical,
• R.sup.3 is a divalent hydrocarbon radical having 1 to 6 carbon atoms per radical,
• X is a radical of the formula --OH, --Cl, Br or --CN, and
• x and y are identical or different and are 0 or 1, with the proviso that there is at least one double bond, to a surface to be made repellant and then curing the composition.
