Novel enoxy functional silanes of the general formula: ##STR1## are provided wherein R.sup.1 is a monovalent hydrocarbon radical having 1 to 8 carbon atoms; R.sup.2, R.sup.3 and R.sup.5 are monovalent hydrocarbon radicals having 1 to 13 carbon atoms; R.sup.4 is hydrogen or a monovalent hydrocarbon radical of 1 to 13 carbon atoms; a is an integer equal to 0 to 3; b is an integer equal to 1 to 4, and the sum of a+b equals 1 to 4.

Silicone compounds

A novel, shelf-stable, one-component alkoxy-functional RTV composition having therein as a scavenger an alkoxy-functional silazane compound. The silazane compound can be cyclic or linear and can also be an integrated cross-linking agent.

Novel scavengers for one-component RTV compositions

Compounds of the formulae: ##STR1## wherein, Z and Y are each alkylene or oxy-alkylene containing one to about five carbon atoms in the principal chain or said alkylene substituted with OH, alkanoyloxy, alkoxy, mercapto or alkylmercapto;

Substantially silanol-free, alkoxy functional RTV silicone rubber composition. The silanol and alkoxy groups in the composition are scavenged by the use of scavenging leaving groups which are present either in the cross-linking agent or in a separate compound. The scavenging leaving group in the instant composition is a heterocyclic amide functional group.

RTV silicon compositions and processes

Stable, substantially acid free, one package organopolysiloxane compositions are provided which have a base polymer, a condensation catalyst, a silane scavenger for hydroxy functional groups having cycloaliphatic enoxy functionality, and a curing accelerator, said compositions being curable upon exposure to atmospheric moisture to translucent and colorless tack-free elastomers.

Crosslinkers for RTV compositions

There is provided a one package RTV composition which is convertible to a tack-free elastomer comprising:

Scavengers for RTV silicone rubber compositions

There is provided a one package silicone RTV composition which is convertible to a tack-free elastomer, comprising:
