Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
40 words
A one-component RTV material comprising a mixture of: a) polyorganosiloxanes having reactive terminal groups, b) polyorganosiloxanes having nonreactive terminal groups, c) silane crosslinkers, d) reaction products of titanates with β-dicarbonyl compounds and citrates, e) fillers, and optionally f) other additives.
Claim 2
Dependent Claim
40 words
A one-component RTV material comprising a mixture of: a) polyorganosiloxanes having reactive terminal groups, b) polyorganosiloxanes having nonreactive terminal groups, c) silane crosslinkers, d) reaction products of titanates with β-dicarbonyl compounds and citrates, e) fillers, and optionally f) other additives.
Claim 3
Dependent Claim
71 words
A one-component RTV material according to claim 1, wherein the titanates are of the formula ##STR9## wherein represents identical or different linear or branched C 1 to C 20 -alkyl groups or alkoxyalkyl groups, which optionally have one or more OH groups on one or more carbon atoms at any position; R 1 corresponds to an R group or hydrogen or is a C(O)OR group; and n is 0 or 1.
Claim 4
Dependent Claim
42 words
The one-component RTV material of claim 1, wherein said reaction product of said titanite with said β-dicarbonyl compound and said citrate is present in an amount of from about 0.1 to 10% by weight of said polyorganosiloxane having a reactive terminal group.
