Title:
ONE-PART ROOM-TEMPERATURE CURABLE COMPOSITIONS ON BASIS OF ORGANOSILICON COMPOUNDS AND TITANIUM CURING CATALYSTS
Document Type and Number:
WIPO Patent Application WO/2018/076337
Kind Code:
A1
Abstract:
Provided are one-part room-temperature curable compositions (RTV-1 compositions) on the basis of organosilicon compounds which is less toxic compared to conventional compositions that contain organotin compounds and, at the same time, has excellent curing properties, a skin formation time which allows proper handling and tooling, and excellent storage stability. In particular, the present invention is directed to compositions comprising: (A) at least one organosilicon compound containing condensable groups; (B) at least one curing agent comprising a compound having the formula R'Si (OOCR")3, wherein R' is C3-C6 alkyl, and R" is the same or different and independently selected from C1-C6 alkyl; (C) at least one curing catalyst comprising an organotitanium compound; and (D) at least one filler. By using a combination of organotitanium compounds (C) with curing agents (B) the compositions show excellent curing properties, suitable skin formation time and excellent storage stability.
