Several different curing agents are available for two-component RTV silicone rubber compounds to provide a choice of cure speed, mixing ratio, or deep section cure. DBT (dibutyl tin dilaurate) and STO (stannous tin octoate) are clear, easily pourable liquids. RTV9950 is a white paste, RTV9910 is a beige paste, and RTV9811 is a beige pourable paste. All are based on metal soaps. These curing agents are appropriate to use with the following Momentive Performance Materials products: RTV11, RTV21, RTV31, RTV41, RTV60, RTV88, RTV511, RTV560, and RTV577.
Paste version of DBT. G Convenient 10:1 mixing ratio for use in automatic dispensing or hand operations. G Excellent color contrast with red RTV base compounds provides visual evidence of complete mixing. G Provides extended pot life over RTV9950.
These sunglasses were a gift to our grandson. He is a fairly new pilot and wanted these sunglasses as a birthday gift. He is very happy with them.
The staff at Pilots HQ were great to deal with and managed pto get the sunglasses to me just in time for our grandson’s birthday.
Thanks for the help.
Heard about Boelube for years. Finally had a chance to try it on several projects. It definitely works well and better than anything else I have ever tried. Would recommend.
