Study on ageing characteristics and evaluation methods of RTV silicone rubber in high humidity area.

open access: yesPLoS ONE, 2021
Due to high humidity, the ageing of room temperature vulcanized silicone rubber (RTV) has been a serious problem in Southwestern China. In order to solve the problem of RTV life prediction, the aging classification method was established by analyzing the

Measured limits to contamination of optical surfaces by elastomers in vacuum [PDF]

open access: yes, 1995
We have monitored the reflectivity of mirrors that were exposed to a fluoroelastomer (3M-Fluorel 2176) and a room-temperature vulcanizing silicone rubber (RTV-615) in vacuum. The 95% confidence limit on the decrease of mirror reflectivities was less than
