Some individuals have seen the need to control the relative humidity at 40 to 60 percent at ambient temperatures. The fix is to remove the film to expose bare aluminum before application of the primer. Adcole has had some success in incorporating granular material such as glass beads or silicone carbide grit into the RTV by precoating the beads with dilute primer and drying before mixing into the base material. When cured, the final product will have lower thermal expansion, greater stiffness and less compressibility, as one might expect. Working time 1 Hr.
Material has a limited life and it is stored cold.
Keep the relative humidity near 40 to 60 percent for best results. Roger S. Reiss is based in Worcester, Massachusetts. This is the second in a series of technical group profiles OE Reports will be running in the coming months. We want to introduce you to these groups, and provide a brief overview of their areas of interest and the kinds of activities they are involved in. We'd like people to start thinking about smart structures as a whole, and not just the pieces.
