We are producer of electronic blocks. We are use for capsulation our blocks silicone RTV627, but earlier we was using silicone CRTV-6405. We want find provider silicones CRTV-6405. In month we are use up 400-500 kilogram of silicones. Our firm locat

Material, fumes, cured or uncured, all are suspect. Silicone gets on an operator's hands, that operator handles components ( even a day or more later ) silicone is transferred to the solder connections = contamination. Process and workcell control

Comments are: * General purpose RTV (RTV-108) releases an acetic acid (vinegar) during cure and corrodes copper, brass and sensitive metals. It is therefore NOT for use in delicate electrical or electronic applications. However, there is an electrica

Common RTV does out-gas causing corrosion. NASA allows use of non/low-out-gassing RTV. Try the following companies: * Ablestik Electronic: Materials, 20021 Susana Road, Rancho Dominguez, California 90221 U.S.A., 310-764.4600, F 310-764-2545 * Arlon

Is it acceptable to apply an acrylic conformal coat, cure and then apply a silicone RTV on top (for staking tall components)? Should there be a concern with the bond between the acrylic and the RTV?

We are experiencing corrosion and subsequent pcb contamination from the RTV material used to secure a Power Supply. The degradation takes place over a few weeks. The power supply vendor is balking at liability, our OEM customer is screaming. Anyone

We bet your customer has freaked-out. Some common RTV out-gas ammonia during cure. Many types of RTV depend on strong acetic acid to work. Also, ammonia plus water in the air produces ammonium hydroxide, an aggressive alkali. We've talked about this

We maintain shelf life on all of our RTV silicon compounds.

We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your

3145 is methoxy cure, so the cure by product is methanol.
