Processing and Safety Guidelines
GP-657 shows a very rapid conversion to crosslinked silicone rubber when exposed to atmospheric moisture. When mixing with solvents, fillers and other materials, make sure that dry conditions are maintained. Containers of GP-657 must be tightly sealed in storage and pressurized slightly with dry nitrogen when transferring or before resealing.
GP-657 is supplied in 5-gallon (40 lbs.) pails, 55-gallon (440 lbs.) drums and 330-gallon (2640 lbs.) totes. GP-657 is Moisture Sensitive, keep containers tightly sealed when not in use.
