Chemtronics Coventry Multi-Phase Carrier Solvent
Coventry 12809 Multi-Phase Carrier Solvent is a non-ozone depleting carrier solvent and swelling agent. It is a saturated mixture of n-octane and perfluorocarbon (PFC). The n-octane provides solvency, while the PFC provides an inert perfluorocarbon vapor blanket above the liquid mixture. These vapors impede the flammability of the n-octane. As the perfluorocarbon evaporates during use, supplemental PFC moves into the saturated solution. Although 12809 shows no closed cup flash point up to its boiling point, the primary component, n-octane is flammable. Therefore, Coventry 12809 should be handled and shipped as a flammable solvent. Coventry 12809 is used to replace CFCs, HCFCs, and flammable solvents as a carrier solvent for lubricants and coatings. It is especially effective as a silicone solvent and as a swelling agent for silicone fabricated parts.
For coating or deposition operations, the solution should be gently agitated during coating to insure homogeneity in the solution in order to provide a uniform coating. The parts to be coated are then dipped into the PFC + n-octane + coating solution, removed, and then dried or cured. For silicone swelling applications, submerge the portion of the tube or part to be swelled into the PFC+n-octane solution phase solvent until the desired swelling is obtained. Remove and assemble. The tube or fitting will return to its original dimensions as the n-octane evaporates and the connection will be complete.
