Dow 737 RTV neutral cure clear sealant is a non-slumping, one-component, fast cure paste that offers the user exceptional adhesion to many plastic, glass, metal, rubber, and painted surfaces. With that connection, the adhesive doesn’t react with or corrode most plastics or metals; with a few exceptions in some not so standard applications. The applications to avoid are situations with continuous water immersion, materials that bleed oils, plasticizes, solvents, impregnated wood, or oil-based caulks. As well, being in a confined space where the sealant is not exposed to atmospheric moisture will lead to a non-complete cure.
This clear neutral cure sealant is a very diverse product with a wide range of applications but was specifically designed for OEM and assembly uses. The more general use of the product includes the sealing and bonding of formed-in-place gasketing and maintenance applications. The specific uses of Dowsil 737 RTV sealant comprises: waterproofing electrical components, protecting instrumentation assemblies, sealing coaxial connectors, and connecting plastic moldings to plastic substrates for trim applications, such as decals. This product is also commonly used for the sealing of freezer and refrigerator liners.
