Shelf Life Details Shelf life is indicated by the “Use Before” date found on the product label., For best results, Dow RTV adhesives should be stored at or below the storage temperature listed on the product label. Special precautions must be taken to prevent moisture from contacting these materials. Containers should be kept tightly closed with head or air space minimized. Shelf Life Type from date of manufacture Shelf Life (mon) 15 Not Good For
Don't Use With Non-reactive metal substrates, Nonreactive plastic surfaces, Plastic substrates that are highly plasticized, Teflon, Polyethylene, Polypropylene, Rubber substrates that are highly plasticized -
Best Practices for Dow Dowsil SE 9186
-
Surface Preparation
All surfaces should be thoroughly cleaned and/or degreased with DOWSIL™ brand OS Fluids, naphtha, mineral spirits, methyl ethyl ketone (MEK) or other suitable solvent. Solvents such as acetone or isopropyl alcohol (IPA) do not tend to remove oils well, and any oils remaining on the surface may interfere with adhesion. Light surface abrasion is recommended whenever possible, because it promotes good cleaning and increases the surface area for bonding. A final surface wipe with acetone or IPA is also useful. Some cleaning techniques may provide better results than others
users should determine the best techniques for their particular applications.
-
Testing
Due to the wide variety of substrate types and differences in substrate surface conditions, general statements on adhesion and bond strength are impossible. To ensure maximum bond strength on a particular substrate, cohesive failure of the product in a lap shear or similar test is needed to ensure compatibility of the adhesive with the substrate being considered. Also, this test can be used to determine minimum cure time or to detect the presence of surface contaminants such as mold release agents, oils, greases and oxide films.
