Business Information

Shelf Life Details	For best results, Dow Corning 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. Partially filled containers should be purged with dry air or other gases, such as nitrogen. Shelf life is indicated by the “Use Before” date found on the product label.
Shelf Life Temperature (°F)	90
Shelf Life Type	from date of manufacture

Not Good For

Don't Use With	Non-reactive metal, Non-reactive plastic, Teflon, Polyethylene, Polypropylene, Plastic substrates, Rubber substrates, Highly plasticized

Best Practices for Dow Dowsil SE 9187 L Adhesive

*See Terms of Use Below
1. Surface Preparation
  
  All surfaces should be thoroughly cleaned and/or degreased with Dow 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.
2. 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, 100 percent cohesive failure of the adhesive in a lap shear or similar adhesive strength test is desired. This ensures compatibility of the adhesive with the substrate being considered. Also, this test can be used to determine minimum cure time or can detect the presence of surface contaminants such as mold release agents, oils, greases and oxide films.
