Shelf Life Details Shelf life is indicated by the “Use Before” date found on the product label., For best results, Dow Corning one-part products require cold storage at or below -5°C (23°F). Special precautions must be taken to prevent moisture from contacting these materials. Containers should be kept tightly closed with head space minimized. Partially filled containers should be purged with dry air or other gases, such as nitrogen., Check the product label for specific storage conditions. Shelf Life Type From date of manufacture Shelf Life (mon) 6
Best Practices for Dow JCR 6109
Surfaces should be clean and dry. Recommended cleaning methods include Dow Corning® brand OS Fluids, naphtha, mineral spirits, methyl ethyl ketone (MEK) or other suitable solvent. Rougher surfaces tend to promote adhesion of silicones to other surfaces.
These products are also compatible with commercially available equipment and industry standard processes. These materials can be dispensed or molded depending on the product and application.
Dow Corning OS Fluids are recommended to clean cured or uncured silicone residue from application equipment.
If a substrate or material is questionable with respect to potentially causing inhibition of cure, it is recommended that a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured silicone indicates incompatibility and inhibition of cure.
