Best Practices for Dow JCR 6115
-
Surface Preparation
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.
-
Application
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.
-
Clean-Up
Dow Corning OS Fluids are recommended to clean cured or uncured silicone residue from application equipment.
-
Testing
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.
