  • Best Practices for Dow Dowsil P5200 Adhesion Promoter

    *See Terms of Use Below

    1. Surface Preparation

      The active ingredients must thoroughly wet-out and coat the bonding surfaces. Mild abrasion, solvent cleaning, plasma, corona discharge and other pre-treatments have been used to clean and enhance surface reactivity to bonding. In general, light surface abrasion is recommended whenever possible, because it promotes good cleaning and increases the surface area for bonding. Surfaces should be cleaned and/or degreased with Dow Corning ® brand OS Fluids, naphtha, mineral spirits, methyl ethyl ketone (MEK) or other suitable solvents that will remove oils and other contaminants that may be present. A final surface wipe with acetone or IPA may also be helpful. Different cleaning techniques may give better results than others. Users should determine the best technique for their applications.

    2. Application

      If this product is used as a cleaner and primer, the two-cloth wipe method of cleaning must be used. Using a cloth, apply a thin film of DOWSIL P5200 Adhesion Promoter to a clean, non-porous surface and immediately wipe the primed area down with a second clean, dry cloth.

      If this product is used only as a primer, apply DOWSIL P5200 Adhesion Promoter to clean surfaces in a thin film using a cloth or brush.

      The sealant may be applied after the primer has dried (approximately 30 minutes in cold conditions and 10 minutes in warm conditions).

      All surfaces cleaned and primed with DOWSIL P5200 Adhesion Promoter should be sealed on the same day the primer is applied, sealant should not be applied longer than 8 hours after primer application. If the sealant cannot be applied within this time, surfaces must be recleaned and reprimed before applying the sealant.

    3. Curing

      These products require moisture in the air to cure, and are generally cured at room temperature and in a range of 20 to 90 percent relative humidity for 1 to 2 hours. Low humidity and/or low temperature conditions require longer cure times. Mild heat acceleration of the cure rate may be possible but temperatures above 60°C (140°F) are not recommended. During application, the carrier solvent typically evaporates off quickly (except in the case of Dow Corning 1593 Cleaner/Primer, where the solvent does not evaporate at all), allowing the active ingredients to begin to react with atmospheric moisture and bonding surfaces. For optimal bonding, different cure times may be required for different temperature and humidity conditions. Users should determine the best cure schedule and conditions for their applications. The desired silicone elastomer should be applied after the primer, prime coat or adhesion promoter has fully cured.
