    Business Information
    Shelf Life Details Shelf life is indicated by the “Use By” date found on the product label. For best results, Dow Corning silicone encapsulants should be stored at or below 25°C (77°F). Special precautions must be taken to prevent moisture from contacting these materials. Containers should be kept tightly closed and head or air space minimized. Partially filled containers should be purged with dry air or other gases, such as nitrogen.

  • Best Practices for Dow 96-082 A & B Encapsulant

    *See Terms of Use Below

    1. Surface Preparation

      In applications requiring adhesion, priming will be required for the silicone encapsulants. See the Primer Selection Guide or the correct primer to use with a given product. For best results, the primer should be applied in a very thin, uniform coating and then wiped off after application. After application, it should be thoroughly air dried prior to application of the silicone elastomer. Additional instructions for primer usage can be found in the Dow Corning literature, “How To Use Dow Corning Primers and Adhesion Promoters” (Form No. 10-366) and in the information sheets specific to the individual primers.

    2. Mixing

      Dow Corning silicone 1:1 encapsulants are supplied in two parts that do not require lot matching. The 1:1 mix ratio, by weight or volume, simplifies the proportioning process. To ensure uniform distribution of filler, Parts A and B must each be thoroughly mixed prior to their combination in a 1:1 ratio. When thoroughly blended, the Part A and B liquid mixture should have a uniform appearance. The presence of light-colored streaks or marbling indicates inadequate mixing and will result in incomplete cure. Due to the fast-curing characteristics of some encapsulants included in this data sheet, automated mix and dispense equipment should be utilized.

    3. Deairing/Degassing

      In applications sensitive to air entrapment, deairing with 28 to 30 inches Hg vacuum is required.

    4. 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 gel indicates incompatibility and inhibition of cure.

Cure Temperature Test Methods
Cure Temperature Cure Time Test Method
150°C These data were collected on 50-100 gram samples of a lot believed to be typical and should be used as initial estimates of cure times. Times will vary slightly from batch to batch and can be longer or shorter due to thermal mass of your parts and your heating ramp rate. Pretesting is recommended to confrm adequate cure for your application, For primerless adhesion products, cure time is based on time to reach durometer. Full adhesion may take more time at the cure temperature.
