Technical Data Sheet
TSE399

TSE399

Description
TSE392, TSE397 and TSE399 adhesive/sealants/coatings are one component RTV's that cure quickly by reacting with atmospheric moisture forming a soft dielectric silicone rubber. These materials incorporate a newly developed crosslinking chemistry and are non-corrosive to metallic substrates. They are particularly well suited for electrical/electronic applications. This series of products differ in consistency, TSE392 is a thixotropic paste, TSE397 is semi-flowable, and TSE399 is flowable. When cured, they retain their elastomeric properties throughout the operating range of temperature from -55C to 200°C (-67F to 392F).
Key Features and Benefits
PRODUCT FEATURES
Meets the corrosion resistant requirements of MIL-A-46146A* Outstanding adhesion, including most plastics Resistant to heat, cold, moisture, UV, ozone and chemicals PRODUCT BENEFITS
One component, no mixing or de-airing required Soft consistency provides protection against mechanical and thermal shock Varying viscosities allow thorough coating around complex assemblies (TSE399) and thicker coatings where required i.e., high voltage components Convenient packaging/dispensing tubes or cartridges. * Does not meet hydrolytic stability requirement of MIL-A-46146A

Product Safety, Handling and Storage
The warranty period is 12 months from the date of shipment from Momentive Performance Materials if stored in the original unopened container at temperatures between 5C and 30C (41F and 86F). Customers should review the latest Material Safety Data Sheet (MSDS) and label for product safety information, safe handling instructions, personal protective equipment if necessary, and any special storage conditions required for safety. MSDS are available at www.momentive.com or, upon request, from any Momentive Performance Materials (MPM) representative. For product storage and handling procedures to maintain the
product quality within our stated specifications, please review Certificates of Analysis, which are available in the Order Center. Use of
other materials in conjunction with MPM products (for example, primers) may require additional precautions. Please review and follow the safety information provided by the manufacturer of such other materials.
Processing Recommendations
Surface Preparation
Insure that surfaces to be sealed, coated or bonded are clean and free of grease, lubricating oils, release agents and dirt. To optimize fast cure and good adhesion, substrates must be thoroughly dry of cleaning solvents before applying the RTV. The RTV should be applied to one surface only. Wipe away excess uncured material with a clean cloth. After curing, removal of material is more difficult. These products offer primerless adhesion to many substrates including most plastics. Maximum adhesion is obtained 72 hours after full cure is obtained (2 mm thick specimen to an aluminum substrate). These products cure at room temperature reacting with atmospheric moisture. Whenever possible, 25°C (77°F) and 50% relative humidity should be provided. Higher temperature and humidity will cause faster cures while lower temperatures and lower humidity will slow the cure considerably. These products cure from the outside (outer skin) inward, therefore, cure rate is also dependent on the thickness of the material. It is not recommended to apply material thicker than 1/4 inch.
