Conformal Coatings

Conformal Coatings Product Families

Dow Corning® Conformal Coatings are supplied in three product families.  Each group is balanced to combine as many of the ideal characteristics as possible but targeted for specific needs.

One of the initial considerations in selecting a silicone conformal coating is the desired cured surface characteristic of the material. RTV Elastoplastic Coatings cure with tougher, more abrasion resistant properties. Due to their physical form, they are supplied in solvent with the newer versions being low VOC. These coatings can be cured at room temperature or, after a short time at ambient to evaporate the solvents, can be heat accelerated to speed processing.

If stress relief is a primary need, Dow Corning also offers silicone conformal coatings that cure with a rubbery, elastomeric surface, RTV Elastomeric and Solventless Heat Cure Coatings. These materials are solventless with both room-temperature and heat-accelerated cures.

RTV Elastomeric Coatings need moisture from the atmosphere to cure.  The family of coatings is rapidly gaining popularity due to its environmentally friendly and solventless formulations, its rapid cure rates that can be dramatically accelerated by mild heat and its cost effectiveness.  These elastomers, when cured, offer the optimum stress relief for components and interconnections in a variety of service environments.

Solventless Heat Cure Coatings are designed for rapid processing at moderate temps (above 100C).  They do require some heating in order to cure and offer long bath life at room temperature.  Like the room temperature curing elastomers above, these products offer the optimum stress relief for components and interconnections in a variety of service environments.  This product line also features coatings that are manufactured for controlled volatility.

RTV Elastoplastic Coatings have firm, dry surfaces for better handling and abrasion resistance and like other RTV materials they need moisture from the atmosphere to cure.  Their cure rates can be accelerated by mild heat being applied after the solvent has dried.  They are supplied in solvent with low VOC versions available.

Dow Corning is continuously expanding the product offerings in each of these families to insure that there are specific products to meet your needs.  For more detail on specific products, go to the Product Finder tool.
