Two-Component, Room Temperature Cure Adhesives/Sealants and Potting Compounds/Encapsulants
RTV11 (white), RTV21 (pink)– FDA compliant, supplied ready-to-use with a base compound and DBT (dibutyl tin dilaurate) as the standard curing agent. DBT is suitable for most applications, however other catalysts are available to facilitate deep section cure, faster cure, and automated mixing. Composition is free of solvents and solvent odor. RTV11 is FDA compliant and can be used in food contact applications other than contact with acidic foods where FDA regulations apply. Typical applications include rubber molds, formed-in-place gaskets, medical molds, high voltage power supply potting, and general electrical potting.
RTV31 (red), RTV60 (red)– high temperature silicone elastomers supplied ready-to-use with a base compound and DBT (dibutyl tin dilaurate) as the standard curing agent. DBT is suitable for most applications, however other catalysts are available to facilitate deep section cure, faster cure and automated mixing. RTV31 and RTV60 differ primarily in viscosity in the uncured state. RTV31 applications include fabrication of rubber parts, potting and encapsulating electrical motors, transformers, surge protectors, and industrial filters, as well as casting molds for low-melting point metals, rubber rollers, and thermal insulation. RTV60 is good for potting and encapsulation.
RTV511 (white), RTV560 (red), RTV577 (white)– are low temperature silicone elastomers. They are supplied ready to use with a base compound and DBT (dibutyl tin dilaurate) as the standard curing agent. Other catalysts are available to facilitate deep section cure, faster cure, and automated mixing. RTV560 has the widest useful temperature (highest and lowest) of any silicone elastomer from -175°F up to 500°F continuously and up to 600°F for short periods of time. Applications include cast-in-place heat shielding, thermal insulation, and potting and encapsulation of electrical assemblies.
RTV566– silicone rubber compound is a two-part product processed and tested for applications where low outgassing is required. RTV566A base compound is supplied ready to use with RTV566B curing agent. RTV566 has a room temperature cure and excellent release properties. It retains elastomeric properties from -175°F up to 500°F continuously, and up to 600°F for short periods of time. Applications include those with low outgassing, cast-in-place heat shielding, thermal insulation, potting and encapsulation of electrical assemblies.
RTV615 (clear), RTV655 (clear)– are optically clear liquids which cure at room temperature to high strength silicone rubber with the addition of curing agents. These two-component products are supplied with curing agent in matched kits which are designed for use at a convenient 10:1 ratio by weight. These compounds are clear and colorless, low viscosity, and easily pourable. They differ in low temperature flexibility. RTV615 has the capability to remain flexible at temperatures from -75°F to 400°F, RTV655 from -175°F to 400°F. They can be used for protection of electronic components and assemblies against shock, vibration, moisture, ozone, dust, chemicals, and other environmental hazards by potting or encapsulation of the components and assemblies. Clarity permits visual inspection for easy identification and repair of encapsulated parts.
RTV627 (dark gray)– flame retardant, UL V-0, room temperature vulcanizing compound for potting and encapsulation, particularly where flammability is of concern. This product is supplied with curing agent in matched kits which are designed for use at a convenient 1:1 ratio by weight or volume. RTV627 silicone rubber compound has an easily pourable viscosity of about 1300 cps. Applications include production line potting compound to provide protection of electronic components and assemblies against thermal shock, vibration, moisture, ozone, dust, chemicals, and other environmental hazards, encapsulation of high voltage transformers, voltage regulators, power converters, and complete power supplies.
RTV630– blue two component silicone rubber compound cures at room temperature to a high strength silicone rubber. This product is supplied in a matched kit of base (A) component and curing agent (B) component which is designed for use at a convenient 10:1 ratio by weight. The viscosity of the catalyzed compound is a moderately pourable 150,000 cps. This medium viscosity product will form thin, light-weight molds with excellent durability. The high tear resistance and inherent release ability of RTV630 rubber compound make it well suited to the manufacture of intricate castings, by reproducing each part exactly to detail. Other applications include prototype parts, production tools for casting epoxies, and rubber rolls. Electrical circuits requiring a tough potting compound with outstanding vibration withstanding capability find RTV630 unequalled.
RTV664 (beige, blue)– is an addition (platinum) curing mold making product offering high durometer for applications requiring greater dimensional stability. RTV664 is a high durometer (62 Shore A), long work life product. It offers excellent chemical and abrasion resistance and was designed for high production on manufacturing lines.
