SD6105 two-component flame retardant thermal conductive potting compound 1:1, automotive electrical potting protective sealant

Product model: SD6105B two-component flame retardant thermal conductive potting glue

Characteristics: Two-component flame-retardant thermally conductive potting glue is a two-component cross-linked product that is cross-linked through an addition reaction and cured into a high-performance elastomer. The cured elastomer has excellent electrical properties and is resistant to high and low temperatures, media, and aging. Excellent performance. It has good high temperature resistance and bonding performance, is waterproof and moisture-proof, has good deep curing, and does not corrode the bonded material itself or pollute the surrounding environment.


Two-component flame retardant thermal conductive potting adhesive implementation standards

Comply with GB 33372-2020 (VOC) volatile organic compound certification, REACH EU testing standards, the company has passed the flame retardant grade UL certification E358706, ISO14001:2015 certification, ISO9001:2015 certification, cited standard: HG/T3947-2007 single component Room temperature vulcanization requires silicone adhesive/sealant. Through national high-tech enterprises. Our products have passed 1000 hours of hot and cold shock test, 1000 hours of double 85 (high temperature and high humidity) test, and 1000 hours of high temperature aging test. We are committed to providing reliable thermal conductivity solutions for the automotive, communications, security and other industries.


Application scope of two-component flame retardant thermal conductive potting glue

Automotive electrical appliance potting protection sealant is used for potting protection of general electronic components, power modules and printed circuit boards, waterproof, moisture-proof, high voltage resistance; and potting of automotive appliances and various electronic appliances.

How to use and precautions for flame retardant thermally conductive potting glue

Weighing: Accurately weigh components A and B, and mix thoroughly according to the ratio of 1:1 (mass). Before weighing, components A and B should be stirred separately to evenly disperse the settled filler into the glue liquid. , so as not to affect the colloidal properties;

Mixing: Mix the rubber thoroughly and evenly by hand or machine so that the rubber has a uniform color. When using the manual glue filling process, be careful not to add too much glue at one time, otherwise the fluidity will be reduced later and it will be difficult to fill the glue;

Degassing: It is recommended to place the evenly mixed rubber material in a vacuum cabinet for degassing, and use vacuuming to remove the air entrained during the mixing process;

Potting: Pour the bubble-free glue into the device to complete the potting operation. The surface of the device and the mixing container should be kept clean and dry before potting.

Curing: Curing the potted device at room temperature. The viscosity of the mixed colloid will gradually increase over time, so care should be taken to control the potting within the operable time.


This product is non-dangerous, but please keep it out of your mouth or eyes.

Store in a cool, dry place away from rain and sunlight. The shelf life is six months under unopened conditions at 26°C.

This product cannot be mixed with other types of colloids!
