What Is a Thermal Adhesive?

Thermally conductive adhesive is a single component, thermally conductive, room temperature curing silicone adhesive sealant. The condensation reaction of water in the air causes the release of low molecules to cause cross-linking and curing, and vulcanization into a high-performance elastomer. Good viscosity thermal adhesive has excellent resistance to cold and heat alternating performance, aging resistance and electrical insulation properties. And has excellent moisture resistance, shock resistance, corona resistance, leakage resistance and chemical resistance. It can be used continuously at -60 280 and maintain performance. Does not swell and has good adhesion to most metallic and non-metallic materials.

Fast curing speed, easy to extrude, but not flowing, easy to operate, can be applied manually or mechanically, and does not leak, which meets any working environment and conditions, has the advantages of simple and convenient glue application;

It is a non-toxic, non-irritating gas release, solvent-free, non-corrosive, non-polluting, safer and environmentally friendly. It has passed the EU RoHS standard, and at the same time, it can be used by operating conditions operators and consumers of electronic products. Safety and environmental protection provide double protection;

Excellent resistance to high and low temperature, short-term resistance to 300 degrees high temperature, long-term resistance to high temperature 280 degrees, low temperature -60 degrees;

The components of the LED drive module are fixed and fixed to the heat dissipation of the housing; the sizing of high-power LED products, such as high-power LED flood lights, LED street lights, LED power supplies, LED underwater landscape lights, LED point light sources, LED indoor downlights, etc. Adhesives for bonding with brackets, PCB boards and aluminum heat sinks;

Because the glue has strong adhesion to the metal surface, it is not easy to peel off. It is widely used for the adhesion and sealing of PTC sheet and aluminum heat sink, as well as the coating and fixing of plug wires or sheets on the sensor surface;

It is mainly used for heat dissipation between CPU radiator, thyristor, chip and heat sink. The heat dissipation glue of the soleplate of electric iron is used for heat dissipation, the heat conduction of transformer and electronic components are fixed, and then filled.

The thermal conductive glue replaces the traditional card and screw connection;

Thermally conductive adhesives are widely used in industrial production and are called by the majority of users: thermally conductive adhesives, thermally conductive silicones, thermally conductive insulation adhesives, thermally conductive materials, heat-dissipating silicones, LED thermally conductive silicones, and so on.

Ultra-high temperature thermal conductive adhesive, silicone thermal conductive adhesive, epoxy AB adhesive, polyurethane adhesive, polyurethane thermal conductive adhesive, thermal silicone grease.

• Surface treatment: Remove the loose material on the surface of the substrate, and sand it with sandblasting, electric grinding wheel, wire brush or coarse sandpaper to improve the roughness of the repaired surface. Wipe with acetone cleaning agent to clean the bonding surface.

• Glue coating: The repairing agent is composed of A and B two components. When using, strictly mix the main agent A and curing agent B according to the specified mixing ratio until the color is uniform and used up within the specified usable time. The glue cannot be reused;

• Apply the mixed repairing agent to the surface of the treated substrate, apply the force evenly when applying, and repeatedly press to ensure that the material is in full contact with the surface of the substrate to achieve the best effect. When multiple layers of glue are required, the original glued surface must be treated before being applied;

When the temperature is lower than 25 , the curing time can be appropriately extended. When the temperature is lower than 15 , a suitable heat source (infrared, electric furnace, etc.) is used for heating. The surface is 40cm or more, and it is maintained at 60 to 80 ° C for 2 to 3 hours.

• This product is not classified as dangerous goods and can be transported as non-dangerous goods;

• Keep out of reach of children, avoid direct sunlight, store in a cool place;

• Note during construction in summer: when the ambient temperature exceeds 35 ° C, do not mix too much each time, and apply it quickly after mixing;

• If it is difficult to bond special materials, you can apply a thin layer on the surface of the interface with the treatment agent product, and then apply the glue after it is dry;

• If the location of the sizing is deep, especially where it is not easily accessible to air, the time for complete curing will be extended, and if the temperature is lower, the curing time will be extended;

• When the used silicone is used again, if there is a little skin at the seal, it can be used normally as long as it is removed, without affecting the effect of the silicone (but it must be stored in a strictly sealed storage environment);

• Avoid contact with skin or eyes. If contact accidentally, immediately rinse with water and see a doctor. The studio should be well ventilated and wear protective tools if necessary.
