Huitian 9761 RTV high-strength adhesive sealing thermal conductive silicone

9761 RTV high-performance adhesive sealing silicone rubber is a single component, white paste de alcoholized, flame-retardant and thermally conductive room temperature vulcanized silicone rubber. The cured adhesive layer is an elastic material; After solidification, alcohol substances are released, which are non corrosive to the vast majority of metals; The content of small molecules is less than 300ppm; It has excellent weather resistance, moisture resistance, and heat resistance, as well as excellent adhesive properties, and has good adhesion to most metals, plastics, ceramics, and glass.

typical use

TV、CRT、 Mechanical bonding and sealing of electronic and electrical components such as power supplies and communication equipment, as well as adhesive fixation of electronic components. Adhesive sealing of other metals, plastics, glass, etc. that require flame retardancy and thermal conductivity.

Instructions for Use

Clean the surface: Clean the surface of the object to be glued, removing rust, dust, oil stains, etc.

Glue application: Squeeze the glue onto the cleaned surface.

Curing: Place the glued component in the air, and after the skin is formed, tighten it tightly

Next is the solidification process from the surface to the interior. After curing for 24 hours at 25 ℃ and 55% relative humidity, the curing depth of the adhesive is 2-4mm, and the curing depth gradually increases with time.

Storage: Unused glue should be immediately sealed and stored in the cap or in the equipment pressure plate, and the glue outlet should be sealed and stored in silicone oil. When reusing, remove a small amount of skin from the adhesive outlet without affecting normal use. During the storage process, there may also be a small amount of solidification at the mouth of the adhesive. After removing it, it can be used normally without affecting the product performance.

Precautions

Keep away from children.

It is recommended to use it in a well ventilated area to reduce odors.

If accidentally in contact with the skin, wipe it clean and then rinse with clean water; If it accidentally comes into contact with the eyes, immediately rinse with clean water and go to the hospital for examination.

Please refer to the MSDS of this product for safety information.

Storage conditions

Store in a cool and dry place at 8-28 ℃.

The storage period is 6 months.
