    Typical Features and Advantages of  Thermal conductive silicone Adhesive HC-839W

    This Flame-retardant adhesive is white in color, Paste-like, easy to extrude, easy to apply.

    Good adhesion, capable of adhering to most industrial or daily materials such as metal, plastic, glass, ceramic, alloy, etc.

    It has superior waterproof, moisture-proof, sealing, insulating, shockproof, heat-resistant, and aging-resistant properties.

    This silicone sealant cures into a soft, flexible solid after curing, with good elongation rate, effectively reducing shock and impact protection.

    It surface cures in 3 to 10 minutes, preliminary cures in 4 to 5 hours, and reaches optimal performance in 24 to 72 hours.

    Suitable for flexible adhesive applications requiring thermal conductivity, such as between heat-generating components like chips, switching tubes, LEDs, temperature control probes, batteries, and heat sinks for thermal conduction and flexible bonding applications.

    This silicone sealant is a single-component room temperature curing type, can be directly extruded for application, no need for mixing, high temperature or UV-assisted curing.

    It is convenient to store, can be stored indoors at room temperature without refrigeration. After opening and using, simply tighten the lid for storage until the next use.

    Usage Methods Specifications of Thermal conductive silicone Adhesive HC-839W

    Clean the surface to be coated from dust, oil stains, moisture, and other dirt that could affect adhesion.

    Before use, depending on the required amount, cut open the tip of the nozzle and squeeze out the silicone adhesive, then apply it to the surface to be coated.

    The 100ml tube is typically squeezed by hand, but the silicone adhesive can also be squeezed into the dispensing machine reservoir for application through the dispensing machine.

    For the 300ml and 2600ml sizes, a dispensing gun or dispensing machine is required for application.

    The curing of this silicone adhesive depends on air contact, and the curing process occurs from the surface to the interior. Thus, the greater the contact area with air, the thinner the application thickness, and the faster the curing.

    Low temperature and humidity can slow down the curing speed of the adhesive. In such cases, it the ambient temperature (not exceeding 60°C) and humidity to assist in speeding up the curing time.
