HY595Thermally Conductive Electronic Neutrall Silicone Adhesive

Jiagu thermal conductive silicone rubber sealant, referred to as RTV-1 sealant, has the advantages of no solvent, no isocyanate, anti-pollution after curing, environmental protection, excellent heat resistance and anti-aging ability. It’s suitable for heat conduction sealing of mechanical equipment and electronic components. This product meets environmental protection requirements, does not contain harmful substances in GB18583 "Limits of Hazardous Substances in Adhesives for Interior Decoration Materials", and complies with EU ROHS and REACH environmental protection standards.

product description

Product Features

1. Excellent thermal conductivity.

2. Solvent-free, PVC-free, isocyanate-free, non-toxic, neutral and environmentally friendly.

3. Excellent thixotropy and extrudability, wide applicable temperature range.

4. It has excellent bonding properties to most metals such as aluminum, painted steel plates and PVC, ABS, and polyester materials.

5. Excellent weather resistance, aging resistance, superior tensile and compression resilience.

Scope of application

Suitable for heat conduction sealing and bonding of various electronic components; HY583H is non-corrosive to materials such as polycarbonate (PC) and copper.

Curing mechanism

Jiagu thermal conductive silicone rubber sealant is a moisture-absorbing curing adhesive. Once the gel is unsealed, the gel absorbs moisture in the air and gradually solidifies from the surface of the gel to the deep layer to become an elastomer. The higher the temperature and the higher the humidity, the faster the curing; the curing speed would be slower in the low temperature and low humidity environment.

Resistant to chemical media

The product can be resistant to fresh water, sewage, waste water, calcium carbonate aqueous solution, detergent, low acid, corrosive water solution, etc. for a long time, and short-term resistant to mineral oil, vegetable oil, fat, fuel, but not resistant to organic solvents, paint thinners, and high-concentration acids Alkali etc.


1. The surface of the joint should be free of oil stains, dust, impurities, etc.

2. Cut the glue nozzle into the required size and shape according to the process requirements;

3. Cut off the sealant seal, install the glue nozzle, and put it into the glue gun;

4. Apply the sealant evenly to the joints, the thinnest part is greater than 1mm; when using a pneumatic glue gun, the air pressure is controlled at 0.2~0.4Mpa;

5. The product can be trimmed using traditional methods after the surface is dry.

Matters Needing Attention

1. Avoid construction under 5℃and humidity less than 20%

2. Pneumatic pressure is strictly prohibited to exceed 0.5 Mpa, if it exceeds 0.5 Mpa, gas will enter the hard packaging tube, and colloidal bubbles will occur.

3. Since the coating contains high solvent content, the glue surface will become soft. In order to obtain the best appearance and performance, apply the glue after painting for 24 hours.

4. For special chemical reactions, please contact our technical department.

Packing Specification

Aluminum tube: 100ml/tube, 100tubes/carton

Hard plastic packaging: 310ml/tube, 50tubes /carton

Storage method

RTV-1 sealant absorbs moisture and solidifies. It must be stored in a low temperature and dry environment. The shelf life is 6 months.

Safety and Health

1. Do not contact uncured sealant products with food and cosmetics;

2. The uncured sealant should not be in contact with the skin for a long time;

3. If the sealant accidentally gets into your eyes, you must immediately rinse with plenty of water, and then ask a doctor for examination;

4. Keep the product out of the reach of children.
