(Summary description)Graphene has hydrophobicity, conductivity and flaky structure. It is used in coatings and coated on substrates to form a dense and strong network to isolate moisture from the coating and reduce the contact between water vapor and the substrate. Graphene is conductive. It also plays a role in cathodic protection. The multi-pronged approach makes the protective performance of graphene coatings more than 5 times higher than that of ordinary coatings.

Graphene has hydrophobicity, conductivity and flaky structure. It is used in coatings and coated on substrates to form a dense and strong network to isolate moisture from the coating and reduce the contact between water vapor and the substrate. Graphene is conductive. It also plays a role in cathodic protection. The multi-pronged approach makes the protective performance of graphene coatings more than 5 times higher than that of ordinary coatings. There are more and more friends who want to know about graphene heat dissipation coatings. As far as the graphene heat dissipation coatings currently under research and development are concerned, the application of graphene in coatings has indeed solved many problems of heat dissipation and heat conduction of metal devices for many enterprises.

Heat conduction and heat dissipation problems of metal components:

At present, the amount of heat-dissipating coatings in the industry is large, but the coatings that can both prevent corrosion and heat dissipation are rare. The existing thermal-conductive coatings often have poor anti-corrosion performance, resulting in corrosion and loss of metal heat-dissipating equipment in the industry. It even has to be repaired or replaced two or three times a year, which seriously reduces the production efficiency and increases the production cost.

Advantages of graphene thermal conductive coating:

The WJ-5076 graphene thermal and heat-dissipating coating developed by Vigon Materials Technology through a special process is coated on the metal workpiece. The graphene and other thermal-conducting materials in the paint film are evenly distributed in the paint film, reducing thermal resistance and increasing thermal conductivity. Effect, the thermal conductivity of thermally conductive coatings added with graphene is greatly improved than that of ordinary thermally conductive coatings, which can reach 20w/m.k. In addition, graphene thermally conductive coatings also retain good mechanical properties, excellent anti-corrosion properties, and the coating is environmentally friendly. Non-toxic paint, conducive to sustainable development.

Graphene thermal conductivity coating application:

Graphene thermal conductive paint is widely used and can be used for various metal components, such as electronic and electrical components, LED lamp shades, radiators, generators, automotive components lamps, etc.

Graphene thermal conductivity and heat dissipation coating features:

Graphene water-based dispersion technology: Disperse high-quality graphene in water-based resin to prepare water-based thermal radiation coatings

High infrared thermal emissivity: infrared thermal emissivity up to 0.95

Excellent heat exchange efficiency: the heat radiation effect is increased by more than 10 times, and the heat transfer efficiency is increased by 70%~80%

Good mechanical properties of the coating: adhesion level 0, resistance to thermal shock at -20℃~150℃

Good temperature resistance: up to 300 ℃, no shedding, no yellowing, no cracking after long-term use

Various construction methods: suitable for spraying process, but also dip coating, scraping coating, brush coating and roller coating

A wealth of optional substrates: common metal, ceramic, and plastic substrates can be constructed
