Outdoor Lighting Board Waterproof Insulation Thermal Conductivity Application Case

The original solution was: acrylic.

Pain points: dense, waterproof, insulating, thermally conductive.

1. Two-component materials continue to react over time, poor construction stability.

2. Organic solvent has a big flavor, which is not friendly to the construction environment and workers' health.

3. Insufficient film-forming densification

Test requirements:

1, construction process viscosity 8h change of less than 10%, measure the viscosity of the material from 0-8h per hour, rotating viscometer OR painted 4 cups, etc..

2, weather resistance: 6090-240h, double 85-240h, hot and cold punch -40 ~ 80 100 cycles.

3, drying film toughness: coated on PET to form a film, drying and curing to observe whether the coating film will crack.

4, transmittance and gloss: after the film is formed, test the film transmittance and gloss.

5、Conductivity: Test the contact resistance and insertion resistance of the film after it is formed, which is more than 10MΩ.
