Silicone sealant:
1)Can bond to alumium and TPT/TPE strongly.
2)The color is not changed under the sun light and the rain.
PT1518 Silicone sealant for solar panel
It is a one-component room temperature curing silicone rubber (solar panels, special plastic), can improve the reliability of sensitive circuits and components to extend service life. Insulation, shock absorption, impact resistance, operating temperature range (-50 ° ~ +250 °). With the weather resistance, chemical corrosion, heat and so on. Outdoor use may be exempt from UV, ozone, water and the adverse effects of chemicals. Can also be bonded PBT, ABS, PC and other plastics.
1,Characteristics and use:
1)Improve sensitive of circuits and component’s reliability; prolong their service life.
2)Insulation, shock-proof, impact resistant, working temperature range (-50 °C ~ + 230 °C).
3)Weathering resistance, heat resistance and corrosion-resistant.
4)It can resist ultraviolet, ozone, and the harmful effects of water and chemicals.
5)No change in physical and mechanical performance and anti-yellowing after 1,000 hour hrough the"double 85".( the "double 85" means the relative temperature is 850C, relative humidity is 85%.)
6)It can adhesive PBT, ABS, PC plastics.
2,Packing:300 ml plastic tube; 310ml, 500ml or 600 ml flexible packaging.(Can make different color according to requirements and the different packing specifications)
