FS5000 special sealant for solar cell modules
1. Product description
The special sealant for solar cell modules is the use of moisture in the air to cure at room temperature, mainly used for bonding and sealing in the solar photovoltaic module manufacturing industry.
Second, product characteristics
◆ Single component neutral curing at room temperature, small volatility, electrical insulation performance; Good adhesion to aluminum, glass, TPT/TPE backing material, junction box plastic PPO/PA;
◆. Resistance to yellowing, after 85℃ aging test, the colloidal surface did not see obvious yellowing;
◆. Curing system, solid into a soft rubber body, protect components from mechanical vibration and external impact. Through ring test, it has good compatibility with all kinds of EVA;
◆. Flame retardant performance reaches UL 94-V0 level. Comply with the requirements of EU ROHS Directive

4. Methods of use
◆ Determine the base material
The substrate surface should be kept clean and dry. Remove rust, dust and oil.
◆ Sizing
According to the size of the bonding surface and the gap, cut the extrusion nozzle and squeeze it out evenly. The coating amount is controlled by the size of the extrusion nozzle hole. It is appropriate to slightly extrude a rubber ring after the combination of the bonding surface. After the joint surface is coated with a gasket, it is quickly combined and fastened.
