Products Description
Coace® R1120 is a chemical functionalized ethylene copolymer to be used as modifier in photovoltaic encapsulant film.
The adhesion between photovoltaic packaging films and solar silicon crystal panels has a great impact on the yield of photovoltaic panels. The key step to achieve this adhesion is to add photovoltaic packaging film additives. After adding additives, the adhesion between the film and the solar silicon crystal panel will be effectively improved, thereby improving the yield.
In the production of photovoltaic (PV) films, hot melt adhesive is essential because it offers a strong binding between different parts of PV modules. The glue in question is essential to maintaining the longevity and integrity of photovoltaic modules due to its superior adhesion, rapid curing, high temperature resistance, and electrical insulating qualities.
