Descrizione dei prodotti
Coace® R2120 è un copolimero etilene-acetato di vinile funzionalizzato con silano, con un alto contenuto di silano, un'elevata trasparenza e un basso punto di cristallo.
Advanced compounds called silane grafted EVA (Ethylene Vinyl Acetate) photovoltaic film additives are made to improve the characteristics and output of EVA-based solar films.For EVA-based solar modules, silane grafted EVA photovoltaic film additives provide a number of benefits and improved performance. Their special qualities—like better adhesion, crosslinking, and interfacial properties—help to increase the long-term stability, durability, and encapsulation performance of materials.

Dosaggio suggerito：Il dosaggio suggerito èIn base all'applicazione effettiva, tenendo conto dei costi, l'importo appropriato di aumento o diminuzione.
- Improved adhesive: The PV modules’ long-term durability and dependability are guaranteed by the silane grafting process, which strengthens the adhesive between the EVA film and other components like encapsulants or substrates.
- Crosslinking Efficiency: By encouraging effective crosslinking of the EVA matrix, these additives enhance the material’s mechanical strength, resistance to environmental influences, and dimensional stability.
- Crosslinking Efficiency: By encouraging effective crosslinking of the EVA matrix, these additives enhance the material’s mechanical strength, resistance to environmental influences, and dimensional stability.
- UV Resistance: Silane grafted additives provide exceptional UV resistance, reducing the possibility that the EVA film would yellow, discolor, or degrade after extended exposure to sunlight.
- Moisture Barrier: By improving the EVA film’s moisture barrier qualities, the additives lower the chance of moisture intrusion and possible PV module performance deterioration.
Vantaggio
Better Power Conversion Efficiency: These additives’ improved adhesion and crosslinking efficiency lead to better power conversion efficiency, which raises the amount of electricity produced.
Extended Durability and Longevity: The PV modules’ resilience to UV rays, enhanced adhesion, and moisture barrier qualities contribute to their extended durability and longevity, guaranteeing dependable performance throughout their operational lives.
Increased Mechanical Strength: Silane-grafted EVA additives strengthen the EVA film’s mechanical strength, lowering the possibility of module breakage and boosting resistance to mechanical stress during setup or use.

Applicazione
The solar energy sector has a broad range of applications for silane grafted EVA PV film additives.
Encapsulant Films: By adding the additives to the encapsulant, encapsulant and PV cells will adhere better, leading to dependable encapsulation and effective electrical performance.
Backsheets: Silane grafted EVA additives are used in backsheet films, where they improve PV cell adherence and offer superior resistance to moisture and environmental stress.
Lamination Sheets: By using these additives in lamination sheets, the encapsulation process may be facilitated and the integrity and long-term performance of the PV modules can be guaranteed.
