Curing Method Comparison
Thermal vs UV Cured Silicone Coated Release Film
The primary differences between clear PET thermal cured and UV cured silicone coated release films lie in curing methods, processing conditions, properties, and applications.
Key Differences
Curing Method: Thermal curing uses heat for cross-linking, while UV curing employs UV radiation for photochemical reactions
Processing Conditions: Thermal curing requires high temperatures, limiting substrate compatibility; UV curing uses lower temperatures for broader substrate range
Properties: Thermal cured offers better dimensional stability and temperature resistance with longer shelf life; UV cured provides superior optical clarity with less yellowing tendency
UV curing is most common in tape applications due to faster curing times, lower energy consumption, and substrate flexibility. However, thermal curing is required for high-temperature adhesive tapes used in automotive and electronics industries where temperature resistance is critical.
Industry Trends
The PET silicone coating industry is shifting toward electron-beam (EB) and UV curing processes due to environmental benefits, faster curing times, better controllability, increased substrate compatibility, and improved cost-effectiveness. While thermal curing remains widely used, EB and UV methods are becoming preferred for many applications.
