The difference between solvent-free release film and solvent release film-film supplier

by：POLYVA 2022-01-31

The coating cost of solvent-based silicone oil is low. For example, oil glue K-50, dry glue 60 grams, the coating amount of solvent-based dry silicone coating is 0.80 grams per square meter, if you use solvent-free dry silicone coating The amount of cloth must be 1.30 grams per square meter. Due to equipment limitations and in order to reduce coating costs, many release coating suppliers have added solvents to solvent-free silicone oils to reduce the content of silicone and reduce the amount of coating. The risk is considerable. Moreover, solvent-free silicone oil is not suitable for oil glue. Silicone oil needs to be volatilized and weathered at a certain temperature, so thermal curing silicone oil is mostly used at present. Of course, many domestic companies have already used UV curing, mainly for film coating. Because the film cannot tolerate the curing temperature, UV curing is generally used, which is a relatively expensive curing method, regardless of equipment investment or processing cost. UV curing is one to two times of thermal curing.
