What are the technical indicators of coated paper?
Jun 25,2024
The technical indexes of coated paper are as follows: dry silicon coating amount, normal temperature peeling force, aging peeling force and residual adhesion rate.
The dry silicon coating weight refers to the amount of release agent coated on the material, and the unit is grams per square meter. Generally, the coating amount of solvent-based silicone oil is from 0.30 to 0.80 grams per square meter, and the coating amount of solvent-free silicone oil is from 0.80 to 1.30 grams per square meter. Professional testing equipment is required to test the coating amount. The coating amount of silicone oil directly affects the peeling performance. The high coating amount can cover the base paper tightly and ensure the uniform distribution of silicone oil. The lower the amount of silicone oil coating, it is easy to appear the phenomenon of leakage, resulting in poor peeling. Some release coating suppliers to reduce the amount of silicone oil coating, resulting in peeling bias, the production of heavy release paper, in the use of a considerable risk. The reliable manufacturer realizes the adjustment of the peeling force through the adjustment of the chemical formula without reducing the coating amount of silicone oil. This is a long time to accumulate technology, rather than overnight.
