The manufacturer of coated paper tells you that coated paper is made of plastic particles coated on the surface of composite materials through a casting machine. The main characteristics of this composite material are that it can be oiled (relatively), waterproof (relatively), and heated. The technical indicators of coated paper are: dry silicon coating amount, room temperature peeling force, aging peeling force, and residual adhesion. The amount of dry silicon coating refers to the amount of release agent applied to a material with a unit of g/m2, which is generally 0.30 ー 0.80 g/m2 for solvent based silicone oil and 0.80 ー 1.30 g/m2 for solvent free silicone oil. Professional testing equipment is required to test the coating amount. The amount of silicone oil coating directly affects the peeling performance. High coating amount, can tightly adhere to the original paper, ensuring uniform distribution of silicone oil. However, due to the low amount of silicone oil coating, it is easy to experience coating defects, leading to poor peeling. In order to reduce the amount of silicone oil coatings used by some suppliers, resulting in peeling weight, there is a considerable risk in the production of heavy-duty release paper. Adjusting the release force through chemical formulas requires a long time, rather than overnight. The peeling force at room temperature is measured in n/25 millimeters as a standard peeling force and can be converted into grams.

It is generally {{0}}.10 n/25mm, which means that the peeling force below 10g is generally referred to as light peeling force, 0.20 n/25mm, which means that the peeling force below 20g is generally referred to as medium peeling force, 0.35 n/25mm, which means that the peeling force is 35-45g, commonly known as weight peeling, 0.60-0.80 n/25mm, which means that the peeling force is 60-80g, commonly known as weight peeling; Of course, there are 0.03~0.04 n/25 millimeters, which is the peeling force of 3-4 grams, commonly known as light peeling; There is 1.00 n/25mm, which means the peeling force exceeds 100 grams, commonly known as overweight peeling. The measured value of peel force after aging is generally greater than the measured value of peel force at room temperature. The remaining adhesion ratio is the force exerted on the release paper after the first and second peelings. The results mainly reflect the curing effect of silicone oil. The residual adhesion rate of UV cured silicone oil is generally 100%, and the maximum residual adhesion rate of thermosetting silicone oil is 90%. If a few suppliers claim that their residual adhesion rate of release paper is 100%, it is suspicious. If silicon is removed, the residual adhesion rate of this release paper generally does not exceed 70%.
