UV-curable PSA from CS chemical is a process protection tape that has excellent thermal stability and is easy to remove. The existing tape of process protection has a problem that the latter adhesive Strength is higher than the initial adhesive Strength due to pressure and high temperature during processing, and a lot of force is required to remove the adhesive film. However, the protective tape of CS chemical has a low adhesive strength after UV irradiation and is easily peeled off, and after peeling, no tape residue remains on the Substrate.

In the conventional technology, since oligomers or multifunctional monomers are blending with photoinitiators to induce UV curing, weathering and heat resistance are very poor due to migration of unreacted oligomers or multifunctional monomers. CS chemical’s technology does not a simply blending, but attaches a double bond to the polymer chain as a chemical bond, so there is no deterioration in weather resistance and heat resistance due to migration. For this reason, it can be applied to the protective tape for processes requiring high temperature and high pressure. In particular, it shows excellent properties when applied to stainless steel.
