72923: High-Performance Solution for UV Peelable Protective Coatings

In the realm of temporary protection materials, balancing yellowing resistance with curing speed has long been an industry challenge. Model 72923, a cutting-edge Polyurethane Acrylate Resin, is specifically engineered to solve this paradox for UV peelable adhesive formulations.

Designed for manufacturers demanding efficiency and quality, 72923 delivers an ultra-fast reaction speed, drastically reducing production cycle times. Its standout feature is the excellent yellowing resistance; even after prolonged UV exposure or heat aging tests, the cured film remains crystal clear. This makes it the perfect choice for optical-grade applications such as mobile phone covers and touch screens where aesthetics are paramount.

Beyond clarity and speed, 72923 offers a unique combination of high tensile strength and high elongation. This superior flexibility ensures that the protective mask can be peeled off in one complete piece without tearing, leaving zero residue on the substrate. It provides robust protection during processing and logistics while guaranteeing a pristine surface upon removal.
