AT-TACK, HARU, HD series

Products are designed according to various uses, such as re-peeling type adhesion, highly adhesive products, heat peeling adhesion, multi-layer adhesion, optical properties, UV shield, and others. ​

Polyurethane series OCA & OCR HARU series

Effects of urethane adhesive
1. Does not corrode ITO
2. Problem of bubbles is solved when attaching PC and PMMA
3. Excellent flexibility and has good filling characteristics in the ink gap
4. Good adhesive force from thin coat film to thick coat film

Heat peeling adhesive film HD series

・The adhesive layer is thin and has excellent processing stability
・As the adherence force is strong, work scattering is less and dimension stability is good
・Peels quickly at high temperature
・Peeling temperature can be adjusted according to the requirement

Differential film AB600T series

AB600T-75 is a double adhesive film with excellent optical characteristics. The acrylic strong adhesive layer adheres strongly to glass or PET. The silicone weak adhesive layer adheres smoothly while removing air on the liquid crystal surface of a smart phone or a tablet PC. Peel tape, adjust position, and put it on. This results in a clear screen without air bubbles in only three steps.
