WSD-1740 Optical Pressure-Sensitive Adhesive for Polarizers
- WSD-1740 is a two-component pressure-sensitive adhesive designed for polarizer backing applications.
- It provides very high initial adhesion, excellent yellowing resistance, and strong resistance to damp heat aging.
- After DH 1000 h testing, adhesive shrinkage is less than 0.5 mm, and no adhesive residue remains on the glass surface after peeling.
