Liquid optically clear adhesive (LOCA) is an essential component in the assembly of liquid crystal displays (LCDs). Its unique properties offer a multitude of advantages that enhance the efficiency, accuracy, optical clarity, and overall performance of the LCD assembly process. Among these advantages, the low viscosity of LOCA plays a particularly critical role in ensuring the production of high-quality LCD displays. 

Liquid, optically clear adhesives (LOCA) provide superior optical enhancement and anti-glare properties in the manufacture of liquid crystal displays. The design of LOCA adhesives must take into account long-term exposure to environmental conditions such as light, temperature, humidity, and mechanical shock. Resin Designs chemists have devised a family of products for both screen face adhesion and edge sealing that have been fully tested to assure clarity and adhesion are maintained over time.
