ITW Devcon® Tru-Bond™ LOCA 5000 Coating
Categories:	Polymer; Thermoset
Material Notes:	Devcon® Tru-Bond™ LOCA products are high clarity, fast curing, UV light curing products. They are engineered to eliminate the air gap between the cover lens of touch panels and display devices. These liquid dispensed, ultra-low hardness products help reduce stresses that contribute to Mura while helping to increase the impact resistance and durability of the assembly. Cure as tested: LED 365 lamp, illumination intensity= 150mV/cm², total energy 1500 mJ/cm² Information provided by ITW Performance Polymers.
