Resinlab® EP1320 Heat Cure Epoxy Conformal Coating
Categories:	Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive
Material Notes:	Resinlab™ EP1320 and EP1320LV are one part heat cure epoxy conformal coatings. They can also be used as a small mass potting compounds, structural adhesives, or insulating polymer systems where the application requires low shrinkage and excellent adhesion to a wide variety of plastics, metals and circuit board materials. These products give very good environmental protection and dielectric properties over a wide temperature range. The primary difference between the two versions is the LV version has a lower high shear viscosity (higher press flow rate) to provide easier dispensing. The amount of sag upon curing is the same.
