Lord Adhesives Thermoset™ DC-80 Thixotropic Epoxy Adhesive
Categories:	Polymer; Thermoset; Epoxy; Epoxy Adhesive
Material Notes:	LORD Thermoset DC-80 adhesive is a paste consistency, epoxy adhesive which may be used in varying proportions of resin to hardener to provide optimum properties for particular applications. Higher levels of hardener produce cured products of increased flexibility. Thermoset DC-80 will provide improved tensile shear and peel strength in the bonding of flexible substrates. Thermoset DC-80 resin is white and the hardener is black. These colors assist as an indicator of a thorough mix when the catalyzed system becomes gray without streaks. The following list of suggested mix ratios (resin:hardener) gives the application and typical cured properties of each: Rigid Bond: 2:1 by weight or 1.7:1 by volume. Bonds metals, glass, ceramics, and most plastics. Best chemical resistance. Can be used in some applications to temperatures of 250°F. Semi-Rigid Bond: 1:1 by weight or 1:1.2 by volume. Improved impact and thermal shock resistance. Higher tensile shear strength than rigid bond. Flexible Bond: 1:2 by weight or 1:2.4 by volume. For bonding hard rubber, teflon and treated polyethylene. Better peel strength than rigid or semi-rigid bond. Within the range of mix ratios from 1:2 to 2:1 (resin to hardener by weight) cured properties can be effected as follows: Increasing the proportion of DC-80 Hardener: Increases flexibility, % elongation; decreases water resistance, heat resistance, acid resistance. Decreasing the proportion of DC-80 Hardener: decreases flexibility, % elongation; increases water resistance, heat resistance, acid resistance. All information provided by Lord.
