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.
