Master Bond adhesives
Armstrong A-12 Epoxy Adhesive, at 1:1 Mix Ratio
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Our most popular general-purpose, high viscosity adhesive for industry. Combines low toxicity with excellent physical properties, and offers a non-critical mixing ratio of 1:1 by weight. This ratio can be altered to achieve improved bond properties at elevated or cryogenic temperatures. Adhesive and curing agent are easily mixed and are of different colors for visual assurance of thorough mixing. A-12 meets the requirements of Mil Spec. MIL-A-47074 (MI) Type 1, Class 2.
