Master Bond Polymer Adhesive EP30ND is a high viscosity, two component epoxy adhesive for general purpose bonding and repair formulated to cure at room temperature or more rapidly at elevated temperatures, with a four (4) to one (1) mix ratio by weight or volume. This adhesive is 100% reactive and does not contain any solvents or other volatiles. It is especially recommended where high viscosity is required for ease of application and bonded or repaired assemblies must exhibit superior dimensional stability. Shrinkage after cure is exceptionally low - 0.0003 inches/in. Master Bond EP30ND does not drip sag or run even when applied on vertical or overhead surfaces. It is 100% reactive and does not contain solvents or diluents. Master Bond Polymer Adhesive EP30ND produces high strength and tough bonds which are remarkably resistant to thermal cycling and chemicals including water, oil, fuels and most organbc solvents, oveg the exceptionally wide temperature range of -60°F to more than 250°F. Adhesion to both similar and dissimilar materials including metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent. The hardened material is an electrical insulator. Color of part A is gray, part B slightly yellow. Master Bond Polymer Adhesive EP30ND is widely used for bonding and also to make durable repairs to pumps, pipes, tankage, bulkheads, condenser heads, value bodies and various other equipment in the chemical, construction, marine, automotive and other industries.
