EP15: Utilized to test the bond strength of thermal spray according to ASTM C633

Master Bond EP15 is a one-component, thermally-curing epoxy with a tensile strength in excess of 12,000 psi (82.7 MPa) due to the formation of rigid, dimensionally stable bonds upon curing. This bulk tensile strength makes it ideal for testing the ad …

Product Description

Master Bond EP15 is a one component, heat curing epoxy featuring high tensile strength. It is utilized in testing the adhesion and cohesive strength of ceramic flame sprayed coatings. This standard test is fully detailed in ASTM specification C633. EP15 is formulated to cure at temperatures from 300-350°F for 60-90 minutes. Upon cure, EP15 has a tensile strength well in excess of 12,000 psi. EP15 forms rigid and dimensionally stable bonds with minimal shrinkage upon cure. It is 100% reactive and does not contain any solvents or diluents. Its service temperature range is -60°F to +250°F.

As a one component epoxy, EP15 is easy to handle as it does not require mixing prior to use. Its working life at room temperature is unlimited because it is not premixed and frozen. It has very low shrinkage upon curing and superior dimensional stability. The standard color of the epoxy is tan. Although primarily used in the flame sprayed coating test, EP15 can also be utilized in any bonding application where high tensile strength is a prerequisite..
