One part epoxy for testing adhesion or cohesive strength of ceramic based flame-sprayed coatings

Key Features

  • Used in ASTM C633 testing applications
  • Exceptionally high tensile strength
  • Excellent dimensional stability
  • Withstands 1,000 hours 85°C/85% RH

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..

Case Studies

Researchers in Canada tested SiC-reinforced Al-12Si alloy coatings that were produced using the Cold Gas Dynamic Spraying deposition process. The composite coatings’ bond strengths and microstructures were evaluated, as well as the porosity and the SiC content. Bond strength evaluations were conducted using the ASTM Standard C 633-01. Master Bond EP15 was used to test a coating that was produced on grit blasted standard test samples. They were then machined flat and glued to an uncoated test sample. The bonding agent was also initially tested separately.1
