Master Bond Polymer System EP15 is a one component heat curing epoxy featuring high tensile strength that is utilized in testing the adhesion or cohesive strength of flame-sprayed coatings. This standard test is fully detailed in ASTM specification C 633. EP15 is formulated to cure at temperatures from 300°F to 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. Service temperature range is -60°F to 400°F.

As a one component epoxy, Master Bond Polymer System EP15 is easy to handle as it does not require mixing prior to use and has an unlimited working life at room temperature. It bonds well to a wide variety of substrates, but most pertinent is its exceptionally good adhesion to metals and ceramics especially those that are flame-sprayed. The standard color is tan. Although primarily used in the flame sparyed coating test, EP15 can also be utilized in any bonding application where high tensile strength is a prerequisite.
