Master Bond Polymer System EP21HT is a two component, room temperature curing epoxy adhesive, sealant and coating featuring a forgiving 1 to 1 mix ratio and high temperature resistance up to 400°F. EP21HT produces high strength, durable bonds that hold up well to thermal cycling and resist many chemicals including water, oils, fuels, acids, bases and salts. It bonds well to a variety of substrates including metals, glass, ceramics, wood, rubbers, and many plastics. Once cured, EP21HT possesses superb physical strength properties along with it being an excellent electrical insulator. The cured adhesive fully meets the requirements of MIL-A-81236 (OS) and MMM-A-187B among others. In addition, it meets FDA requirements for food compatibility. While the standard color of the cured material is amber-clear, a wide variety of additional color choices are also available. A non-drip or paste version called EP21HTND is also available.
