Featuring a thick paste consistency, Master Bond EP21NDFG bonds well to a variety of substrates including metals, composites, glass, ceramics and many types of rubbers and plastics. The epoxy is truly non-drip and will not run or sag, even when applied to vertical surfaces. It produces high strength, durable bonds that resist thermal cycling as well as chemicals including water, oils, fuels, acids, bases and salts. The product is a two component, room temperature curing epoxy that has a non-critical one to one mix ratio by weight or volume. It also has the unusual characteristic of being able to adjust the properties of the cured system by altering the mix ratio. Adding more of Part A (e.g. 2:1 mix ratio) will give a more rigid cure, while adding more of Part B (e.g. 1:2 mix ratio) gives a more forgiving cure. Once cured, the epoxy is an electrically insulative system. It is serviceable over the wide temperature range of -60°F to +250°F. The color of both Parts A and Part B is amber, although, a wide variety of additional color choices are also available. Passing FDA Section 175.105 tests, the product is primarily used in food equipment applications where there is an indirect exposure to food and related products.
