Master Bond launches Master Bond EP51CC, a two component, fast setting epoxy with a color-coding system where Part A is white and Part B is black. The two parts combine into a uniform gray color paste, which indicates proper mixing. The fast curing, non-drip compound is ideal for bonding and sealing applications with a forgiving mix ratio of one to one by weight or volume.
Suitable for Cryogenic Applications
Master Bond EP51CC has a rapid set up time, convenient handling, and good physical properties. The high-performance epoxy sets up quickly at room temperature, with a working life of 3-5 minutes for a mixed 50-gram batch. The exact fixture time in an application context can vary from a few minutes to several hours, depending on multiple factors including, but not limited to the size of the components, the substrates being bonded, curing temperature and the amount of adhesive applied.
Master Bond EP51CC’s cure schedule plays an important role in bond strength. For example, it offers a lap shear strength of 700-800 psi when cured at room temperature for 24 hours, but when cured at room temperature for 8 hours followed by 3 hours at +250°F, its lap shear strength increases to 2,300-2,500 psi.
Master Bond EP51CC features high-strength bonds to a variety of substrates including metals, composites, glass, ceramics, vulcanized rubbers, and many plastics with a tensile modulus of 100,000-150,000 psi at room temperature. Master Bond EP51CC is electrically insulative with a volume resistivity of >1014ohm-cm and a dielectric strength of 450 volts/mil.
Formulated for temperatures ranging from 4K to +250°F, the epoxy is also suitable for challenging cryogenic applications. Master Bond EP51CC is available in ounce kits, half pint kits, pint kits, quart kits, gun applicators, and FlexiPaks® for ease of use.
