Master Bond EP29LPAOHT is a two-component, NASA low-outgassing approved epoxy system with a long working life (8-10 hours per 1,000 gram batch). Due to its low exotherm and flowable consistency, this product is suitable for specialty potting applications where large masses of the epoxy must be cured.
It can be mixed and poured in volumes of more than a gallon at one time. Even in deep cross-section thicknesses, the adhesive generates very little heat. Since the epoxy does not gel quickly, it’s especially useful in production environments that require a long open time after mixing.
EP29LPAOHT offers a high thermal conductivity value of 0.87-1.15 W/(m•K), and is electrically insulative with a volume resistivity of more than 1015 ohm-cm. It has a 100 to 50 mix ratio by weight and a mixed viscosity of 10,000-30,000 cps.
Upon curing EP29LPAOHT exhibits low shrinkage, dimensional stability, and a low coefficient of thermal expansion. Other noteworthy properties include a compressive strength of 24,000 to 26,000 psi, a Shore D hardness of 80 to 90 and a tensile modulus of 450,000-500,000 psi.
This epoxy is serviceable over the wide temperature range of -60° to +350° F.
EP29LPAOHT bonds well to a variety of substrates including metals, glass, ceramics, and many different plastics. It resists many chemicals including, but not limited to, water, fuels and oils. It is available for use in a half-pint, pint, quart, and gallon container kits. EP29LPAOHT does not contain solvents and is RoHS compliant.
