Electronics Production / Materials epoxy epoxy system systemMASTER BOND EP35SP two-part epoxy system for bonding and sealing applications, provides resistance to many chemicals such as oils, acids, bases, water, fuels, and especially petrochemicals. Product delivers both a high glass transition temperature (Tg) and a broad service temperature range. Product’s Tg measures 215-220°C and its serviceability extends from -62°C to +288°C (-80°F to 550°F). Product has notable dielectric properties with a dielectric constant of 4.5 at 60Hz and a volume resistivity greater than 1014 ohm-cm. It bonds well to a wide array of substrates including metals, several plastics, ceramics, glass and composites. Upon curing, this system provides low shrinkage and good dimensional stability. Product’s tensile modulus is 550,000-600,000 psi with an overall superior physical strength profile even under adverse environmental conditions.
