Master Bond EP30M4 is a two part, room temperature curing potting/encapsulation compound with a 100 to 60 mix ratio by weight. Cures can be accelerated by the use of heat. This will optimize the chemical resistance properties of EP30M4. Some of the potent chemicals it can resist include skydrol, xylene, 70% sulfuric acid, 98% sulfuric acid, 50% sodium hydroxide and bleach.
EP30M4 has excellent physical strength properties. It has superior adhesion to similar and dissimilar substrates. Electrical insulation properties are exceptional. Its volume resistivity is > 1014 ohm cm and dielectric constant is 3.71 at 60 Hz. Shore D hardness is 75-85. Additionally, EP30M4 has a tensile strength of > 7,000 psi and a tensile modulus of 350,000-400,000 psi. Shear strength is > 2,000 psi. Service operating temperature range for this compound is -80°F to 300°F.
Master Bond EP30M4 has good flow properties and a moderate viscosity. Working life for a 100 gram mass is 45-75 minutes at 75°F. The color of Part A is clear and Part B is amber. It is available for use in ½ pint, pint, quart, gallon and 5 gallon pail kit containers. This system is widely employed in the electronic, electrical, electro-optical, appliance, automotive, oil/chemical processing and transportation industries.
