One Component Epoxy

Formulated for use in demanding thermal management applications, Master Bond EP30TC is a two component epoxy that contains a robust thermally conductive filler with very fine particle sizes. This NASA low outgassing certified system can be used for bonding, coating, sealing and encapsulating for the aerospace, electronic, optical and OEM industries.

EP30TC exhibits a thermal conductivity of 18-20 BTU•in/ft²•hr•°F [2.60-2.88 W/(m•K)] and has  the ability to be applied in sections as thin as 5-15 microns, resulting in a low thermal resistance of 7-10 x 10^-6 K•m²/W. This compound is a reliable electrical insulator and has a volume resistivity of over 10¹⁴ ohm-cm. It is serviceable over the wide temperature range of -100°F to +300°F [-73°C to +149°C].

EP30TC features a low viscosity with excellent flow properties making it well suited for coating and potting applications. As a two part system, it requires a 10 to 1 mix ratio by weight. Color coding facilitates mixing with Part A being gray and Part B being clear. It can be cured at room or elevated temperatures, but to achieve optimum properties, the recommended cure schedule is overnight at ambient temperature followed by 2-3 hours at 150-200°F.

This system bonds well to metals, composites, ceramics, glass and many plastics. It delivers superior physical strength properties, with a tensile strength of 5,000-6,000 psi, a compressive strength of 24,000-26,000 psi and a tensile modulus of 500,000-550,000 psi. Dimensionally stable, EP30TC also has very low shrinkage upon curing and a low coefficient of thermal expansion.

This product is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits, as well as in premixed and frozen syringes.

Formulated for bonding, sealing, coating and encapsulation applications, Master Bond EP41S-5 is a room temperature curing epoxy that combines a high strength profile, superior electrical insulation values and exceptional chemical resistance. This system can be used in the aerospace, electronic, power, chemical processing, specialty OEM and other industries.

Well suited for coating pumps, tanks, storage vessels and piping, EP41S-5 is able to deliver long-term protection against a wide array of chemicals including acids, bases, alcohols, fuels and many solvents. Most noteworthy is its resistance to methylene chloride, a common stripping agent. This makes EP41S-5 ideal for tamper proofing applications in the electronic industry.

EP41S-5 offers convenient handling with a 100 to 25 mix ratio by weight. The mixed epoxy has good flow properties with a moderate viscosity of 25,000-30,000 cps. It bonds well to a wide variety of substrates including metals, composites, glass, ceramics, as well as many rubbers and plastics. EP41S-5 will cure at room temperature or more rapidly at elevated temperatures. Upon curing, this system is rigid, with a hardness of 85-95 Shore D. It has a tensile strength of 10,000-12,000 psi at room temperature. Additionally, EP41S-5 features reliable electrical insulation characteristics with a dielectric constant of 3.5 at 60 Hz and a volume resistivity greater than 10¹⁴ ohm-cm.

EP41S-5 is serviceable over the wide temperature range of -80°F to +300°F [-62°C to +149°C]. Its natural color is black, but can be formulated in additional colors. This solvent free system is available for use in ½ pint, pint, quart, gallon and 5 gallon container kits as well as double barrel cartridges that can be dispensed in gun applicators.
