One Component Epoxy

Master Bond EP5TC-80 is a one part, NASA low outgassing rated epoxy that achieves a thermal conductivity of 3.3-3.7 W/(m·K), while also retaining its electrical non-conductivity. It requires a cure at only 80°C for 1.5 to 2 hours. To optimize performance properties a post cure of 1-2 hours at 80°C is recommended. Featuring a thixotropic paste consistency, this compound adheres well to a variety of substrates such as metals, composites, glass, ceramics, and many plastics. It is formulated for bonding, sealing and small encapsulating applications.

EP5TC-80 is electrically insulating, with a volume resistivity greater than 10¹⁴ ohm-cm. It features a low thermal resistance of 6-10 x 10^-6 K·m²/W and can be applied in very thin sections due to its ultra-fine particle filler. This high strength system has a tensile modulus exceeding 1.5 million psi, and a compressive strength ranging between 25,000 and 27,000 psi.

EP5TC-80 exhibits good dimensional stability with a low shrinkage upon cure, a Shore D hardness of 90-100, and an elongation of 0.5 to 1.5%. It is serviceable over the temperature range of -50°C to +150°C and has a glass transition temperature of 110-115°C. Packaging is available in 3 cc, 5 cc, 10 cc and 30 cc syringes and ships in dry ice.

Master Bond EP4CL-80Med is a one part, optically clear epoxy developed for use in medical device assembly applications. It withstands repeated sterilization cycles and passes ISO 10993-5 testing for non-cytotoxicity. This product cures at moderate temperatures of around 80-85°C within 60 to 90 minutes and faster at slightly higher temperatures. As a one part, non-premixed and frozen system, it contains no solvents, and has an “unlimited” working life at room temperature. Suitable for bonding, sealing, impregnating, and coating, it provides a high glass transition temperature of 155-160°C and has an extremely low viscosity of 50-150 cps at 25°C. This allows it to be applied by brushing, spraying, and spin coating.

EP4CL-80Med provides notable strength properties including a compressive strength of 12,000-14,000 psi and a high tensile modulus of 450,000-500,000 psi at room temperature. It is serviceable over the temperature range of -62°C to +232°C. This compound is an excellent electrical insulator with a volume resistivity of more than 10¹⁴ ohm-cm at room temperature and has a refractive index of 1.52 at 25°C. EP4CL-80Med has good resistance to many sterilization methods, including autoclaving, dry heat, radiation, and chemical sterilants. Furthermore, it resists vaporized hydrogen peroxide, a sterilization technology from STERIS®. It bonds well to a variety of substrates such as metals, composites, ceramics, and many plastics. Packaging is available in jars and cans, as well as syringes.
