Master Bond launches Master Bond EP17TF, a one-part epoxy with a paste consistency, that can be readily dispensed evenly and uniformly. It has a moderately high glass transition temperature (Tg) of 150-155°C and a wide service temperature range from -150°F to +550°F.
Master Bond EP17TF is designed to compensate for thermal mismatches. The product resists impact, vibration, shock and rigorous thermal cycling.
Maintains Electrical Insulation at High Temperatures
Master Bond EP17TF is a reliable electrical insulator, possessing a volume resistivity greater than 1015 ohm-cm and a dielectric constant of 4.5 at 60 Hz at room temperature. It maintains its electrical insulation properties, even at higher temperatures.
The system has good toughness with an elongation of 5-10%. Master Bond EP17TF exhibits superior strength properties, bonding well to similar and dissimilar substrates such as metal, ceramics, plastics and composites. It offers a high lap shear strength of 3,200-3,400 psi, a tensile strength of 8,000-9,000 psi and a tensile modulus of 350,000-400,000 psi at 75°F.
Acids and Solvents Resistant
Master Bond EP17TF requires an elevated temperature cure of 300°F for 5-6 hours, followed by a post-cure at 350°F for 4-5 hours. The additional post-cure is recommended to achieve optimal strength, chemical resistance and thermal properties.
Master Bond EP17TF withstands many chemicals, including acids, bases, fuels, oils and many solvents. It is available in standard packaging from ½ pint containers up to 5-gallon pails. The containers should be refrigerated to extend shelf life.
