OCTOBER 30, 2009 -- Master Bond UV10TK40 is a UV-curable, no-mix epoxy resin system with enhanced sealing and gap-filling properties. It is appropriate for applications such as aligning parts and bonding irregularly shaped surfaces, especially in production environments where increased speed and reduced waste are critical. Its high surface hardness (Shore A >75) also makes it an option for clear coating.
UV10TK40 is easy to apply and has a viscosity of 35,000-45,000 cps. In addition to the company's standard packaging, UV10TK40 is also available in ready-to-use syringe applicators. The system contains no solvents or other volatiles and is 100% reactive.
The compound is not oxygen inhibited and cures rapidly in the presence of air upon exposure to UV light at room temperatures. It forms highly durable bonds with a typical tensile strength of 8,300 psi, a Young's modulus of 245,000 psi, and an elongation at break of 6%. It has good dimensional stability and high heat stability (94°C Tg).
