PRO-SET Laminating Epoxies are a versatile system of liquid resins and hardeners designed to meet a wide range of wet lay-up laminating applications.
STANDARD LAMINATING SYSTEMS
Any Standard PRO-SET Laminating resin may be combined with any PRO-SET Laminating hardener to create a "custom" epoxy blend. PRO-SET Laminating hardeners range from fast to extra slow and may be blended to provide even greater versatility with your custom processes.
Choose resin by viscosity and hardener by speed. To simplify the choice, Standard PRO-SET Laminating resins and hardeners are priced the same (except for High-Temp).
Use PRO-SET Laminating Epoxies to produce lightweight, highperformance composite structures that will withstand long-term cyclic loading in the harshest environments. These epoxies bond to core materials, wood, metal and all reinforcing fabrics. They offer excellent moisture resistance, toughness and superior resistance to heat and fatigue. PRO-SET Laminating Epoxies develop excellent physical properties at room temperature and may be post-cured for enhanced performance.
Laminating Epoxies can by dyed, upon request, to provide for visual quality control. A yellow dye in the resin and a blue dye in the hardener, when properly metered and thoroughly mixed, will result in a consistent shade of green.
