Extra-Slow Laminating Hardener - 4.9 Gal (Group Size 3)

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.
Use them to produce lightweight, high-performance 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.

• 150 gm pot life at 77°F (25°C) = 128 - 163 min
• 500 gm pot life at 77°F (25°C) = 102 - 107 min
• Approximate working time at 77°F (25°C) = 7 - 8 hr
• Minimum shelf life is 2 years in unopened factory container (store at room temperature)

Note that to ensure proper mixing, which is crucial for expected performance, Pro-Set offers dyes for resin and hardener as a visual control of mixing thoroughness. A yellow dye (#551) in the resin and a blue dye (#552) in the hardener will yield a consistent shade of green when the proper ratio of resin/hardener is thoroughly mixed. Streaking due to insufficiently mixed resin and hardener is very apparent. See Related Products, below.
