The Epoxy Resin LY 556 is extensively used as a reinforcing material due to its medium viscosity and chemicals resistivity. Property of this resin can easily be modified within wide limits with the use of fillers and hardeners. The composition of this resin is based on Bisphenol-A which makes it suitable for high-performance FRP composite applications such as pultrusion, pressure molding, filament winding and so on. Our resin is known for exceptional mechanical, good fiber impregnation and thermal & dynamic properties. Also, the Epoxy Resin LY 556 is having a low tendency to crystallize, thats why it is preferred for aircraft and aerospace adhesives.
