The main difference is viscosity, but both are used in the 2:1 Non-Blushing Epoxy System. This system consists of 2 resins, LV and FLAG, and 3 non-blushing hardeners, Slow, Medium and Fast, with a simple 2 parts resin to 1 part hardener (2:1) mix ratio by volume. Both resins result in a non-blushing, low odor epoxy laminating system that can be used for a wide range of applications such as laminating, clear coating, gluing, and filleting. The two resins are very similar, with the main difference being that LV Resin is lower in viscosity, or thinner, than FLAG Resin. This resulting difference in handling properties of the mixed resin and hardener makes each resin more user friendly and ideally suited for certain applications.
LV Resin should be primarily used laminating reinforcement fabrics like fiberglass cloth as the resulting low mixed viscosity allows the user to easily and quickly wet-out reinforcement fibers, mats, fabrics and so on. FLAG Resin works best for clear coating, bonding and filling. The resulting medium mixed viscosity is ideally suited for clear coating, holds a thicker bond line, has improved sag resistance on a inclined surface to resist running and readily accepts fillers to make filleting/fairing compounds. Fillers like Colloidal Silica, Cell-O-Fill, Wood Flour, and Phenolic Micro Balloons can be added to either mixed resin and hardener to make compounds for bonding, filleting, fairing or filling.
Laminating: LV Resin
Clear coating, Bonding, Filleting, Fairing, Filling: FLAG Resin
