UV-5029 Balancing Resin


UV 5029 is a heavy, one component UV curable resin system having a specific gravity of 2.05.  It’s deep cure capability of over 1/8” in seconds, eliminates the need for long oven or room temperature curing of traditional epoxy systems.  UV 5029 may be fully cured while the part is in place on the balancing machine, making it immediately ready for the next manufacturing step or shipment to the customer.  It’s excellent adhesion, toughness and weight makes it an ideal candidate for many part balancing operations.
