SB-112 is a clear, almost water white high-modulus epoxy system,
UV-resistant for maintaining longer surface gloss. Unlike many epoxy systems, SB-112 will cure to a clear, glossy, blush-free surface.

Recommended Uses:
SB-112 is specially formulated for use in building and repairing sail and surfboards over polystyrene cores. It can also be used for coating and composite laminating.
SB-112 is unique in that polyester resins and gel coats may be bonded to it without the use of “tie-coats”. We recommend that polyester be bonded onto freshly sanded SB-112 epoxy within 48 hours of cure.
