System Three SB-112 Surf Board Resin

System Three Surf Board Resin SB-112 epoxy is a clear, almost water-white, high-modulus epoxy resin system, specially formulated for use in building surf and sail boards over polystyrene cores. Unlike many epoxy resin systems it cures to a glossy blush free surface. It is unique in that polyester resins and gel coats may be bonded directly to it without using tie coats.

    Great Product and Great Service!


    I use this product on hollow wooden surfboards. I don't use anything else because this is the best. I really like the UV protection since it doesn't require a coat of varnish.




    System Three SB-112 Resin


    Of course System Three SB-112 is a great product and in my case it is the only epoxy resin that is compatible with polyester resin when polyester is to be used over an epoxy repaired area.The real story here though is Jamestown Dist.I have been a Jamestown customer for decades and I have never been disappointed with any product I purchased from them.
