Polyester Resin Unwaxed 1 Gallon

Unwaxed general purpose laminating resin for wet layup. Low viscosity wets fabric well with minimal drain on vertical surfaces. Unwaxed resin is air-inhibited and will stay tacky on the surface when cured, allowing for extra laminating or bonding without further prep or sanding. It is designed for use in the manufacturing of composite parts using hand lay-up or spray-up application methods. For those marine applications where improved resistance to blistering is required, a skincoat of H034-A is recommended, H100-W or H100-M be applied on the hull prior to the application of H596-H. The medium reactivity of H596-H resin allows for complete rapid cure of the composite even in relatively thin composites when used with the recommended peroxide levels and application temperature. Both the non-air inhibited and the air inhibited versions of H596-H resin provide good chemical bonding between laminate application if proper application procedures are followed. The air inhibited versions provide the best secondary bonding and should be used in applications where maximum secondary bonding is required. When used with the proper glass reinforcement content, it produces a composite with superior toughness properties that can assist in the reduction of composite cracking. Working time @ 25 C = 20-25 min.
