Fire Retardant Isophthalic Polyester AOC’s Vipel® K733-A series is a fire retardant isophthalic polyester resin that meets ASTM E 84 Class I with no synergists added. Vipel® K733-B is a fire retardant isophthalic polyester resin that meets ASTM E 84 Class I with 1.5% antimony trioxide added. Vipel® K733 series resins are ideally suited for use in hand lay-up, spray-up and filament winding processes where outstanding mechanical properties and mild chemical resistance are required. Benefits Fire Retardant The Vipel® K733-A requires no antimony trioxide spread to meet ASTM E 84 Class I flame spread requirements.Vipel® K733-B requires only 1.5% antimony trioxide to meet ASTM E 84 Class I flame spread requirements. Versatile Wide formulating capabilities allow for use in many processes and for optimization of cost/performance. Corrosion Resistance Vipel® K733 provides mild chemical resistance to a number of chemical environments.
