| Vipel K733-A series is a fire retardant isophthalic polyester resin that meets ASTM E 84 Class I with no synergists 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 Vipel K733-A requires no antimony trioxide spread 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. Refer to AOC’s “Corrosion Resistant Resin Guide” for corrosion resistance information or for questions regarding suitability of a resin to any particular chemical environment contact AOC.&& |
