IMPCO has introduced Polyflex FR fire-resistant resin for sealing electronic connectors, wires, and wiring assemblies against corrosion. The company claims that the product has water-wash capability and that their impregnation process creates a permanent flame-retardant barrier that can also prevent corrosion associated failures by filling gaps and pores in electronic connectors and wiring. The company states that the product is cured at temperatures below the threshold of sensitive components, and that the cured resin will not liquefy, melt, or burn. The company also states that the product does not require any special ventilation or handling during use, and has an indefinite pot life when properly stored. A UV-activated colorant allows identification of impregnated components, and the product has a claimed high flexibility and heat resistance and can be used in applications with frequent thermo-cycling and high vibration.
