At elevated temperatures, they can be cured in as little as two seconds. the cheaper grades are sometimes lower in weight cost than the general purpose. UREA-FORMALDEHYDE RESIN, ISOBUTYLATED. Good electrical insulation properties with particularly good resistance of tracking. Infact, they are some of the fastest curing resins available. The optimum temperature for microbe activity is around 70–90 °F (21–32 °C).[5]. If this ratio is reduced in the course of the formation reaction, the resulting resin will possess highly adhesive properties. Global Urea Formaldehyde Resin Market Growth 2020-2025.
