Phosphorus-containing reactants for UV-cured wood coatings.

Researchers have recently developed a phosphorus-containing reactive agent for ultraviolet curing, flame retardant wood coatings.
attempts to develop UV-RA, a phosphorous-based flame retardant for coating applications, have led to the synthesis of reactive compounds that can be used as UV crosslinkers and UV-cured epoxy acrylates low-polypolymers to form coatings. UV-RA is expressed through FTIR, NMR, hydroxyl and iodine

. By examining the thermal, mechanical and flame retardant properties, a study based on the effects of different amounts of UV-RA incorporated into the formula was studied.
flame retardant properties when coated with UV-RA
with increased UV-RA concentrations, all performance enhancements were observed, and each coating containing UV-RA successfully depicted flame retardant properties. The maximum burn loss (LOI) value obtained is 27, while the initial and final degradation temperature increases with the coke yield. With the exception of a low value of 20UV-RA, there is little change in mechanical properties.
the study was published in the Journal of Coating Technology and Research, September 2019, volume 16, Issue 5, pp. 1493-1502.
