In continuous to our previous work, we were synthesized flame retardant polyols using the bis(2-hydroxyethyl) terephthalate derived from chemical scavenging of post-consumed clothes. Phosphorous containing polyols and diisocynates were mixed in appropriate molar ratio in reference to prepare flame retardant PU coatings. Various mechanical, chemical and flame resistance properties of prepared PU coatings were investigated. The formulated PU coatings showed higher flame retardency over the PU coatings synthesized from petro-based raw materials. A mechanical and chemical property also shows as high as that of PU coatings from petro-based raw materials. In order to evaluate flame retardant properties of the PU coatings limiting oxygen index analysis and UL-94 test methods were performed. Utilizing recycled product as replacement to petro-based raw materials in PU coatings, hence waste management indeed.
