  • Nowadays, various polymeric materials are commercially available and used in many applications such as protective coatings, civil engineering materials, aerospace composites, automotive fields, and marine industries
  • The amine hydrogen molar mass of Epikure F205, which was employed as a curing agent, was reported to be 105 g/eq each amine hydrogen reacts with one epoxy group and the was reported to be 105 g/eq each amine hydrogen reacts with one epoxy group and the stoichiometric ratio of the curing agent to epoxy resin for curing reaction can be determined stoichiometric ratio of the curing agent to epoxy resin for curing reaction can be determined according according to AHMM/epoxy molar mass = 0.56
  • Because Tinuvin 1130 does not have any absorption like epoxy
  • Tinuvin as an organic absorber played a major role investigation, it was determined that Tinuvin 1130 as an organic ultra violet absorber played a major in role against
  • It is proposed that Tinuvin the chemical properties butbut cancan prevent or or at at least reduce thethe drop in in thethe cannot notonly onlypreserve preserve the chemical properties prevent least reduce drop mechanical properties
  • Other studies was reduced roughly by 25%
  • Increasing Tg reduced the mobility of the polymeric chains, demonstrating the significant contribution of Tinuvin 1130 to the protection of epoxy coating against UV light
  • ultra violet damage damage could could not not progress progress well presence well and and it it remained remained at at the the early early stages. stages
