Researchers found that the introduction of thiocarbamate and thioether bonds into the polymer backbone using thiol-click chemistry accelerates the formation of a novel waterborne coating that exhibits high hardness, strength and fast curing.

The relevance of anti-corrosion coatings for aluminium continues to grow, especially with the increasing use of aluminium alloys in various industries such as automotive, aerospace and construction. Source: Adobe.Stock

The research proves that the optimised composition of the WPTUA dispersion system, especially with a content of 16 wt% TMPMP and 28 wt% PETTA, results in films that exhibit high hardness, excellent water resistance and good thermal stability on sensitive substrates such as paper, plastic and wood.

The mechanical and anti-corrosive evaluation of a hybrid epoxy resin–SiO2 and graphene oxide (GO) are presented. Three composite materials were prepared with 0%, 0.1 wt% and 0.5 wt% GO concentrations. The hybrid material was prepared by the sol-gel process incorporating the silica particles in situ within the epoxy resin (ER) matrix and previously that ER was functionalized with carboxyl groups using abietic acid and labeled as functionalized epoxy resin. The deposition of the three hybrids in aluminum 6061 substrates was made by blade coating, measuring wet and dry film thickness. The study of mechanical properties involved adhesion, pencil scratch hardness, and abrasion test methods where the incorporation of 0.5 wt% of GO improved the mechanical properties considerably.
