Ecofriendly adhesion promoter for UV curable coatings
用于UV固化涂料的环保型附着力促进剂
Researchers have studied a novel high performance, low cost, and environmentally friendly adhesion promoter – which can also can significantly enhance the corrosion protection properties of the coating.
研究人员研究了一种新型的高性能、低成本、环保的附着力促进剂,它还可以显著提高涂层的防腐性能.
The study offers a new strategy to tackle adhesive failure in UV-curable coatings.
Aiming at enhancing the adhesion of UV-curable coatings to metal surfaces, a phytic acid based adhesion promoter with photo-curable group (PA-GMA) was designed and prepared via a ring opening reaction of phytic acid (PA) and glycidyl methacrylate (GMA) in aqueous solution.
该研究为解决uv固化涂料的附着失败问题提供了一种新的策略.
为了提高紫外光固化涂料对金属表面的附着性能,采用植酸(PA)与甲基丙烯酸甘油酯(GMA)在水溶液中开环反应(ring opening)制备了植酸基光固化基附着力促进剂(PA-GMA).
Outstanding corrosion protection properties
优异的防腐性能
The developed PA-GMA could significantly improve the adhesion strength between UV-cured coatings and metal substrates, which was superior to that of commercial phosphate ester adhesion promoters. Accompanied by the significantly enhanced adhesion performance, outstanding corrosion protection properties were also demonstrated. As the scientists point out, their study offers a novel route to prepare an ecofriendly and low-cost adhesion promoter using natural compound and a new strategy to tackle adhesive failure in UV-curable coatings.
所研制的PA-GMA能显著提高uv固化涂料与金属基底的附着力强度,其性能优于市售磷酸酯类附着力促进剂.在显著增强附着性能的同时,还具有优异的防腐性能.
正如科学家指出的那样,他们的研究提供了一种利用天然化合物制备生态友好和低成本附着力促进剂的新途径,以及一种解决紫外线固化涂料附着失败的新策略.
