Alkyd resin merupakan produk polimer yang banyak digunakan dalam industri cat, coating, dan pembuatan film. Hal ini dikarenakan keunggulan sifat – sifatnya sebagai surface coating meliputi fleksibilitas, kekuatan durabilitas, serta adhesi baik. Penelitian membuat alkyd berbasis palm fatty acid distillate (PFAD) urea formaldehide terbutilasi dengan variasi rasio molar butanol 0,5-3 mgrek/mgrek. ...

Cardanol, a waste from the food industry and widely produced (1 Mt/y), has been used as chain stopper during polycondensation of short oil alkyd resins in order to replace benzoic acid. Then, phosphorylated cardanol added both reduce solvent content bring flame-retardant (FR) properties resins. The renewable carbon formulations increased up 23%. impact introduction molecules on drying time flex...

In this study, Fourier transform infrared spectroscopy (FTIR) and luminescence imaging were used to identify the coatings of seven Persian lacquer papier mache penboxes, which two contemporary, one was from Pahlavi era, four belonged Qajar era. First, FTIR nature coating. Then, UV-induced visible at spectral ranges 420–680 nm (UVL), 425–495 (UVIBL), 615–645 (UVIRL) performed for further examina...
