Carbon-neutral policy and technological race on the powder coatings market force to develop more advanced, safer, cheaper, naturally sourced products. To meet needs, coating compositions were prepared from safe natural-origin hardeners, resins, fillers rosin, bio-diols, bio-epichlorohydrin, halloysite, investigate their thermal, mechanical, functional properties in comparison with petroleum-bas...

Epoxy is extensively used for anti-corrosion coatings on metallic materials. Conventional epoxy have a permanent crosslink network that unable to repair itself when cracks and damages occur the coating layer. This study aims develop self-healing vitrimer/carbon nanotube (CNTs) nanocomposite coating. Two bio-based curing agents viz., cashew nut shell liquid (CNSL) citric acid (CA) were employed ...

Epoxy is a material of choice for demanding applications thanks to its high chemical stability, stiffness, and strength. Yet, brittle fracture behavior an important downside many sectors. Here, we show that the addition electrospun thermoplastic nanofibers viable toughening strategy design nanofiber reinforced epoxy materials with excellent toughness. Moreover, use transparent film-like specime...

We have developed novel antibiocorrosive multifunctional hybrid materials based on functionalizedperfluoroalkylmethacrylate copolymerswith epoxy groups in main chainsand selected biologically active compounds.The hybrids are transparent, showgood adhesion to various surfaces (plastic, wood),high viscoelastic recovery scratch testing,low wear rates and glass transitions above 323 K. No phase sep...

The moisture sensitivity of wood–polymer composites (WPCs) is mainly related to their hydrophilic wood components. Coatings are among the alternatives that improve dimensional stability these composites. However, adhesion most coatings WPC surface generally poor. Thus, chemical and/or mechanical treatments should be applied coating adhesion. Therefore, main objective this study was polypropylen...

Epoxy resins are thermosetting polymers with an extensive set of applications such as anticorrosive coatings, adhesives, matrices for fibre reinforced composites and elements electronic systems automotive, aerospace construction industries. ?he use epoxy in many high-performance is often restricted by their brittle flammable nature, the relatively low fracture toughness poor thermal electrical ...

In the present study, Mg-Al layered double hydroxide (Mg-Al/LDH) was synthesized on surface of AZ31 Mg alloy substrate via in-situ hydrothermal treatment. Synthesis parameters were changed to determine their effect lateral size LDH. For this purpose, etching in nitric acid and anodizing sodium solution performed as pretreatments. Moreover, influence LDH pH (10 11) coating investigated. Morpholo...

Powder coatings are a green alternative to conventional solvent-borne liquid coatings, but they have the intrinsic drawback of color-matching and adjustment in production with extrusion process. In this study, an industrially applicable approach formulate color powder utilizing ultrafine powders, i.e., powdery blending pressing method, was invented. This novel method validated by comparing samp...
