Modification of latex polymers is an ongoing process to improve paint performance and it can be accomplished by various methods. In this study, styrene and n-butyl acrylate latex polymers are modified by three functional monomers (methacrylamidoethyl ethylene urea (MAEEU), dimethylaminoethyl methacrylate (DMAEMA), and glycidyl methacrylate (GMA)) alone or combined in different amounts in latex polymer formulations. Impacts of these functional monomers both on latex polymers, and paints made from these latex polymers are investigated. The characterization of the latex polymers are analyzed by differential scanning calorimetry (DSC), minimum film forming temperature (MFFT), dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). Scrub resistance, whiteness, hiding power, glossiness, hardness, contact angle, adhesion on annealed glass and hot-dip galvanized steel surfaces, and color retention properties of the paints are examined. The results are compared with a nonfunctional reference and a commercial styrene-acrylic-based latex polymer, separately. The outcomes confirm that alone and the combinations of these monomers in styrene-acrylic-based latex polymers improve the paint by enhancing scrub resistance, better adhesion on surfaces and the ability to control hydrophobicity and color efficiency.</p><h3>Graphical abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":48804,"journal":{"name":"Journal of Coatings Technology and Research","volume":"19 5","pages":"1421 - 1435"},"PeriodicalIF":2.3,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4697676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although two-component NIPU coatings based on the reaction of cyclic carbonates and aliphatic amines have emerged as a promising option, they are still associated with two significant drawbacks: lower crosslinking densities due to reduced functionality of the oligomers and low ambient-temperature reactivity. This study reports the utilization of a hybrid approach to address these drawbacks. Amine-functional NIPU oligomers (NI-PUPA) were synthesized by the reaction of cycloaliphatic amine functional compounds and multi-functional cyclic carbonates in an excess amine molar ratio. After mixing the NI-PUPAs with (3-glycidyloxypropyl) trimethoxysilane (GPTMS), a dual-curable coating could be achieved by ambient curing of amines and epoxies and moisture curing of alkoxy silanes. A comparative experimental design was implemented to evaluate the effect of an additional curing mechanism. The results revealed that the additional moisture curing led to faster ambient curing, faster development of properties, enhanced flexibility even at higher crosslinking densities, and better corrosion resistance. Such advancement could facilitate the future implementation of NIPUs in high-performance ambient-curing coating applications.</p></div>","PeriodicalId":48804,"journal":{"name":"Journal of Coatings Technology and Research","volume":"19 5","pages":"1393 - 1407"},"PeriodicalIF":2.3,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11998-022-00614-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4993290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three types of blended aqueous solutions (BN-CDs/WPU) with BN-CDs and water-based polyurethane were sprayed on the surface of cotton fabric, and then the cotton fabric was rolled and dried. The structure and optical properties of BN-CDs were characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet-visible spectrophotometry, and fluorescence spectrophotometry. The structure and ultraviolet screening capability of cotton fabrics after finishing with BN-CD/WPU blend solution were characterized. Results showed that the prepared BN-CDs were graphite-like nanocrystals with an approximately 0.3-nm crystal plane spacing. All BN-CDs had rich hydroxyl groups and amine groups on the surface, which made the BN-CDs soluble in water. BN-CDs had a strong absorption peak in the ultraviolet region and emitted bright blue fluorescence independent of excitation wavelengths. Cotton fabrics finished with BN-CDs/WPU all showed a high ultraviolet protection factor (UPF), an excellent level of protection, and good washing durability. In particular, in cotton fabrics treated with BN-CDs prepared using citric acid as a carbon source, the UPF value was still as high as 50.1 even after washing 10 times, and the fabrics maintained good elasticity and morphological characteristics.
