Fluorinated additives for stain-resistant matt latex paints

Abstract

Latex paints are often preferred over solvent-based paints due to their good gloss and color retention, ease of handling, and lower volatile organic contents. However, matt latex paints tend to show poor stain resistance since they develop highly porous and rough surfaces. In recent years, matt latex paints have been improved in their stain resistance with resulting better cleanability, by adding hydrocarbon acrylic polymers and fluorine-containing compounds. In this work, we prepared fluorinated acrylic emulsions of the copolymer of butyl acrylate (BA) and perfluorobutylethylene (PFBE), which were introduced in latex paint compositions. The properties of the modified paints were evaluated by performing stain resistance tests with several domestic products. It was observed that they had good stain release properties, thus conferring good properties to the final painting system. They contain the self-cleaning behavior typical of fluorinated coatings, which have been proven by the decrease of their surface energies. Since the cleaning procedures of a matt paint film can also impart some gloss increase, the wet and dry burnishes were also evaluated. The results have shown improvements in stain resistance and cleanability of the modified matt latex paints with the maintenance of their stability and the coatings gloss as required.

Modification of a fluorine–silicone acrylic resin with a free‐radical‐catching agent

“…Organic fluorine and silicone have unique surface properties and features, including a low surface energy, high resistance to temperature, chemicals, and weathering, because of their low polarizability and high‐energy bonds, CF and SiO. They are well accepted for the modification of acrylic resins for fouling resistance, water repellence, and light durability .…”

Effect of Grafting Conditions on NR-s-g-HFMA Copolymer and its Thermal Stability

“…Nowadays, fluorinated polymer has attracted great attention from material scientists and becomes one of the most promising candidates in the fields of historic preservation [5][6][7], anti-fouling and self-cleaning coatings [8,9], biosensors [10,11], functional films [12,13] and devices for solar energy [14,15] owing to its outstanding liquid repellence, optical properties, high thermal [16], chemical and weather resistance [17], low coefficient of friction and good biocompatibility [18]. If NR-s molecular chain was incorporated fluorinated side chain, the potential good properties of fluorinated polymers may appear in NR-s. To our best knowledge, there are no report about modification of NR-s by fluorinated group, we study the Grafting conditions of fluorinated acrylate on NR-s and the thermal stability of the grafted NR-s.…”

Preparation of Fluorocarbon Acrylic Emulsion with Core-Shell Structure Modified by Versatate Carbon

“…The water-borne fluorocarbon coatings attract more research attention because of its unique surface properties and environment friendly. The films of the coatings not only keep the original properties of polyacrylate, but also have their unique properties due to the low polarizability and the strong electro-negativity of the fluorine atom, such as high thermal stability, chemical inertness and excellent water resistance [1][2][3][4]. Conversely, this chemical inertness presents challenges to the paint formulator, in that it prevents adhesion to substrates and makes it difficult to disperse pigments, and then limits its commercial applications.…”
