Coatings, comprising a resin and a hardener, wherein the resin is obtained by reacting nano-particle sol(s) of organofunctional silanol(s) exhibiting reactivity towards amino, amide, nitrile or/and isocyanate groups, with alkyl siloxane(s) and optionally organic binding agents, both exhibiting reactivity towards amino, amide, nitrile or/and isocyanate groups; and wherein the hardener comprises a component A comprising siloxane(s) having amino, amido, isocyanate and/or nitrilo groups; and/or comprising polyisocyanate; as well as a component B comprising one or more of an α,ω-aminofunctional, α,ω-amido-functional, α,ω-isocyanate-functional and α,ω-nitrilo-functional polysiloxane, is provided. The coatings may either be obtained as a one component or as a two component coating which are useful as permanent anti-graffiti coatings.
由树脂和固化剂组成的涂料,其中树脂是由对氨基、酰胺、腈基或/和异氰酸酯基具有反应活性的有机官能团硅烷醇的纳米颗粒溶胶与烷基硅氧烷和可选的有机结合剂(两者均对氨基、酰胺、腈基或/和异氰酸酯基具有反应活性)反应而得;其中固化剂包括由具有氨基、酰胺基、异氰酸酯基和/或硝基的硅氧烷组成的 A 组分;和/或由多异氰酸酯组成的 A 组分;以及由具有α,ω-氨基官能团、α,ω-酰胺官能团、α,ω-异氰酸酯官能团和α,ω-硝基官能团的聚硅氧烷中的一种或多种组成的 B 组分。这种涂料既可以是单组分涂料,也可以是双组分涂料,可用作永久性防涂鸦涂料。
