Novel multifunctional unsaturated polyester polyols, UV-curable top coat formulations including these polyols, and a one-step process for preparing these polyols, are disclosed. Surface coverings and surface covering components including these top coat formulations are also disclosed. The polyols are generally formed by the ring opening polymerization of a lactone with a compound of the formula (R1)aR(OH)b, where a + b > 2. R1 is a double bond-containing moiety such as allyl, vinyl, vinylidene, vinyl ether, acrylate, and the like. R is generally an alkyl, aryl, aralkyl, alkaryl, ether or ester group, including substituted versions thereof. R can be a polymer, including polymers with a plurality of functional groups. Examples of lactone groups which can be used include caprolactone, lactide and glycolide. The polyols can be used in 100% solids, solvent and water based radiation cured coatings, thermal cured coatings, dual cure (thermal with UV/e-beam, or UV/e-beam with thermal curing) coatings, and other types of coatings. These new resins enhance coating performance due to their multi-functional groups in the polymer chain.
本发明公开了新型多功能不饱和聚酯多元醇、包括这些多元醇的紫外线固化面漆配方以及制备这些多元醇的一步法工艺。还公开了包括这些面漆配方的表面覆盖物和表面覆盖物成分。多元醇一般由内酯与式 (R1)aR(OH)b 的化合物开环聚合而成,其中 a + b > 2。R1 是含双键的分子,如烯丙基、乙烯基、亚乙烯基、乙烯基醚、丙烯酸酯等。R 通常是烷基、芳基、芳烷基、烷芳基、醚基或酯基,包括其取代型。R 可以是聚合物,包括具有多个官能团的聚合物。可使用的内酯基团包括己内酯、内酯和乙二醇内酯。多元醇可用于 100% 固含量、溶剂型和水基辐射固化涂料、热固化涂料、双固化(热固化与紫外线/电子束,或紫外线/电子束与热固化)涂料以及其他类型的涂料。由于聚合物链中含有多功能基团,这些新型树脂可提高涂料性能。
