A solventless adhesive coating composition and a threaded fastener product utilising such coating. The coating consists of 13 to 60% by weight of resin oligomer having a molecular weight from about 1000 to about 8000, about 40 to 80% by weight of monomer diluent, having a molecular weight from 75 to 700, ½ % to 15% by weight of a photoiniator agent to enable the coating to be initially cured onto the fastener and 0 to about 25% by weight of a tackifier agent. The adhesive coating on the fastener is a non-tacky partially UV cured solventless adhesive.
一种无溶剂粘合剂涂层组合物和使用这种涂层的螺纹紧固件产品。涂层由 13% 至 60% (按重量计)的
树脂低聚物(分子量在 1000 至 8000 之间)、40% 至 80% (按重量计)的单体稀释剂(分子量在 75 至 700 之间)、 ½% 至 15% (按重量计)的光敏剂(使涂层能够在紧固件上初步固化)和 0% 至 25% (按重量计)的增粘剂组成。紧固件上的粘合涂层是一种非粘性的部分紫外线固化无溶剂粘合剂。
