ABSTRACT

Although BEVA 371 film is almost synonymous with leather and skin repairs because of its flexibility and ease of use, Lascaux adhesives 498HV, 303HV (formerly 360HV), and 498 20-X have also been used for years on these types of object treatments with successful results. Not only do they adhere well to leather and skin, but also to entomological specimens and other related organics. Lascaux adhesives are easy to handle, remain flexible when set, and adapt to different situations. This article explains multiple application methods: direct wet-application, as a heat-activated and solvent-activated coated lining, pressure-sensitive tape, and as a bulked adhesive shapeable fill material. Because original substrates are often thin or associated with areas of loss, suitable lining materials and bulking agents are also reviewed. Three case studies – a vegetable tanned leather doctor's bag, pinned butterflies, and a taxidermy golden eagle – demonstrate how the materials can be used in multiple treatment steps.

摘要

尽管 BEVA 371 薄膜因其灵活性和易用性而几乎成为皮革和皮肤修复的代名词，但拉斯科粘合剂 498HV、303HV（以前称为 360HV）和 498 20-X 也已在这些类型的物体处理中使用多年，并取得了成功结果。它们不仅能很好地粘附在皮革和皮肤上，而且还能粘附在昆虫标本和其他相关有机物上。拉斯科胶粘剂易于处理，凝固后保持柔韧性，并能适应不同的情况。本文介绍了多种应用方法：直接湿式应用、作为热活化和溶剂活化涂层衬里、压敏胶带以及作为散装粘合剂可成型填充材料。由于原始基材通常很薄或与损失区域相关，因此还审查了合适的衬里材料和填充剂。
