The unique Bond® LITE & DRY® formula, pure white in color, is "thermoset" into the cloth under the industry's hightest temperatures and pressures, so that it resists transfer to glass or polished surfaces, on slightly warm surfaces and in other critical applications. It was originally developed for use in the sensitive electronics fabrication "lay-up" process that produces CCL's (copper-clad laminates) for circuit boards. The cloth is a medium weave of 20/16 mesh (USP VI - 32 yarns/inch) cotton gauze. Bond uses only US Pharmacopoea (USP) medical-grade gauze. Flat-stacked 100 pieces in a poly bag. Cut Bulk pieces are 36 inches folded to 4-ply, 9 inch width by 18 inch cut length. Cut Bulk is an economical alternative to individually bagged pieces.
