PPG Industries has expanded its line of SEMCO™ sealant removal tools with ergonomically designed scrapers that can reportedly improve efficiency of aerospace sealant removal and reduce operator fatigue. According to Dillon Desai, global market development manager for packaging, 10 scrapers have been designed for use by hand for standard sealant removal, as well as more difficult and specialty applications such as the removal of sealant around fasteners, fillet seals, and other hard-to-reach areas.

Five tools are made of glass-filled nylon materials for more difficult operations, while an additional five tools designed for standard sealant removal by hand are made of CELCON® acetal copolymer (POM). The tools have a variety of widths, from 1/4 to 3 ½ in., with eight scrapers having straight ends, one having an angled end, and one with a pointed-tip design. The tools can reportedly be sharpened for continued use.
