SOCOMORE SKYRESTORE 407-5 (5-Ltr)

Additional Product Information

Overview

SKYRESTORE 406 & 407 is a professional aerospace-grade cured sealant and adhesive remover designed for OEM manufacturing and MRO maintenance operations. The product is used to efficiently soften and remove fully cured polysulfide, polythioether, and RTV sealants from aircraft structural and mechanical components. Aviation maintenance teams rely on this solution for its rapid action chemistry, NMP-free formulation, and improved workplace safety profile compared to traditional sealant removal agents.
