Material Notes:
3M™ Scotch-Weld™ Epoxy Adhesive DP105 Clear is a fast setting, very flexible 1:1 mix ratio epoxy adhesive/sealant. Its flexibility when cured makes it ideal for applications involving dissimilar surfaces where thermal coefficient of expansion may be a problem. It is also unique in that it retains its clear, colorless properties even when cured in larger masses where many clear epoxy systems will often turn amber from the reaction exotherm.Information provided by 3M
