Is there a clear structural adhesive?

Eb 1353


Most structural adhesives, whether they are epoxies, urethanes, acrylates etc, most are either pigmented or filled. This leaves a lack of options when needing optical clarity. EB-135 is an unfilled, optically clear, low viscosity epoxy adhesive. Unlike many other clear, unfilled epoxy systems, EB-135 is a convenient 2:1 mix ratio allowing it to be used via dual cartridges. Using dual cartridge systems eliminates the need for mixing and weighing which can be a large burden on operators.
