ARALDITE® 2053: The methacrylate adhesive for reliable, durable industrial joints

To ensure optimum bonding, it is crucial to meticulously treat the surface of the materials to be assembled before any application.

With this in mind, Samaro and its partner Socomore recommend the use of Diestone DLS. It is a fast-evaporating, chlorinated hydrocarbon-free solvent-based cleaner, degreaser, providing excellent surface preparation for effective bonding.
