Strengths
What it’s good at
Water-thin capillary solvent welding for cast and extruded acrylic (Plexiglas, Lucite) display cases, boxes, and signage — draws rapidly into tight hairline seams to create optically clear, high-strength chemical bonds.
Limits
Where it falls short
Requires precise flat mating surfaces (zero gap-filling ability); not for cross-linked acrylic, wood, metals, or dissimilar non-solvent plastics.
