AllWeld 525 – Clear Plastic Adhesive Gel

Code: MMA525


Clear Acrylic & Plastic Bonding Gel for non-drip, vertical applications etc.


Sylmasta AllWeld 525 is a two-part, high strength, clear structural adhesive gel for bonding plastics and composites. AllWeld 525 is thixotropic, meaning that it doesn’t run and can be applied to vertical surfaces with minimal dripping or sagging.


AllWeld 525 uses the latest in toughened methacrylate technology to produce an adhesive with high shock resistance and high tensile strength, and with excellent UV and chemical resistance. It is supplied in a 50ml cartridge with mixer nozzle for ease of application.


AllWeld 525 produces a high strength, load-bearing bond to acrylic, polycarbonate, engineered plastics, exotic metals and other difficult substrates. It produces tough, adhesive bonds with little or no surface preparation or priming and cures rapidly at room temperature to provide exceptional shear and peel strengths and excellent environmental resistance.


  • High strength bonds to load bearing metals, plastic, wood, composites etc.
  • Bonding acrylic and Perspex in the manufacture of point-of-sale dispays
