Permabond TA4207 expands our existing range of methyl methacrylate (MMA) adhesives, and is a 2-part, 1:1 mix ratio product that achieves very high shear strengths on a wide range of metals, plastics, and composites, with little or no surface preparation. In fact, in laboratory tests, our chemists have even achieved substrate failure on difficult materials like PET-G, with minimal acetone/IPA degrease. Furthermore, this multi purpose adhesive performs outstandingly well on metals, cutting through oxide layers to form incredibly strong bonds with the parent material. But the high shear strength achieved on unprepared oily steel is even more impressive!
TA4207 is available in 50ml and 400ml cartridges. It is also available in bulk on request, for high speed production lines.
1) Surfaces must be clean, dry, and grease–free. If using a cleaning solvent, allow 3–4 minutes to fully evaporate before applying adhesive.
2) Then, apply a thin bead of adhesive pre–mixed through a static mixer nozzle.
3) Or alternatively, apply a thin layer of resin on one component and hardener on the other.
4) Assemble components and clamp.
5) Maintain pressure until handling strength is achieved. The time required will vary according to the joint
design and surfaces being bonded.
6) Finally, allow 24 hours for the adhesive to fully cure. Accelerate cure times by heating.
