Plexus MA 300 1 oz manual dispensing kit is a two-part methacrylate adhesive designed for structural bonding of thermoplastic, metal and composite assemblies. It is Cream in color. Plexus 300 is one of the more commonly used adhesives for a number of reasons. It adheres to most substrates. MA 300 is a simple one-to-one mix ratio. With such a rapid cure time, it makes for quick repairs, yet has nearly three times the tensile strength of 5200. Many professional boatbuilders use this product and swear by it.

Comments about Plexus Plexus MA 300 All Purpose High Strength Adhesive:

I purchased this to fill in some gouges on the bottom of a Royalex material canoe. Working time was less than two minutes at 65 degree air temperature but it is simple to mix. The MA300 worked well in this applicaton. I did try it on a broken fiberglass hinge on a truck cab console cover and found that MA300 had insufficient strength after fully curing. Went to West System 5:1 epoxy with micro filler. Curing was much longer but a far better product for this requirement.

Comments about Plexus Plexus MA 300 All Purpose High Strength Adhesive:

Perfect for glued in sailboat windows (vintage C&C).
Only complaint was color - ad correctly says cream, but I called and a sales person noted the tubes were black colored and the tube labels said "BLACK" contents - I wanted black, I ordered it, it WAS cream....

Comments about Plexus Plexus MA 300 All Purpose High Strength Adhesive:

I recently moved across the country with my family. The moving company promised me that they would take good care of my old town canoe, but they didn't! I found a deep gouge on the bottom of the Hull. The gouge did not go all the way through so I bought some of this Plexus MA 300 adhesive,[...] We lightly sanded the area, taped up a small square and applied the Plexus. It dried very quickly! It doesn't look bad either. I can always paint over the area if I need to in the future, but for now I am happy that my boat is back in good health. Great product. [...]. If you have a small gouge, dent or other small repair for your royalex boat, try using this product.
