Plexus Intros 3 New Structural Adhesives
Structural adhesives. ?
Danvers, MA — Three new Plexus
structural adhesives reportedly provide exceptionally strong yet flexible bonds on composites and offer medium-to-long working times for large assemblies. The adhesives require little or no surface preparation and will cure at room temperature to tough, durable bonds that withstand service temperatures of -40 to +180°F (-40 to +82C).
The adhesives, two-part structural methacrylates can be dispensed manually or with standard meter-mix equipment. They are designated MA530, MA560-1, and MA590, and are 100 percent non-sagging gels recommended for joining composite assemblies, ABS, acrylics, FRP, gelcoats, polyesters, PVC, styrenics and vinyl esters. They can be used for boats, trucks, buses, architectural ornamentation, wind turbine blades and composite bridges and decks.
MA530 has a working time of 30 to 40 minutes and fills gaps up to 0.70-in. A 0.03-in. bond line reaches approximately 75 percent of its ultimate shear strength in 90 to 160 minutes at 74°F (23°C). It is available in ready-to-use 400ml cartridges, 5-gallon pails and 50-gallon drums.
MA560-1 has a longer working time of 55 to 70 minutes and fills gaps up to 1.00-in.It is recommended for large structures as well as small-part assembly where fewer workers are required. Fix time for a 0.03-in. bond line in 220 to 240 minutes at 74°F (23°C). It is available in ready-to-use 400ml cartridges, 5-gallon pails and 50-gallon drums.
MA590 has a working time of 90 to 105 minutes and was formulated for building large fiberglass boats, and is also appropriate for other applications. It fills gaps up to 1.00-in. and is recommended for certain metals in addition to many other substances. A 0.03-in. bond line reaches approximately 75 percent of its ultimate shear strength in 180 to 240 minutes at 74°F (23°C). It is available in ready-to-use 400ml cartridges, 5-gallon pails and 50-gallon drums.
