Rapidstick™ 8-420 Structural Adhesive

Rapidstick™ 8-420 Methacrylate Structural Adhesive is a versatile and convenient 10:1 dual component, 100% reactive, low shrinkage, high elongation formula, used for bonding an expansive array of metals, thermoplastics, thermosets, and composite assemblies, without the need for surface primers or conditioners.

8-420 offers an extremely strong, flexible bond, with excellent peel and sheer resistance, high fatigue endurance, and high impact strength – at both low and elevated temperatures. Its non-sagging and thixotropic formulation ensures that bonding can be undertaken quickly and from multiple angles within a working time of 3 to 4 minutes, achieving 80% ultimate strength in as little as 18 minutes.

This innovative new generation high grade blend of low-odour, non-flammable, and non-carcinogenic monomers further extends the progression into our Responsible Chemistry program.

8-420 is commonly used for:

• Bonding locators to ACM without read-though or witness marks
• Bonding mild steel frames to FRP, assuring high vibration and impact resistance
• Bonding fasteners to GRP and FRP moulded parts
• Bonding and laminating composite panels
• Composite and metal fabrication for seating construction
