Products - NovaWeld SignFix 7


Durable, versatile and incredibly powerful, make NovaWeld SignFix 7 your adhesive of choice for bonding metals, composites and engineering plastics.

NovaWeld SignFix 7 methacrylate structural adhesive – ideal for:

Signage: Structural bonding, especially when you need high impact strengths. Bonds most sign making materials, including:

  • Mild and stainless steels
  • Aluminium
  • Polycarbonate and acrylic sheets
  • Composite panels
  • Stone and ceramics

Manufacturing: Use to bond bighead fasteners and other locators onto aluminium composites in the signage, construction, marine, utility, petrochemical industries, and in general manufacturing.

Automotive: Protects the integrity of vehicle roofs, spoilers, vents, housings.

Other: SignFix 7 is the structural adhesive solution for wind turbines, fibreglass and sports goods.

Why NovaWeld SignFix 7 structural glue?

NovaWeld SignFix 7’s anti-sag properties means the bond won’t run, even on vertical surfaces. The high temperature glue formulation lets you bond metal parts prior to powder-coating and oven stoving cycles.

You don’t need to prime surfaces to achieve a strong bond, and once in place the bond will be highly resistant to shearing, peeling, solvents, moisture, lubricants and cleaning chemicals – even when used to fill larger gaps.

How to apply NovaWeld SignFix 7 methacrylate adhesive

  1. Consult the SignFix material safety data sheet (MSDS) before using for the first time.
  2. Carry out surface preparation where required.
  3. Remove cap. Repeatedly press the gun trigger until both parts are dispensing before attaching mixer nozzle. This ensures you mix equal amounts of adhesive and activator.
  4. Apply the mixed adhesive to one surface. Assemble components carefully and clamp if required. Take care not to over-tighten – you need to leave some adhesive between the joint.
  5. Remove any excess adhesive at this point, before the structural glue starts to cure. Use a suitable cleaner such as NovaBond Surface Cleaner.
  6. Allow the adhesive sufficient time to achieve handling strength (working time is 5-10 minutes depending on environmental conditions) before moving or unclamping. Full cure and ultimate bond strength will take 24 hours to achieve.
