50ml NovaWeld SignFix 7 (Box Of 12 Tubes)
Product Description
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
- Consult the SignFix material safety data sheet (MSDS) before using for the first time.
- Carry out surface preparation where required.
- 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.
- 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.
- Remove any excess adhesive at this point, before the structural glue starts to cure. Use a suitable cleaner such as NovaBond Surface Cleaner.
- 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.
