Products - NovaWeld SignFix 12


NovaWeld SignFix 12 is a high strength two component structural acrylic adhesive, designed to bond a variety of substrates that require a totally clear, high viscosity adhesive.

This ultra-high strength is achieved by using a bespoke blend of advanced acrylic polymers which, when combined with a non-phthalate and non-MCL cure system, provide a fast bond speed with ultra-high clarity.

Protects against the elements, and protects the look of the finished product,a clear structural adhesive that delivers uncompromising bond strength without the visible bond lines.

NovaWeld SignFix 12 clear plastic glue – ideal for:

  • Signage: High impact, high strength bonding of most signmaking materials including metals, plastics and composites.
  • Especially suited to clear acrylics where you need a virtually invisible bond to enhance the visual appeal of your sign.

Why NovaWeld SignFix 12 clear plastic glue?

In almost every conceivable way, NovaWeld SignFix 12 takes the traditional two-part structural adhesive and improves on it with:

  • Greater shear, peel and tensile strength for stronger performance under stress
  • Impact resistance
  • Long lasting bonds
  • Clear formulation for a sharper finish

Please note: If you intend to bond different materials for exterior use (eg rimless letters) ensure you choose an adhesive that will compensate for differential expansion. Please call for advice.

How to apply NovaWeld SignFix 12 clear structural 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 3-5 minutes depending on environmental conditions) before moving or unclamping. Full cure and ultimate bond strength will take 24 hours to achieve.
