Description

A durable, versatile bond that builds structural integrity without leaving witness marks on the sign face.

NovaWeld SignFix 33 polyurethane glue – 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

Automotive: Improves the structural integrity of vehicle roofs, spoilers, vents and housings without ‘read-through’ (see below).

Why NovaWeld SignFix 33 Dibond adhesive?

The strongest bonds can carry the risk of ‘read through’, a surface marking that is the result of a chemical reaction between adhesive and surface. NovaWeld SignFix 33 delivers an uncompromisingly strong bond without read through – ideal when structural integrity and aesthetics are equally important.

When compared to traditional two-part polyurethane glues, NovaBond SignFix 33 also delivers:

  • Greater shear, peel and tensile strength for stronger performance under stress
  • Impact resistance
  • Long lasting bonds, indoors and out

How to apply NovaWeld SignFix 33 polyurethane 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 minutes depending on environmental conditions) before moving or unclamping. Full cure and ultimate bond strength will take 24 hours to achieve.
