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
- 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 minutes depending on environmental conditions) before moving or unclamping. Full cure and ultimate bond strength will take 24 hours to achieve.
