NovaWeld Flex HTFC & HT
NovaWeld Flex HTFC & HT are two-part structural methacrylate adhesives formulated for applications intended for the powder coating process. Sharing common chemistry, they differ only in the functional cure-speed, allowing diversity of applications. Both grades offer a high functional tensile shear strength after the initial cure, that further increases following an additional heat cure process (30 min@180ºC / 20…

NovaWeld Flex HTFC & HT are two-part structural methacrylate adhesives formulated for applications intended for the powder coating process. Sharing common chemistry, they differ only in the functional cure-speed, allowing diversity of applications.
Both grades offer a high functional tensile shear strength after the initial cure, that further increases following an additional heat cure process (30 min@180ºC / 20 min@200ºC). This unique chemistry allows these grades to not only maintain a high functional strength through the powder coating process, but actually improve in all aspects of functional strength performance.
Applications
NovaWeld Flex HTFC & HT are very versatile, and can bond a wide variety of substrates without the need for surface primers or conditioners. Typical examples shown below:
- Bonding mild steel straps on structural sheet work
- Sealing weld seams
- Bonding stainless and aluminum letters and signs
- Bonding mild steel
Instructions For Use
- Consult the material safety data sheet (MSDS) before using for the first time.
- Carry out surface preparation where required.
- Remove nut and 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 dependent on grade used and the environmental conditions) before moving or unclamping.
