Get the Job Done Right the First Time and Every Time
3M™ Hi-Tack Composite Spray Adhesive 71 delivers a consistent fine mist spray with a high adhesive solids content for exceptional coverage. It is ideal for use in a wide variety of composite production applications, including the dry lay up and infusion process. The high tack formula allows faster lay up of fiber sheets and also faster bonding of layered composite assemblies. The formula has been optimized to have little or no intrusion in the infusion process to reduce the risk of delamination. This adhesive is available in clear, or in green for better visual control during application, and meets CARB and OTC VOC requirements.

- Lay up of fiber sheets
- Dry lay up and infusion process
- Bonding layered composite assemblies
- Closed mold infusion (RTM)
