Aeroflex ADHBLK Armaflex Insulation Adhesive with Brush

Product Description

The AEROFLEX ADHBLK is a contact-style adhesive formulated for use with Armaflex closed-cell elastomeric insulation. Supplied in a 0.5-pint container with an integrated brush applicator, it bonds Armaflex sheet, tube, and roll insulation to itself and to metal, plastic, and other common mechanical-system substrates. HVAC and plumbing technicians use it when sealing seams, joints, and butt ends on pipe insulation systems where a tight, void-free bond is required to maintain thermal performance and prevent moisture ingress.

This adhesive is suited for residential and light commercial mechanical insulation applications. Typical use cases include sealing longitudinal seams on pre-slit pipe insulation, bonding sheet insulation to duct surfaces, and patching or repairing existing Armaflex installations. The brush-in-cap design allows for direct, controlled application without a separate applicator tool, making it practical for field service and retrofit work.

Key Features

• Contact adhesive formulated specifically for closed-cell elastomeric foam insulation
• Integrated brush applicator included — no separate tool required
• 0.5-pint container sized for targeted field repairs and smaller installations
• Bonds Armaflex to itself as well as to metal and plastic substrates
• Supports vapor-seal integrity at insulation seams and joints

Compatibility

Designed for use with Armaflex closed-cell elastomeric insulation products including pipe insulation tubes, sheets, and rolls commonly used in HVAC and plumbing piping insulation systems.

Installation Notes

Mechanical insulation work of this type is typically performed by HVAC technicians or plumbing contractors. Before applying adhesive, ensure all pipe surfaces are clean, dry, and free of oil or debris. Apply adhesive to both mating surfaces, allow adequate open time per the manufacturer guidance before pressing surfaces together, and work in a well-ventilated area as solvent-based contact adhesives produce vapors during application and cure. Follow all applicable local safety and mechanical codes governing insulation installation.
