Description

All Durodyne air duct installations for heating, cooling or ventilation are attached to mechanical equipment containing a fan or blower. Vibrations, noises and rattles resulting from the operation of the fan or blower are transmitted into the metal ducts which carry the noises throughout the system. In order to isolate the vibration and noises to the source, an air-tight flexible joint, consisting of a fabric which is secured to the sheet metal on both sides, must be inserted between the equipment and the ductwork.

This flexible joint is called a “Flexible Duct Connector.” To meet every type of installation requirement, whether it be for a factory, institution, office or home; Duro Dyne offers the widest variety of flexible duct connector fabrics (U.L. Classified) and sizes; preassembled with the sheet metal permanently secured to the fabric by means of exclusive seam locks. Duro Dyne Flexible Duct Connectors are dispensed from the carton, ready to complete fabrication faster, more efficiently, and more economically than any conventional method.

Specifications:

• Type: Solvent-based adhesive
• Application: Bonds insulation to metal ductwork
• Color: Typically red
• Drying Time: Fast-drying formula
• Temperature Resistance: Suitable for HVAC applications with temperature variations
• Adhesion: Strong bonding to metal surfaces
• Application Method: Spray, brush, or roller

Key Features :

• High-Strength Bonding – Ensures secure adhesion of insulation to metal ductwork.
• Fast-Drying Formula – Reduces installation time for efficiency.
• Moisture & Temperature Resistant – Designed for HVAC systems with varying conditions.
• Versatile Application – Can be applied using a spray gun, brush, or roller.
• Solvent-Based Formula – Provides excellent tack and durability.

Usage Instructions:

• Ensure the metal duct surface is clean, dry, and free from dust, oil, or grease.
• If necessary, wipe with a suitable solvent or cleaner to remove contaminants.
• Spray Application: Use a pressure pot spray system for even distribution.
• Brush or Roller: Apply a uniform coat to both surfaces if needed.
• For best adhesion, apply adhesive at room temperature (above 50°F / 10°C).
• Allow the adhesive to become tacky before attaching insulation (varies based on temperature & humidity).
• Press the insulation firmly onto the duct surface to ensure strong adhesion.
• Full curing typically occurs within 24 hours.
