Adhesive for K‑flex insulation K-FLEX K-414 0.50 L (MPN 850CL020002)

K-FLEX K-414 adhesive is a solvent-based bonding agent designed for joining K‑flex elastomeric insulation and similar flexible insulation materials. Supplied in a 0.50 L container, the formulation provides rapid tack and strong adhesion to typical HVAC substrates, enabling secure fixing on ducts, pipes and hot or cold surfaces where compatibility with K‑flex products is required.

Advantages

The adhesive offers fast initial tack, good shear strength and a durable bond that resists movement of flexible insulation on pipes and ductwork. Its formulation is developed to be compatible with K‑flex elastomeric materials, reducing the risk of deterioration of the insulation surface. The 0.50 L size is suitable for targeted repair work and smaller installation tasks, providing controlled application and minimal waste.

Suitable for

• Bonding K‑flex elastomeric insulation on HVAC ducts
• Fixing insulation on chilled and hot water pipes
• Joining seams and overlaps of flexible insulation sheets
• On-site repairs and patching of insulation systems

Key specifications

• Container volume: 0.50 L
• Compatibility: formulated for elastomeric flexible insulation
• Application temperature range: suitable for typical HVAC installation conditions (ambient and surface temperatures within normal service limits)
• Adhesion properties: rapid tack with durable bond for shear and peel loads encountered in pipe and duct insulation
• Form: solvent-based adhesive for brush or roller application

How to use

Ensure surfaces are clean, dry and free of dust, oil or loose particles before application. Apply an even coat of adhesive to one or both mating surfaces depending on joint type; allow the adhesive to become tacky to the touch according to drying time appropriate for ambient conditions, then press the insulation into place and maintain contact until the bond develops. For seams and overlaps, ensure continuous contact along the joint. Clean tools and any accidental spills with a suitable solvent before the adhesive cures.

Usage recommendations

Use in well-ventilated areas and follow manufacturer guidance for safe handling of solvent-based products. Store the adhesive in a cool, dry place away from ignition sources and out of reach of children. For best results, test adhesion on a small area when bonding non‑K‑flex materials and follow any project-specific thermal and fire-safety requirements.
