Product Overview
Self-adhesive hangers with a 90mm overall pin length complete with galvanised spring-steel locking washer. Designed to fix insulation to smooth substrates such as air ducts, attenuators, chambers, and enclosures without drilling.
Each hanger consists of an aluminium shank securely factory-mounted to a 50mm × 50 mm galvanised steel base, coated with high-quality white, cross-linked, closed-cell polyethylene foam adhesive.
Installation is quick and simple: impale the insulation and secure it with the locking washer. Full bond strength is achieved after 24 hours.
Ideal for applications requiring medium projection, these hangers are suited to medium insulation thicknesses and standard quilt build-ups, with a precise overall length of 90mm.
Features & Benefits
- Adhesive base construction: 50×50 mm galvanised steel plate, 0.4 mm thick, bonded with 1mm white cross-linked closed-cell polyethylene foam coated both sides with modified acrylate adhesive; siliconised paper liner for clean release.
- Pin specification: 2.7mm (12 ga) aluminium shank firmly mounted to the base for reliable impalement and retention of insulation layers.
- Washer compatibility: Supplied with CL 24-32 bevelled-edge locking washers, manufactured from 0.4mm thick galvanised spring steel (32 × 30 mm), providing secure and reliable mechanical clamping.
- Length: 90mm length provides practical projection for thicker liners and denser quilt build-ups where increased stand-off is required.
Applications
- Duct liners: Fastening medium-to-heavy duct liner to smooth sheet-metal duct walls and plenums.
- Equipment enclosures: Fixing insulation inside AHU panels and casings with moderate to deep clearance.
- Acoustic wraps: Retaining medium-weight acoustic quilts on larger branches and take-offs.
- Foil-faced laminates: Clamping multi-layer foil-faced thermal membranes where longer projection is preferred.
Installation Guidance
- Surface condition: Substrate must be clean, dry, and free of dust, grease, oil, or loose matter; do not use degreasing agents.
- Application temperature: Install within +15 °C to +25 °C for optimum adhesive wet-out.
- Placement: Remove the siliconised liner without touching the adhesive, position, and press the full base area firmly.
- Fixing the insulation: Impale insulation immediately and drive the locking washer down to clamp; full bond develops after 24 hours.
- Finishing: Trim or cap the exposed pin as required to prevent sharp protrusions and protect adjacent materials.
Compliance & Performance
- Materials:
- Base formed from 50×50mm galvanised steel, 0.4 mm thick, providing a rigid and corrosion-resistant mounting platform.
- Shank manufactured from 2.7mm (12 ga) aluminium for light weight, ease of impalement, and long-term stability in service.
- Adhesive layer composed of 1mm white, cross-linked closed-cell polyethylene foam coated on both faces with modified acrylate adhesive to deliver permanent, pressure-sensitive bonding.
- Liner of siliconised paper ensures clean release during installation.
- Locking washer supplied in galvanised spring steel, CL 24-32 pattern, 32×30 mm with 0.4 mm thickness and bevelled edges for secure grip and smooth seating.
- Adhesion performance:
- Modified acrylate adhesive demonstrates high initial tack and long-term bond strength.
- When tested to FINAT-TM 1 on stainless steel with a 50 µm polyester film, peel adhesion exceeds 18 N per 25 mm after 1 minute, with substrate tearing observed after 20 minutes and 24 hours, confirming cohesive bond integrity.
- FINAT-TM 8 shear testing shows sustained load resistance exceeding 150 hours at 23 °C and 1 hour at 70 °C, indicating reliable adhesion across typical service temperatures.
- Service conditions:
- Optimum installation temperature is between +15 °C and +25 °C to achieve full adhesive contact and bond formation.
- Once applied, the assembly remains serviceable within a holding temperature range of −40 °C to +80 °C without adhesive degradation.
- Storage life is up to 2 years when kept in a dry environment at +10 °C to +30 °C and approximately 50% relative humidity.
- Surfaces must be clean and dry - avoid the use of degreasing products and prevent exposure to chlorinated, cetonic, or ester-based solvents, which may compromise adhesive performance.
- Limitations: Not for contact with chlorinated, cetonic, or ester solvents; verify substrate compatibility and bond on site.
- Important note: Information is guidance based on tests and experience; ensure suitability for purpose and follow system fire/hygiene requirements; handle sharp pins with appropriate PPE.
