Information

Fortis AD5113 is a single-component, moisture-curing polyurethane laminating adhesive for composite and sandwich panels. Its low viscosity allows spray, roller or brush application, while fast green strength supports efficient panel assembly.

Suitable applications include stainless steel benchtops, caravan and RV panels, truck and transport panels, insulated panels and rubber matting. It bonds substrates including stainless steel, Colorbond® steel, polystyrene foam, timber and selected composite materials.

Confirm substrate compatibility and production settings through a trial before use. Coverage, assembly time and pressing requirements depend on the materials, application method, temperature and humidity.

Material

Single-Component Moisture-Curing Polyurethane

Advantages

Single-component polyurethane adhesive
Fast green strength
Short clamp time
Low-viscosity formulation
Spray, roller or brush application
Excellent adhesion at low application rates
Bonds dissimilar materials
Suitable for metal-to-foam lamination
Excellent heat resistance
Suitable for industrial panel manufacturing
No mixing required

Product Application

Apply to clean, dry surfaces free from oil, dust and other contaminants. Apply evenly by spray, roller or brush. General coverage is approximately 100–400 g/m²; for spray application, the recommended rate is 100–200 g/m² to one bonding face.

Assemble within the open time of less than 10 minutes at 20°C and 65% relative humidity, then press to maintain uniform contact. Confirm the required pressing time through production trials, as temperature, humidity, substrates and pressing conditions affect bond development.

Do not use application equipment with aluminium components in contact with the adhesive. All components contacting AD5113 must be stainless steel. Refer to the current Technical Data Sheet and Safety Data Sheet before use.

Surfaces

FORTIS AD5113 is suitable for bonding a wide range of materials used in industrial lamination and panel manufacture, including:

Stainless steel
Colorbond® and coated steel
Polystyrene foam
Timber and wood-based panels
Rubber
Composite panels
Selected foams and porous substrates

AD5113 is particularly suited to applications requiring bonding between dissimilar materials, including metal-to-foam and metal-to-porous substrate laminations.

All surfaces must be clean, dry and free from oil, grease, dust and other contaminants. Metals may require additional surface preparation to achieve optimum adhesion.

Compatibility should be confirmed before bonding coated metals, plastics, foams or unfamiliar substrates.
