EXPERT LINE LOW EXPANSION Gun Foam

• the foam exhibits exceptionally good adhesion to smooth and porous surfaces, when mounting doors and windows, like PVC, masonry, concrete, brick, metal and others
• low-expansion formula prevents frame warping and facilitates full crack filling
• exhibits excellent thermal insulation and sound absorbing parameters
• cures with atmospheric moisture
• resistant to mould and fungi

• yield: up to 45 l
• skin-over time: 5÷12 min. (+20°C, RH 90%)
• workability time: 40-50 min. (at: +20°C, RH 60%)
• full curing time: 24 hours
• substrate working temperature: from +5°C to +30°C; winter version: from -10°C to +30°C;
• can temperature: +20°C;
• dimensional stability: 1.2-3% (at +40°C, RH 95%, 24 hours)

Substrate preparation:
Thoroughly clean and degrease the substrate. Before application, moisten the surface with water mist to ensure better adhesion.

Product preparation:
Before use, warm the can with foam to room temperature (optimally +20°C) by, for example, immersing the can in warm water. Shake the can vigorously for 30 seconds to thoroughly mix the ingredients. Screw the can onto the expanding foam gun.

Foam application:
Dispense product in the upside-down working position. Fill the gap to 60% of its depth, in layers of 4 cm per layer. Moisten the surface between each layer to improve good adhesion and speed up curing. Fill vertical gaps from bottom to top. Once fully cured use a knife to cut off any excess foam. When the foam has fully cured, it should be protected from UV radiation by covering it with silicon masses, plasters, paints etc.
