ARBOPROTECT Pro B2 Elastic Air-Tight Foam
Main Applications
ARBOPROTECT Pro B2 Elastic Air-Tight Foam is suitable for the installation of window and door frames, sealing and connection of joints including movable or pressure-sensitive joints, insulation of penetrations, sealing of thermal and acoustic insulation boards, and reducing the impact of thermal bridges.
Key Performance Attributes
Permanently elastic performance.
Near-zero curing pressure and low post expansion help avoid deformation of building elements.
No shrinkage.
Suitable for all season use, from -5 °C up to +30 °C.
Excellent air tightness and thermal insulation properties.
Application conditions
Air temperature during use should be between -5 °C and +30 °C. Make sure the ambient temperature stays within this range until the foam has fully cured.
Can temperature during application should be between +5 °C and +25 °C, with best results at +20 °C.
The product should be conditioned 6 hours prior to use to obtain maximum volume output and optimal physical and mechanical properties.
Surface preparation
Remove dust, loose particles, ice and oil stains from the surfaces.
Moisten dry substrate, only at temperatures above zero, to ensure better results.
Protect adjacent surfaces with paper, plastic film or other suitable material.
If needed, add additional shield outside for weather protection against rain, snow, wind and similar conditions.
Application method
Shake the can vigorously at least 20 times. Remove the cap. Hold the foam can in upright position with valve up. Screw the can tightly to the gun by holding the gun handle with one hand and turning the can with the other hand.
Do not aim the gun at people. Avoid screwing the can to the gun with the valve upside down. Do not screw the gun to the can. Do not bend or turn the can during screwing.
Hold the can upside down when extruding the foam. Foam output can be adjusted with the gun trigger and adjustment screw.
Fill joints up to approximately 70%, as the foam expands.
In case of larger joints, apply foam in several layers and moisten slightly between each layer to ensure better results.
Excess foam can be cut after it has fully cured.
Cleaning
Uncured foam can be removed with acetone.
Cured foam can be removed mechanically.
Curing time
| Temperature (°C) | Time (hours) |
|---|---|
| +20 | 8 |
| +5 | 12 |
| -5 | 24 |
Packaging
750ml can, 12 per box.
Storage conditions and shelf life
Shelf life is 12 months from production date if stored in unopened packaging in a cool and dry place at +5 °C to +30 °C.
Do not expose to temperature over +50°C, and do not keep near heat sources or in direct sunlight.
Store and transport in upright position.
Secure cans before transport.
Limitations
The foam will not adhere to Teflon, polyethylene, polypropylene and silicone surfaces.
It is not advisable to unscrew the gun from the foam canister intermittently. The foam should be used in a way that the gun is screwed on once.
Cured foam is sensitive to UV-light and direct sunlight and therefore must be covered with suitable opaque sealant, filler, paint or other material.
Do not cover before the foam has fully cured.
Health & safety
Pressurized canister.
Use only in well-ventilated areas.
Do not smoke during application.
Use PPE when necessary.
Keep out of the reach of children.
