Expanding Foam is a single component, moisture cure, polyurethane construction foam manufactured in compliance with the requirements of ISO9001:2008.
Excellent adhesion to a wide variety of building materials such as brick, concrete, metal and PVC-U.
Application and ambient surface temperature range: +10°C to +30°C.
Can / applicator temperature range: +10°C to +30°C (+20° for optimal performance).
Shelf life: 12 months, always store and transport in an upright position (in order to avoid blockage of the valve), in cool dry conditions between +5°C and +30°C.
Note: Carefully read the health and safety information contained in the material safety data sheet before use.
Before use: put on protective gloves.
Surface preparation: All surfaces must be clean, and free from oil, grease and loose materials.
Spray / moisten surfaces with clean water before use as this will improve both expansion and adhesion of the product.
Shake the can of foam thoroughly (for at least 30 seconds) before application in order to thoroughly mix the foam components.
Screw the applicator onto the can. Only using the can upside down, with the valve facing down: commence foaming at the lowest point of the joint and proceed carefully until familiar with the extrusion rate. Fill the cavity about half full of foam as post expansion will totally fill the cavity.
After application the foam can be cut as soon as it has cured. Uncured foam can be removed using acetone or PU foam gun solvent but care must be taken not to damage surfaces.
Expanding Foam must be protected from exposure to UV light after curing (e.g. with paint or plaster). Failure to do so will degrade the foam.
The rate of cure is fully dependent upon temperature and humidity. Low temperatures and humidity will slow the rate of cure. Poor adhesion to low surface energy materials such as PE, PP, PA, silicone and PTFE can be expected.
Expanding Foam is part of a full range of sealants and tapes designed for the professional user.
