Foamfix Hodgson Gun Grade PU Expanding Foam (750ml)

A single component, moisture cure, polyurethane construction foam suitable for use on a wide range of sealing and gap filling applications.

Suitable for use in the fixing of window and door frames Foamfix can reduce the number of mechanical fixings required whilst also increasing the rigidity of the structure. Excellent adhesion to a wide variety of building materials such as brick, concrete, metal, wood, stone, plaster and PVC-U. Foamfix can also be used for sealing of pipe penetrations and wall, roof and floor joints.

Gun applied for added control and ease of application with reduced waste. Foamfix Cleaner is also available for cleaning any uncured foam and the applicator gun.

Key Features

• Low post expansion
• Fast curing
• High adhesion
• High thermal and acoustic insulation properties
• Weatherproof and will not rot
• Totally cured foam is chemically inert

Properties

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

Instructions

Before use: Consult Safety Data Sheet 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.
When cleaning the PU Foam Gun: unscrew the can of Foamfix from the gun. Press the gun trigger to release pressure to remove any residual foam from the gun. Fix the spray nozzle onto the Foam Solvent valve and spray the valve of can and the gun adapter to remove any Foamfix residue. Remove the nozzle and screw the can of Solvent Cleaner onto the gun. Press the gun trigger several times to clean any uncured Foamfix from the gun, taking care to be spraying away from you into a suitable container. Spray until clear fluid starts flowing.

Note: Foam Solvent is only suitable for dissolving uncured one part PU aerosol foam. Foam Cleaner is not suitable for use on polystyrene, PVC and other plastics, testing is required prior to use. Foamfix 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 dependant 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.
