Application Notes

Preparation

• Ensure suitability of the product prior to use
• Protect all surrounding areas and substrates which are required to remain free of FF197
• Surfaces must be solid and stable
• Remove all loose particles, dust and grease
• A speedier cure can be attained by moistening the substrates if needed

Application

• Immediately prior to use shake canister vigorously at least 20 times
• Remove the protective cap and screw onto the Nullifire PU foam gun or use the nozzle provided
• Fill approximately 80% of the required depth of the cavity because the foam will expand
• Work upwards on all vertical surfaces
• The foam is set in approximately 1 hour (depending on temperature and humidity); excess can be trimmed with a suitable cutting knife
• Applying a light misting of clean water between each layer before subsequent application will permit faster cure and increase density

Please see the Product Data Sheet for detailed application and safety information before use.

Limitations

• As with all PU foams, FF197 will not adhere to Teflon, polyethylene or silicone coated surfaces
• The cured foam is adversely affected by UV light and should be covered with a suitable sealant such as FS703 silicone or FS701 intumescent acrylic.
