Product Description

The DDP Specialty Electronic Materials 99108824 is a 12-ounce minimal expanding foam sealant designed to fill, seal, and insulate gaps, cracks, and holes up to 1 inch in size. Sold in cases of 12 cans, it uses a smart dispenser system that is reusable and allows precise, controlled application in any direction. The foam cures rigid and waterproof, making it suitable for both interior and exterior use. Licensed contractors and experienced trade professionals use this product when air-sealing penetrations, blocking drafts, and reducing energy loss around building envelopes.

This sealant is built for multi-use applications across residential and light commercial jobsites. It is well-suited for sealing around pipe penetrations, conduit entries, window and door frames, masonry openings, and similar gaps encountered in HVAC rough-in, plumbing, and electrical work. The formula adheres to wood, metal, masonry, glass, and most plastics. Once cured, the foam is paintable, sandable, and stainable, allowing finished surfaces to be restored without visible patching.

Installation Notes

This product is typically applied by HVAC technicians, plumbers, electricians, and general contractors during rough-in or finishing stages. Shake the can thoroughly before use and test the dispenser before applying to the work surface. Wear gloves and eye protection, as uncured foam bonds aggressively to skin and surfaces. Refer to local building codes and energy-compliance requirements, such as IECC air-sealing provisions, when using foam sealant in envelope penetrations.
