Built for the pros, the HandiFoam II-16 Spray Foam is an effective touch-up or repair spray foam for contractors and DIYers alike. Use with the dispensing gun and the patented ColorWise Temperature Warning nozzles to effectively seal and insulate small voids and areas, bath and hot tub insulation, and refrigeration truck and trailer repair. The ColorWise Temperature Warning nozzles change from clear to blue as a visual indication that the foam is too cold and should not be dispensed until properly conditioned. To avoid off-ratio foam and yield-loss, properly condition the chemical before spraying. This product is formulated utilizing an HFO blowing agent which is part of HandiFoam's ongoing commitment to developing foam chemistries with lower global warming impact and enhanced product performance. HandiFoam is an industry-leading brand that delivers low-pressure one- and two-component polyurethane foam sealants, adhesives, pour-in-place and spray foams. HandiFoam is built on the foundation of innovations that improve. We are committed to developing products, exclusive technologies that improve the overall product performance, safety, and experience for our customers.
