Dynafoam? Foam-In-Place Gasketing
Specification
Dynafoam Foam-In-Place Gasketing (FIPG) technology is based on mono-component Polyurethane (PUR) chemistry. Dynafoam products are physically foamed by injecting Nitrogen (N2) and curing takes place once the product is out of the foaming system in contact simply with the humidity of ambient air or under accelerated humidity and temperature conditions. Because Dynafoam products are mono-component; there is no need for metering different chemicals, no need for mixing reactive chemicals close to the dispensing gun and no need of purging material during production cycle, even for long breaks, eliminating waste that harms the environment and the cost.Overview:
The product is shipped and stored in multilayer moisture tight sealed bags contained in 20 liters pails or 200 liters drums. The drum unloader plate of the foaming system is directly pumping the material from the bag avoiding all contact of materials with ambient air.

? Enables complex 2-D and 3-D sealing designs
? Provides design freedom in terms of gasket shapes and cross sections as well as substrate interfaces
? Allows for mechanically and chemically robust gaskets
? Provides excellent adhesion to a wide range of substrates
? Very low free iso-cyanates
? Solvent free
