DELTA FLAME RETARDANT EPICERAMICtm BISFOAM-3 A&B
FREONLESS FOAM SYSTEM
Delta EPICERAMICtm BISFOAM-3 A&B is a two-component, fast foaming, above 75°F temperature curing epoxy foaming system. The system cures to a low density, rigid, closed cell foam with outstanding non-burning properties and excellent physical properties. The cured foam, when exposed to open flames, will char with little damage to or deformation of the foam structure. The smoke emitted contains decomposition products of carbon, hydrogen, and water with only traces of fluorine or chlorine and has a low odor quality. The large mass foaming and ease of handling allows for many types of molding applications.
In addition to its fire retardant properties several other features are displayed by both the uncured and cured foam.
1. The epoxy foam is designed for in-head mixing equipment where fixed ratios are present. This provides the applicator with the ability to place large amounts of product very quickly and reduces labor and material waste.
2. DELTA BISFOAM-3 A&B can be sprayed with currently available form spray equipment. Chopped fiberglass can be sprayed along with the foam to obtain a glass reinforced foam.
3. The mixed system foams as a fast, soft rising foam with low internal forming pressures allowing the foam to be contained into specific areas without excessive pressure being generated. Lab tests indicate a maximum of 2 psi foaming pressure.
4. When the foaming action is complete, the foam is tack free. The elapsed time from start of mixing to tack free is less than 3 minutes at temperatures between 78°F and 82°F in masses of no less than 20 grams.
5. The cured foam has excellent adhesion to a wide variety of materials such as brick and other masonry products as well as lead, zinc, copper, aluminum, iron, tin, some types of polyethylene, polypropylene, kynar, epoxy, polyesters, tile, terra cotta, and marble. The foam also bonds to itself.
6. The cured foam has excellent thermal stability when exposed to open flame and excellent dimensional stability when tested for 160 hours at 300°F.
7. The thermal insulating qualities of the cured foam at a 4 pound density show a K factor of .19 BTU/hr/ft2/°F/in.
HANDLING CHARACTERISTICS:
1. Mixing Ratio:
Resin (Part A) 100 Parts by Weight
Hardener (Part B) 10 Parts by Weight
CAUTION: Both Part A and Part B of this foam system should be stirred thoroughly prior to using to ensure that no separation of ingredients has occurred.
2. The Part A of the foam system should be preheated to a temperature between 78°F and 82°F prior to in-head mixing and maintained at such temperature during injection. The resulting foam density will be a function of the temperature and the mass of the material being foamed.
The foaming action accomplished in a free foaming, unrestricted area will develop a 2.5 to 4 pound density or up to a 10 to 1 by volume expansion ratio. The foaming action accomplished in a confined area will result in an end foam product with a higher density.
CAUTION: Protective clothing and cleanliness should always be used when working with epoxy resins and hardeners. If skin contact is made, wash the area with soap and water. If the materials get into the eyes, rinse with quantities of water and consult a physician. Use epoxy resins and hardeners only in well ventilated areas and avoid breathing of vapors.
