Question
- Does FSS 42D contain VOC's?
- What is polyurea?
- Can anyone apply polyurea?
- Where can polyurea be used?
- What kind of temperatures will polyurea withstand and will it burn?
Answer
No!
Polyurea is an organic polymer that is the reaction of isocyanate with an amine terminated polyether resin, forming a plastic-like or rubber-like compound that may be used in many of the same ways as older technologies - polyurethane, epoxy, vinyl ester, neoprene; to name a few.
Polyurea requires special training and equipment for field application, whether used as joint filler or as a field applied coating. VersaFlex has an ongoing program of contractor training in place. There are qualified applicators in all regions of the U.S. and an expanding network of qualified applicators throughout the world.
As a general rule, VersaFlex polyurea can be employed to contain any substance that may be directly discharged into normal sanitary sewer systems. It may be easier to give examples of environments where polyurea should not be used. As a general recommendation for constant exposure to direct chemical attack VersaFlex polyurea products may not be installed for attack by: • Halogenated Solvents: 1. Carbon tetrachloride 2. Chloroform 3. Methylene chloride 4. Tetrachloroethane 5. Trichlorethene 6. Trichloroethane • Non-Halogenated Solvents And Ketones: 1. Acetone 2. Acetonitrile 3. Acetophenone 4. Benzene 5. Butanol 6. Camphor oil 7. Cyclohexanone 8. Diethyl ether 9. Diisobutyl ketone 10. Ethyl acetate 11. Hexane 12. Methyl ethyl ketone 13. Methyl isobutyl ketone 14. Pentane 15. Phenol 16. Toluene 17. Xylene • Acidic compounds with a total composite pH range equal to or below 4 • Basic compounds with a total composite pH range equal to or above 11 Note: Non-aqueous (anhydrous and anhydride compounds in granular, crystalline, or powder form) protected by an air drying system may be contained by polyurea. Consult VersaFlex. • Amine Attacking And Amine Containing Compounds Strong, inorganic acids, organic acid halides, aldehydes, isocyanates, organic anhydrides. 1. Aminoethylethanolamine 2. Aniline 3. Ethylamine 4. Methylamine 5. Pyridine 6. Toluenediamine
What kind of temperatures will polyurea withstand and will it burn?
VersaFlex polyureas begin to develop their physical properties within minutes of application. Among several very desirable properties are their quick gel time and their glass transition temperatures that average -40 degrees F and +480 degrees F. Heat of deflection under no load is +250 degrees F. Safe upper limit of working temperature is +350 degrees F, under no load. Polyurea will exhibit thermal shock debonding when subject to repeated periodic blasts of live steam. While polyurea has high glass transition and heat of deflection temperatures, it will burn when exposed to direct flame. It will self extinguish when flame is removed.
