1. KEFA Coating Presentation to New York City Transit 2 Broadway January 25, 2007 Robbie Wood and Regis Doucette 201.664.5487

2. KEFA Coating We create dry surfaces We improve the indoor climate Micro porous coatings

3. KEFA Pedigree On the market for over 30 years Product applied over 400,000,000 sq ft In over 40 countries First application 1975 - Still working Products are based on 3 patents Developed in co-operation with Swedish, US, UK Universities

4. What is a KEFA Coating ? A microporous coating Water based Harmless to health Harmless to environment It works forever It works automatically/passively Not a 1-use like intumescents

5. Some KEFA Benefits KEFA – Condensation Protection KEFA – Mold Protection KEFA – Facade Paint KEFA – Heat Protection ALL NATURAL NON-CHEMICAL

6. KEFA Coating x 500

7. Microporous structure provides interesting properties Condensation protection Improves rust protection + detects corrosion Mold remediation Insulates Dries out fresh construction Improves insulation Does not attract dust and dirt Noise damping

8. KEFA Coatings Speed up evaporation

9. Dew point with dry periods between condensation periods KEFA Coating requires a cyclic condensation process

10. Condensation protection Jaeger Arrow

12. The MP structure provides interesting properties Condensation protection Improves Rust Protection. Detects corrosion Mold Remediation Insulates Dries out construction Improves insulation Does not attract dust and dirt Noise damping

13. KEFA Coating with sand grain

14. KEFA Coatings Adsorption/evaporation capacity

15. Metal KEFA Coating Surface temperature over dew point No condensation, No corrosion

16. KEFA Coating Metal Surface temperature at dew point Condensation forms on surface Corrosive stage No condensation on KEFA Coating

17. KEFA Coating Metal Surface temperature under dew point Condensation water dripping from metal The drop is more corrosive than the film.

18. KEFA Coating Metal Surface temperature under dew point Condensation forms also between metal and KEFA Coating. Condensation water is absorbed and spread evenly in the coat. No corrosive drops

19. KEFA Coating Metal Surface temperature over dew point

20. KEFA Coating Metal Surface temperature over dew pooint Dripping stops. Water film still corrosive KEFA Coating surface dries considerably faster than metal surface. No corrosion

21. KEFA Coating Metal An air stream speeds up evaporation

22. KEFA Coating Metal An air stream speeds up evaporation KEFA Coating dries very fast

23. Condensation on Concrete Differs from condensation process of metal Concrete is a poor heat conductor

24. Concrete KEFA Coating Concrete temperature at air temperature Day. High temperature No condensation

25. Concrete KEFA Coating Evening. Air temperature sinks No condensation Concrete temperature over air temperature

26. Concrete KEFA Coating Concrete temperature over air temperature Night. Air temperature sinks further No condensation

27. Concrete KEFA Coating Morning. Air temperature rises Condensation forms on concrete Condensation forms between concrete and GT Concrete temperature below air temperature

28. Concrete KEFA Coating Concrete temperature under air temperature Condensation water absorbed by KEFA Coating Late morning. Air temperature rises

29. Concrete KEFA Coating Concrete temperature at air temperature Condensation water evaporates KEFA Coating surface dries out rapidly Noon. Air temperature rises further

32. Condensation protection Helicopter Hangar, Norway

33. Condensation protection Aircraft Hangar, Norway

34. Rust Protection Water Supply Berlin

36. Rust Protection Reduced Maintenance Norwegian Ferry

37. The MP structure provides interesting properties Condensation protection Improves Rust Protection. Detects corrosion Mold Remediation Dries out construction Improves insulation Insulates Does not attract dust and dirt Noise damping

38. Why avoid mold? Mold looks bad and creates smell Mold is an early step in the degradation process Mold can produce mycotoxins Dangerous to your health

39. Conditions for growth of mold and other organisms Presence of spores Average over the year >3 000/sqft air Nutrition = all organic material Construction material, dust, dirt, pollen Free water Condensation, construction water, leakage water Time and temperature

44. What Kefa Does Not Do

45. Kefa Also Does Not Cost extra money over time Require extra coats of coating every year And we do not work as designed if Kefa is top coated by any other coating that would bury our special coating underneath, thereby defeating the purpose of preventing condensation from humid air There are no natural or induced cycles of drying in the environment (e.g. HVAC)

46. Cycle Is Important !!!

47. Why Kefa -- ABC’s A lways work—no power, no “one time only” reaction like intumescent coatings, always “on” B eautification– avoid unsightly mold, rust, broken concrete, flaking paint C ost Control from elimination of problems such as recoating requirements, damaged substrates from water, operational interuptions while fixing condensation problem, other….
