3 3 Total Floor Coating System Primer (A)–Often used with broadcast systems, and are highly recommended for any application on concrete (including damp/green). Can be pigmented if no base coat is used. Base coat or Mid coat – Self-level slurry (B) (50-60 mil dry); unfilled clear for single/double broadcast (C) (10-20 mil dry) or coating (5-10 mil dry). Top coat or Seal coat (D)– Applied as a clear coat on top of base or mid coat (10-20 mil dry). A D B C A D Self- leveling System Single / Double Broadcast System

4 4 Attributes of a Total Floor Coating System Great Handling Properties –Long working time –Rapid property development Green –Environmentally friendly –Zero to low VOC –Low odor Excellent Performance Properties –Good adhesion to concrete (dry and damp) –Good recoatability –Fast return to service –UV stability –Chemical / stain resistance –Impact resistance –Abrasion resistance

6 6 Advanced Thermoset Technologies - Polycarbamide Technology Key attributes Very rapid cure speed Low temperature cure Excellent UV resistance Thick films in 1 pass (up to 20 mils) Good stain & chemical resistance High abrasion resistance High impact resistance High gloss Current Limitations Ability to control gloss levels for topcoat applications

7 7 High Gloss is nice, but… Formulators want flexibility in providing topcoats with wide gloss range -Low gloss coatings hide flaws better -Surface wear are not easily seen with satin finish -Customer preference Current Thermoset Technologies used for high and low gloss topcoats -Solventborne Polyurethanes -Waterborne Polyurethane

8 8 New Novel Polycarbamide Technology Unique new amine curing agent designed for use with aliphatic isocyanate resins in high performance flooring applications The new Polycarbamide technology, Amicure® IC-322 retains the excellent UV stability and durability of our current commercial offerings, and plus builds in an exciting new Feature: -Formulating flexibility gives the formulator important new latitude to: Customize finish between High Gloss and Satin Low gloss finish is obtained by adding a specialized commercial matting agent in the formulation -Brings in some VOC, but still <100 g/L

15 15 Advanced Thermoset Technologies Conclusion A new amine curing agent, Amicure IC-322 has been developed for use in Polycarbamide coatings. -Formulating flexibility gives the formulator important new latitude to customize gloss between High Gloss and Satin finish. The low gloss Polycarbamide formulation provides improved benefits over traditional low gloss thermoset technologies: -Rapid property development -Early chemical and water resistance -Ability to apply thick films in one pass -Can apply satin finish at lower temperatures
