Ottopol KX-99

Ottopol KX-99 is a hydroxyl-functional cationic acrylic solution polymer that crosslinks with polyisocyanates and epoxy silanes at room temperature. With the combination of polyisocyanate and epoxy silane, the fastest and most resistant coating can be formulated. We recommend a maximum of 20% epoxy silane and 20% polyisocyanate based on solids. This product undergoes ambient curing very quickly, and in less than one hour the film will have water resistance. Allowing the film to cure for two hours will result in a film that has over 100 double rubs of acetone resistance. Detergents and cleaners will not remove this film, and the final dried film resists staining.

Starting Point Formulation “A” Two Component system

Part A

Ottopol KX-99 78.8
Water 9.1
*BYK 3450 0.1

In 2 hours ambient cure, the film will have over 100 double rubs acetone resistance

Part B

**AP Silane 51Epoxy Silane 7.0
***Bayhydur 305 4.7

Mix components in the order listed for 30 minutes. Resulting viscosity will be 25-30 seconds #2 Zahn Cup. The Masurf FS-2800 is a fluorocarbon wetting agent and is quite effective with this system.

Polyisocyanate Free Formula

Ottopol KX-99 is a Hydroxyl Functional Cationic Acrylic Solution Polymer. This polymer will crosslink at room temperature with Dow Corning Epoxy Silane Z-6040. We recommend a maximum of 20% Silane based on resin solids. The ambient dried film will have excellent resistance to solvents, such as, MEK, Acetone and IPA. Detergents and cleaners will not remove this film. Water resistance is excellent. The dried film will also resist staining.

Technical Details & Test Data

Performance and Attributes of Formulated Product

For concrete coatings the cured film resists the following:

Gasoline, Motor Oil, Anti-freeze, Brake Fluid and Alkaline Cleaners commonly used for concrete and Hot Tire Mark.

Heat Seal Test: 230 Celsius (446 F) @ 45 psi for one second face to face: Pass

The crosslinked and cured film exhibits high heat resistance while remaining flexible and will not crack when applied to thin film surfaces such as Mylar. Folding the Mylar in half will not crack the film or have any loss of adhesion.

Hard Tough Mar Resistance Film:

  • Pencil Hardness: Surpasses 6H
  • Konig (Pendulum): 163 seconds
  • Konig (Pendulum) addition of Silica to coating: 173 seconds

Cure Rate to Achieve Chemical Resistance at Ambient Temperatures  

  • Starting Point Formula “A”: 2 Hours
  • Starting point formula “B”: 72 Hours
  • Starting point formula “C” : 14 Hours

Pot Life of Wet Sample  

  • Starting Point Formula “A”: 8 Hours
  • Starting point formula “B”: 72 Hours
  • Starting point formula “C”: 14 Hours

Chemical Resistance (Ambient Cure)  

  • 150 Double Rubs MEK:  Pass
  • 150 Double Rubs Acetone: Pass
  • 150 Double Rubs Isopropyl Alcohol:  Pass

Differences Between the Polyisocyanate Free, the Polyisocyanate containing Formula  

The biggest difference is the cure cycle. Formula “A” will have solvent resistance in 2 hours, Formula “B” takes 72 hours and Formula “C” takes 14 hours. Formula “B” and “C” would be the safest and friendliest because the epoxy silane has FDA 177.1390 approval for direct contact with food as a component of a coating that sees over 350 Fahrenheit and contains no polyisocyanate. Our acrylic polymer KX-99 has no hazards, with the exception of a small percentage of Isopropyl Alcohol and Acetic Acid.
