High Friction Surface Binder (K-202)

  • LOW VISCOSITY
  • LOW MODULUS
  • SINGLE COAT APPLICATION
  • USER FRIENDLY MIX RATIO
  • ASTM C-881, TYPE III, GRADE 1 Compliant
  • VDOT Epoxy Concrete Overlay Compliant

High Friction Surface Binder (HFSB) is a 100 % solids, self-leveling, primerless, low odor, epoxy coating designed to increase friction of road pavements and other surfaces by encapsulation of high friction fillers or aggregate.

The HFSB provides a convenient work life, rapid tack free time, and adhesion to road pavement materials.

The HFSB can be easily applied with a squeegee or automated methods. Normal application thickness is 30-50 mils (0.76-1.27 mm) of mixed epoxy liquids immediately followed by an aggregate broadcast to refusal. Application thickness varies depending on the porosity and roughness of the surface, and size of the aggregate used. Multiple applications may be used to obtain the desired profile.

SURFACE PREPARATION

To achieve excellent adhesion, the substrate should be clean and free of all loose or foreign materials. Oils, greases, waxes or other contaminates must be removed prior to coating. HFSB should not be applied to noticeably wet surfaces although a certain amount of dampness is acceptable.

AMBIENT CONDITIONS

Relative humidity and dew point must be determined before application to avoid adhesion failures. The dew point is used to predict the substrate temperature at which air begins to condense, in the form of water, on the substrate. Never apply a coating unless the form surface temperature is 5 °F (2.5 °C) above the dew point. This temperature difference must be observed until the epoxy coating is cured to a tack-free state.

MIXING

Add 1 part B (hardener) to 1 part A (resin) and mix for 3 minutes using a Jiffy Mixer and a slow speed drill. Mix at slow speed (less than 850 rpm) to avoid air entrainment. DO NOT mix more material than can be used within the stated working time. REMEMBER - you will have less working time at higher temperatures.

APPLICATION

The HFSB can be applied with a squeegee or automated methods.

CLEAN-UP

The HFSB, before it is fully cured (hard), may be removed from tools with warm soapy water, isopropyl alcohol (IPA), MEK or acetone.

SAFETY PRECAUTIONS

Avoid breathing of vapors. NIOSH approved, organic vapor respirators and forced exhaust are recommended in confined areas, or when conditions (such as heated polymer, sanding) may cause high vapor concentrations. Do not weld on, burn or torch the HFSB or any epoxy material. Hazardous vapor is released when an epoxy is burned

Avoid skin or eye contact. Wash skin with soap and water if contact occurs. If eye contact occurs flush with water for 15 minutes and obtain medical attention.

Read and understand all cautions on can labels and material safety data sheets before using this material.
