Chemical Resistant Coating - Sikagard®-616

Versatile Epoxy for use as a Primer, High Build Protective Coating and for Decorative Quartz and Flake Application

Sikagard®-616 is a 2 component, low odor, 100 % solids, epoxy resin coating system primarily designed for high build coatings and decorative quartz applications. Sikagard®-616 may be used as a clear primer.

• Tough, smooth, non-porous surface is easy to clean
• Durable, impermeable and seamless
• Attractive, high gloss, reflective coating
• Good chemical and mechanical resistance
• 100 % solids as supplied
• Easily applied with brush, roller or squeegee
• Good Abrasion Resistance
• Excellent Impact Resistance

Usage

Sikagard®-616 is ideal as a broadcast clear, low odor top coat or intermediate coat over decorative quartz or vinyl flake floor broadcast systems. Sikagard®-616 can also be top coated with an aliphatic urethane when increased chemical and abrasion resistance are required. When used as a primer, Sikagard®-616 can be considered where 4 % moisture content by mass (pbw - part by weight) is measured on concrete substrate with Tramex® CME/CMExpert type concrete moisture meter.

Coverage

Smooth finish coating:

Prime Coat: 160-200 ft²/US gal (3.9-4.9 m²/L) at 8-10 mils (0.20-0.25 mm) wet film thickness (w.f.t.)

Wear coat: 100 - 133 ft²/US gal (2.5-3.2 m²/L) at 12-15 mils (0.30-0.38 mm) wet film thickness (w.f.t.).

Application Steps

MIXING

Mixing Ratio - 1.5 : 1 by volume. Premix each component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes using a low speed drill (300-450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce any air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.
Do not mix more material than can be applied within the working time limits (i.e. pot life) at the actual field temperature.

APPLICATION

As primer: Apply Sikagard®-616 by squeegee at the rate of 160 - 200 ft2/US gal (3.9-4.9 m2/L) at 8-10 mils (0.20-0.25 mm) wet film thickness (w.f.t.) and back roll with pressure after 15 minutes. Coverage will vary depending on the porosity of the prepared floor. Product has a limited Pot Life, see Typical Data. Do not apply by dipping roller into mixing container. Pour a bead of product in the form of a ribbon on the surface to be coated, then spread with squeegee and back roll. Ensure that the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate. If necessary, apply an additional coat to ensure the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.

As sealer/intermediate: Sikagard®-616 is applied with a 40 mil (1 mm) notched squeegee over a smooth surface and a flat squeegee over a rough or decorative quartz surface. Back rolling is typically done with an 18 inch (455 mm) wide 3/8 inch (10 mm) short nap, solvent-resistant roller cover. Back roll the Sikagard®-616 only to level the squeegee applied material. Over-rolling and late back rolling may cause bubbling and leave roller marks.
