MasterProtect CR 170

Description

MasterProtect 170CR is a high-build, 100% solids epoxy coating. It provides resistance to harsh chemicals, including 98% sulfuric acid, and can be used as a topcoat over epoxy and polyurethane coatings.

Product Highlights

• Hard wearing-surface for durable, lowmaintenance flooring.
• Chemical resistant for excellent resistance to sulfuric acid and a wide range of industrial chemicals.
• 100% solids system for solvent free and nearly odor-free application.
• Liquid applied for seamless protection of concrete.
• Usable with aggregate broadcast for a slipresistant floor finish.

Technical Data Composition

MasterProtect 170CR is a 100% solids Novolac Epoxy

How to apply

 Surface Preparation

1.  Surface must be clean, structurally sound, and fully cured 28 days.
2. Mechanically profile the surface of both old and new concrete by shotblasting to ICRI CSP 4, then remove dust by vacuuming.
3. Prime with MasterEmaco P 130 or MasterEmaco P 160.

Priming

1. Prime the prepared substrate with MasterEmaco P 130. Apply MasterEmaco P 130 at a coverage rate of 150–300 ft2 /gallon (3.6–7.4 m2 /L). Refer to the MasterEmaco P 130 data sheet for more details or call BASF Technical Service.
2. Allow MasterEmaco P 130 to become tack free (approximately 3–4 hours) before applying MasterProtect 170CR.

Mixing

1.  Precondition all components to 70° F (21° C) for 24 hours before using.
2. Thoroughly stir each separate component (epoxy resin Part A and the hardener Part B) before mixing the 2 components together.
3. The mix ratio by volume is 2:1 (A:B). Combine 1 part B with 2 parts A in a clean, suitably sized container. Scrape the sides of the containers to remove as much material as possible to ensure accurate mixing ratio.
4. Mix the components together using a slowspeed (400–600 rpm) drill with Jiffy mixer for at least 3 minutes until uniform in color with no streaks of color in the mixture.

Application

As a coating for concrete substrates

1. Apply the mixed product to the clean, primed surface by roller or brush. Use the shortest nap roller suitable for the prepared substrate profile.
2. Backroll the coating to ensure good wetting of the substrate, uniform thickness of the coating, and removal of any roller marks.
3. Apply two 20-mil coats at the rate of 80 ft2 / gal (2 m2 /L) per coat.
4. To make the coating slip resistant, broadcast clean, dry sand into the first coat while it is wet. Apply sand to the point of saturation (approximately 80 lbs/100 ft2 [3.9 kg/m2 ]). When coating is dry, sweep excess sand and apply the second coat of MasterProtect 170CR.
5. Recoating must be done within 24 hours at 70° F (21° C). After 24 hours, mechanically abrade the entire surface of the coating and clean with acetone or xylene. Allow MasterProtect 170CR to dry and reapply the coating within 1 hour.

As a topcoat for epoxy or polyurethane floor and wall coatings

1. When applying MasterProtect 170CR over an existing coating, first conduct a test application.
2. Lightly sand the surface with medium sandpaper or a 60–80 mesh 3M screen back. Vacuum up all dust and solvent wipe floor with acetone. Allow to dry.
3. Apply the MasterProtect 170CR within 1 hour and according to application instructions.

As a trowel-down topping

1. After mixing, slowly add 2–3 parts clean, dry sand by volume to 1 part mixed MasterProtect 170CR epoxy by volume.
2. Trowel or screed the sand-modified MasterProtect 170CR to desired thickness (minimum 1/4″ or 6 mm).

Curing

Tack free: approximately 4–6 hours Traffic ready: 24 hours Fully cured: 7 days at 75° F (24° C) and 50% relative humidity

Clean up

• Clean equipment immediately after use with xylene.
• Clean hands and skin immediately with soap and water, industrial hand cleaner, or denatured alcohol.
• Cured material can be removed by mechanical means only.

For best performance

• Minimum ambient, surface, and material temperature should be 50° F (10° C) and rising at time of application.
• Acceptable service temperatures vary depending on type and frequency of chemical exposure. Contact Technical Service regarding your unique project considerations.
• For professional use only; not for sale to or use by the general public.
• Make certain the most current versions of product data sheet and SDS are being used; visit master-builders-solutions.basf.us to verify the most current version.
• Proper application is the responsibility of the user. Field visits by BASF personnel are for the purpose of making technical recommendations only and are not for supervising or providing quality control on the jobsite.
