Sher-Clear 1K Waterborne Acrylic Clear Coat B66C00380 Semi-Gloss

Applied to existing waterborne coatings and select solvent-based coatings, Sher-Clear™ provides color and gloss protection over newly applied industrial water-borne coatings and select solvent-based coatings.

Sher-Clear™ is a one-component (1K), waterborne, UV-resistant acrylic clear coat designed to provide gloss and color protection over newly applied or existing industrial waterborne coatings and select solvent-based coatings. It is primarily used as a protective topcoat to extend the weathering properties of base coatings in exterior environments.

Sher-Clear™ is used as a final clear coat in a multi-layer coating system. It is compatible with a variety of base coats, including both waterborne acrylics and certain alkyds. It does not require a separate primer when applied over compatible coatings but must be applied over a properly prepared and sound surface. It is not to be tinted and should be hand-stirred before use.

Sher-Clear™ is recommended for exterior use on:

- Equipment and machinery

- Exterior storage tanks

- Piping and structural steel

- Corporate logos and signage

- Amusement park structures

- USDA-inspected facilities (suitable for use)

- Application Methods: Brush, roll, or spray (airless or conventional)

- Recommended Wet Film Thickness: 3.0 – 5.5 mils

- Recommended Dry Film Thickness (DFT): 1.1 – 2.0 mils per coat

- Maximum DFT per coat: 2.0 mils (exceeding this may result in a cloudy or milky appearance)

- Coverage: 286–520 sq. ft. per gallon depending on film thickness; theoretical coverage is 572 sq. ft. per gallon at 1 mil DFT

- Reducer: Water (up to 10% by volume if needed)

- Drying Times at 3.0 mils wet, 50% RH:

- Touch: 45 minutes @ 77°F

- Handle: 1 hour @ 77°F

- Recoat: 2 hours @ 77°F

- Full Cure: 14 days @ 77°F

- Pot Life: Not applicable (1K product)

- Shelf Life: 12 months unopened

- VOC Content: 81 g/L (0.68 lbs/gal)

- Volume Solids: 36 ± 2%

- Weight Solids: 38 ± 2%

- Weight per Gallon: 8.62 lbs

Environmental and Application Conditions:

- Temperature Range for Application: 50°F (10°C) to 120°F (49°C)

- Humidity Limit: Maximum 85% RH

- Surface Temperature: At least 5°F above dew point

- UV Resistance: UV-resistant (suitable for exterior exposure)

- Do Not Apply Over: White or very light pastel-colored alkyds

- Surface Preparation: All surfaces must be clean, dry, and free of contaminants. Glossy surfaces should be dulled. For previously painted surfaces, a test patch should be applied and evaluated after one week for adhesion.

Compatible Base Coats:

Sher-Clear™ is designed to be applied over the following coatings:

- Acrylics:

- Bond-Plex Waterbased Acrylic

- Metalatex Semi-Gloss

- Pro Industrial Acrylic

- Pro Industrial DTM Acrylic

- Pro Industrial Multi-Surface Acrylic

- Sher-Cryl

- SprayLastic

- Alkyds (except white/light pastel):

- Industrial Enamel

- Industrial Enamel HS

- Pro Industrial Urethane Alkyd

- Pro Industrial Waterbased Alkyd-Urethane

- Steel Master 9500

- Do not apply more than 2.0 mils dry film thickness per coat to avoid cloudiness.

- Always test compatibility with existing coatings by applying a 2–3 sq. ft. test patch and evaluating adhesion after one week.

- Application of a clear coat may alter the appearance of the base color—test before full application.

- Not suitable for use over white or very light pastel alkyd coatings due to potential discoloration.

- Clean tools and equipment with soap and warm water immediately after use.

- For mildew-prone surfaces, pre-clean with a bleach solution (1 part bleach to 3 parts water), rinse thoroughly, and allow to dry before application.

Sher-Clear™ is a versatile, fast-drying, and UV-resistant clear coat ideal for protecting and enhancing the durability of industrial and architectural coatings in exterior environments.
