Description
Pro Industrial™ Sher-Cryl™ HPA is an ambient cured, one component acrylic coating with excellent performance properties.
Material Use:
Pro Industrial Sher-Cryl HPA is a high-performance, one-component, water-based acrylic coating designed for both interior and exterior applications. It is ideal for commercial, industrial, and institutional environments where durability, chemical resistance, and fast dry times are required. This product is suitable for use in USDA-inspected facilities and offers excellent resistance to humidity, early rust (flash rust), and abrasion.
System Components:
Sher-Cryl HPA is typically used as a topcoat in a multi-layer coating system. Depending on the substrate, it is applied over a compatible primer or block filler. The system may include:
- Primers:
- Pro Industrial Pro-Cryl Universal Primer (for steel, aluminum, masonry)
- Pro Industrial DTM Primer/Finish or Kem Bond HS (for steel)
- Zinc Clad XI (for steel requiring zinc-rich primer)
- Loxon Concrete & Masonry Primer or Loxon Conditioner (for concrete/masonry)
- Pro Industrial Heavy Duty Block Filler (for CMU)
- ProMar 200 Zero VOC Primer (for drywall)
- Exterior Wood Primer (for exterior wood)
- Premium Wall & Wood Primer (for interior wood)
- Pro Industrial DTM Bonding Primer (for pre-finished siding)
- Topcoat:
- 2 coats of Pro Industrial Sher-Cryl HPA (Gloss or Semi-Gloss)
Applications:
Sher-Cryl HPA is recommended for use on properly prepared:
- Steel and structural steel
- Galvanized and aluminum surfaces
- Concrete, masonry, and CMU
- Wood (interior and exterior)
- Previously painted surfaces
- Equipment and machinery
- Storage tanks and piping
- Buildings, warehouses, and manufacturing facilities
- New construction projects
Application Details:
- Application Methods: Airless spray, conventional spray, brush, or roller
- Recommended Wet Film Thickness (WFT): 6.0–10.0 mils
- Recommended Dry Film Thickness (DFT): 2.0–3.3 mils per coat
- Coverage: 160–264 sq. ft. per gallon per coat (based on color and application method)
- Theoretical Coverage: 529 sq. ft. per gallon at 1 mil DFT
- Pot Life: Not applicable (single-component product)
- Dry Time @ 77°F / 50% RH / 7.0 mils WFT:
- To touch: 30 minutes
- To handle: 5 hours
- To recoat: 5 hours
- Full cure: 30 days
- Temperature Range for Application:
- Minimum: 35°F (1°C)
- Maximum: 120°F (49°C)
- Must be at least 5°F above dew point
- Relative Humidity Limit: Maximum 85%
- Clean-up: Soap and water (flush spray equipment with compliant solvent after use)
Special Notes:
- Sher-Cryl HPA is not UV stable in the same way as aliphatic polyurethanes but offers good exterior durability.
- Application above 95°F (35°C) may result in dry spray, uneven sheen, and poor adhesion.
- Application below 50°F (10°C) may result in poor adhesion and extended drying/curing times.
- During the first 16–24 hours of curing, the coating is sensitive to rain, dew, and high humidity.
- For best performance, stripe coat welds, crevices, and sharp angles.
- Gloss and semi-gloss finishes are available; gloss provides higher reflectivity and sheen.
- VOC content is compliant with most regulations (242 g/L or 2.02 lbs/gal for Extra White base).
- Not compliant with SCAQMD and LEED v4 emissions requirements.
- Surface preparation is critical: follow SSPC standards for steel, aluminum, and galvanized surfaces.
- For concrete and masonry, ensure surfaces are cured for at least 30 days and free of contaminants.
- For CMU, use a block filler before topcoating.
- For previously painted surfaces, test adhesion with a patch test before full application.
- Not recommended for immersion service or continuous water exposure.
This product is a versatile, durable, and fast-drying acrylic coating suitable for a wide range of commercial and industrial applications, especially where ease of use and water-based systems are preferred. It performs well as part of a complete Sherwin-Williams system when paired with the appropriate primer for the substrate.
