STAIN RESISTANT ADDITIVE WATER BASED
GSRC 220
Aqueous stain-resistance additive for improving water repellency, oil repellency, stain resistance and stain release in coatings, sealers and construction materials.
Build stain release into water-based surfaces.
GSRC 220 is an aqueous fluorinated polyurethane dispersion designed to provide stain resistance and release characteristics to coating formulations, sealers and construction materials. It can be incorporated into compatible acrylic and urethane systems for indoor and outdoor use.
Its surface-modifying polymer helps cured materials repel water and oil, reducing the tendency of stains to wet, penetrate and anchor to the surface.
Protection without changing the application platform.
GSRC 220 allows formulators to enhance existing aqueous coatings and construction products with relatively small formulation changes.
Incorporate in Water
Dilute with water or water-miscible solvent under agitation to the required solids.
Build the Film
Apply the compatible coating, sealer or construction formulation uniformly.
Modify the Surface
The fluorinated PUD contributes low-energy functionality during film formation.
Resist & Clean
Water, oil and staining liquids wet the surface less strongly and release more readily.
Water Repellency
Raises water contact angle and reduces wetting of compatible cured surfaces.
Oil Repellency
Improves resistance to low-surface-tension oily stains and hydrocarbon-based soils.
Stain Resistance
Helps prevent stains from spreading and penetrating the coating or sealer.
Stain Release
Supports easier cleaning and removal of deposits from the treated surface.
Aqueous Compatibility
Compatible with water and water-miscible solvents for broad water-based use.
Indoor & Outdoor Use
Suitable for evaluation in both interior and exterior coating applications.
Advancing Water Contact Angle
Higher advancing water contact angle indicates improved water repellency.
Advancing Hexadecane Contact Angle
Higher hexadecane contact angle indicates improved repellency to oily, low-surface-tension liquids.
Average Visual Scaling Rating
Average ratings: uncoated 0.5, 0.7, 1.0, 2.0, 2.0; coated 0.0, 0.0, 0.0, 0.3, 0.3 at 10-50 cycles.
Cumulative Mass Loss at 50 Cycles
Average source values after 50 cycles; coated replicates were 0.00, 0.01 and 0.00 lb/ft².

Recommended active solids for coatings and sealers.
Broader source range: 0.2-3.0% active solids for acrylic and urethane coating evaluation.
Formulation positioning
- Coatings & Sealers — Start within 0.2-1.0% active solids.
- Broad Formulation Screen — Source permits 0.2-3.0% active solids depending on system.
- Concrete Cure & Seal — Source test used approximately 3% GSRC 220 solids with 25% acrylic-emulsion solids.
- Cured Concrete Top Treatment — Apply in diluted form at 3-5% solids for stain resistance and release.
Dilution
Add water or water-miscible solvents to concentrated GSRC 220 under agitation.
Surfactants
Surfactants may be added, although the source states they are normally not required.
Defoamers
Defoamers may be used if the complete coating or construction system requires foam control.
Nonpolar Incompatibility
Not compatible with xylene, mineral spirits or other nonpolar hydrocarbons.
Cure Validation
Allow full cure before evaluating stains, water/oil contact angles and cleaning durability.
Freeze-Thaw Handling
Limited freezing and thawing can be tolerated, but repeated cycles should be avoided.
