Q1: What types of waterborne resins is KY-2794 compatible with?
A: KY-2794 is specifically formulated for use with waterborne polyurethane dispersions (PUDs), acrylic emulsions, and hybrid acrylic-PUD systems. It demonstrates good compatibility and reactivity across a broad pH range and provides efficient crosslinking without significant viscosity instability or coagulation.
Q2: How does KY-2794 affect film formation and final coating properties?
A: KY-2794 promotes rapid ambient-temperature crosslinking, enhancing hardness, chemical resistance, and scrub resistance in the cured film. It supports excellent clarity and low haze in clear coatings and contributes to improved mar resistance and reduced blocking tendency without compromising flexibility.
Q3: Is KY-2794 suitable for low-VOC or zero-VOC formulations?
A: Yes — KY-2794 is a water-based, non-solvent curing agent with negligible VOC content. It aligns well with regulatory expectations for low-VOC industrial and architectural coatings, and does not introduce hazardous air pollutants (HAPs) or ozone-depleting substances.
Q4: What is the recommended addition method and storage guidance?
A: KY-2794 should be added to the aqueous phase under gentle agitation, preferably after resin dispersion and before neutralization or thickener addition. Store in original sealed containers at 5–30°C, away from freezing and prolonged exposure to high humidity or direct sunlight. Shelf life is typically 12 months under proper storage conditions.
