Q1: What is the primary function of SETALUX 91772 SS-60 in coating formulations?
A: SETALUX 91772 SS-60 serves as a hydroxyl-functional acrylic resin designed to act as a reactive binder in two-component polyurethane and polyester-based systems. It contributes to film formation, crosslink density, and final coating performance—including hardness, flexibility, and chemical resistance—when reacted with suitable isocyanate curing agents.
Q2: Is this resin compatible with common aliphatic isocyanate crosslinkers?
A: Yes, SETALUX 91772 SS-60 is formulated for compatibility with standard aliphatic polyisocyanates such as HDI trimer and biuret derivatives. Its hydroxyl functionality and molecular weight profile support balanced reactivity and pot life in ambient- or forced-dry applications.
Q3: How should SETALUX 91772 SS-60 be stored to maintain stability?
A: Store in tightly sealed original containers in a cool, dry, and well-ventilated area away from direct sunlight and sources of heat or ignition. Avoid prolonged exposure to moisture or freezing temperatures. Under these conditions, shelf life is typically 12 months from date of manufacture.
Q4: Can this resin be used in high-solids or low-VOC coatings?
A: Yes—SETALUX 91772 SS-60 is suitable for formulating medium-to-high solids coatings due to its moderate viscosity and favorable solubility in common oxygenated and aromatic solvents. Its design supports VOC reduction strategies while maintaining workable rheology and film integrity.
