Q1: What is the primary application area for SETAL 360?
A: SETAL 360 is a medium-oil, cobalt-free alkyd resin specifically designed for high-performance air-drying decorative and protective coatings, including interior and exterior architectural paints, wood finishes, and general industrial maintenance coatings where good gloss retention, flow, and through-dry are required.
Q2: Is SETAL 360 compatible with common co-resins and additives used in alkyd formulations?
A: Yes, SETAL 360 exhibits excellent compatibility with standard alkyd modifiers such as melamine-formaldehyde resins, urea-formaldehyde resins, and acrylic co-polymers. It also works well with conventional driers (e.g., calcium, zirconium, and manganese-based), rheology modifiers, and defoamers commonly employed in solventborne alkyd systems.
Q3: How does SETAL 360 differ from traditional cobalt-catalyzed alkyds in terms of drying behavior?
A: As a cobalt-free system, SETAL 360 relies on alternative drier combinations to achieve balanced surface dry and through-dry. It offers reduced risk of wrinkling and improved film uniformity compared to cobalt-heavy formulations, while maintaining robust oxidative crosslinking performance under ambient conditions.
Q4: Can SETAL 360 be used in low-VOC formulations?
A: Yes — SETAL 360 is formulated to support VOC-compliant systems. Its solubility profile allows effective use with higher-boiling, lower-volatility solvents (e.g., aromatic-free mineral spirits or reactive diluents), enabling formulators to meet regional VOC limits without compromising film formation or drying efficiency.
