Q1: What is the primary application field for SETAL FL70/70?
A: SETAL FL70/70 is a fast-drying, medium-oil alkyd resin specifically designed for high-performance air-drying decorative and industrial maintenance coatings, including wood finishes, metal primers, and general-purpose enamels where good gloss retention and through-dry are required.
Q2: How does SETAL FL70/70 differ from conventional long-oil alkyds?
A: Unlike traditional long-oil alkyds, SETAL FL70/70 features a balanced oil length and optimized fatty acid composition that delivers faster surface dry and improved hardness development while maintaining flexibility and adhesion—making it suitable for applications requiring shorter handling times without sacrificing film integrity.
Q3: Can SETAL FL70/70 be used in solvent-borne and water-reducible systems?
A: Yes, SETAL FL70/70 is formulated for compatibility with common aromatic and aliphatic hydrocarbon solvents and can be successfully incorporated into solvent-borne systems. It may also be adapted for water-reducible formulations using appropriate co-solvents and neutralization strategies, though compatibility testing is recommended for each specific formulation.
Q4: What types of crosslinkers or curing agents are compatible with this resin?
A: SETAL FL70/70 is typically used in air-drying mode via autoxidation and does not require external crosslinkers. However, it can be modified or blended with amino resins (e.g., melamine-formaldehyde) for stoving applications, or combined with isocyanate-functional additives to enhance performance in dual-cure systems—subject to compatibility and stability evaluation.
