Medium-oil-length alkyd resin based on phthalic anhydride and soybean oil fatty acids.
Designed for excellent gloss retention and long-term durability in ambient-cure coatings.
Offers balanced drying speed, hardness development, and flexibility for general-purpose applications.
Compatible with common hydrocarbon solvents and conventional alkyd crosslinkers (e.g., melamine-formaldehyde resins).
Delivers good pigment wetting and substrate adhesion on metal and wood substrates.
General-purpose industrial maintenance coatings for steel structures and equipment.
Protective finishes for agricultural and construction machinery.
Decorative and protective enamels for metal furniture and fixtures.
Undercoats and primers requiring moderate corrosion resistance and film integrity.
Refinish coatings for OEM-adjacent metal parts where air-dry performance is essential.

Q1: What is the primary application area for SETAL 1406?
A: SETAL 1406 is a medium-oil-length alkyd resin designed primarily for solvent-based decorative and protective coatings, including interior and exterior architectural paints, wood finishes, and general-purpose industrial maintenance coatings where good gloss retention, drying performance, and substrate adhesion are required.
Q2: Is SETAL 1406 compatible with common co-resins and modifiers?
A: Yes, SETAL 1406 demonstrates good compatibility with melamine-formaldehyde resins, urea-formaldehyde resins, and various acrylic co-polymers. It is also commonly used in blends with polyester and epoxy-modified alkyds to tailor film properties such as hardness, flexibility, and chemical resistance.
Q3: How does SETAL 1406 perform in terms of drying and through-dry characteristics?
A: As a cobalt-free, air-drying alkyd resin, SETAL 1406 offers balanced surface dry and through-dry performance under ambient conditions. Its drying profile supports efficient production workflows in both brush/roller-applied and spray-applied systems, especially when formulated with appropriate driers or reactive diluents.
Q4: Can SETAL 1406 be used in low-VOC formulations?
A: Yes — SETAL 1406 is formulated to enable VOC-compliant systems when used with high-solids solvents or reactive diluents. Its molecular design supports reduced solvent demand compared to traditional long-oil alkyds, making it suitable for formulations targeting regional VOC limits without sacrificing film integrity.
Q5: What are typical storage and handling recommendations?
A: Store SETAL 1406 in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and sources of heat or ignition. Avoid prolonged exposure to moisture or strong oxidizing agents. For optimal performance, use within 12 months of manufacture when stored under recommended conditions.
