Q1: What is the primary application field for Novalkyd S1157-60XIA?
A: Novalkyd S1157-60XIA is a high-solids, low-VOC alkyd resin specifically developed for premium decorative and protective coatings, including interior and exterior architectural paints, wood finishes, and metal primers where enhanced flow, leveling, and gloss retention are required.
Q2: Is this resin compatible with waterborne systems?
A: Novalkyd S1157-60XIA is an oil-modified alkyd resin designed for solvent-borne formulations. While it may be incorporated into hybrid or pseudo-waterborne systems using co-solvents and surfactants, it is not inherently self-emulsifiable and is not recommended for standard aqueous acrylic or PUD-based systems without thorough compatibility testing.
Q3: How does S1157-60XIA differ from conventional long-oil alkyds?
A: S1157-60XIA features a tailored medium-oil-length structure with optimized fatty acid composition and controlled molecular weight distribution, delivering faster through-dry, improved hardness development, and reduced yellowing tendency compared to traditional long-oil alkyds—especially under ambient curing conditions.
Q4: Can it be used in high-gloss clear coats for wood?
A: Yes—S1157-60XIA is well-suited for high-gloss clear wood finishes due to its excellent clarity, low haze formation, and strong film integrity. It provides balanced flexibility and surface hardness, supporting good sandability and overcoatability in multi-layer systems.
