Q1: What is the primary function of SETALUX 10-1387 in coating formulations?
A: SETALUX 10-1387 is a hydroxyl-functional acrylic resin designed to serve as a reactive binder in two-component polyurethane (2K PU) and polyester-based crosslinking systems. It contributes to film formation, enhances hardness and chemical resistance, and supports excellent gloss retention and weatherability in high-performance industrial and automotive topcoats.
Q2: Is SETALUX 10-1387 compatible with common isocyanate crosslinkers?
A: Yes — it is specifically formulated for compatibility with aliphatic isocyanate crosslinkers such as HDI trimer and biuret types. Its hydroxyl functionality ensures efficient reaction kinetics and robust network development under ambient or forced-dry conditions, supporting good pot life and film integrity.
Q3: How does SETALUX 10-1387 perform in terms of UV stability and outdoor durability?
A: As a purely acrylic, aliphatic hydroxyl resin, SETALUX 10-1387 delivers inherently high UV stability and resistance to chalking or yellowing. When properly formulated and cured, it supports long-term gloss retention and color stability in exterior applications such as automotive clearcoats and premium industrial finishes.
Q4: Can SETALUX 10-1387 be used in low-VOC or high-solids coating systems?
A: Yes — its molecular design enables formulation flexibility in medium-to-high solids solventborne systems. It can be adapted for low-VOC compliance when combined with appropriate solvents and co-resins, though final VOC content depends on the full formulation matrix and regulatory definitions applicable to the target market.
