High-performance hindered amine light stabilizer (HALS) specifically engineered for polyurethane (PUR) systems.
Excellent compatibility with aromatic and aliphatic polyurethane coatings, adhesives, and elastomers.
Superior long-term UV resistance and hydrolytic stability, even under humid or outdoor exposure conditions.
Low volatility and minimal migration, ensuring durable stabilization without surface blooming or plate-out.
Non-discoloring performance—maintains clarity and color fidelity in transparent and pigmented PUR formulations.
UV-stable polyurethane clearcoats for automotive and industrial OEM finishing.
Outdoor architectural coatings based on aliphatic PUR resins.
High-performance polyurethane adhesives used in solar panel lamination and façade bonding.
Transparent PUR elastomers for technical seals, gaskets, and optical components requiring weather resistance.
PUR-based sealants and caulks exposed to continuous sunlight and thermal cycling.
