- Appliations
- Hydroxy acrylic resin with very long pot-life and super-fast hardness development.
- Designed to be used in TOP PERFORMANCE 2K PUR air or forced drying system in automotive, ACE and general metal top coats.
- Supply form in butyl acetate is suitable for aromatic-free systems and gives high solids system at spraying viscosity (VOC ≤ 420 g/l).
- Coatings based on Domacryl 5270 75 BAc have very good balance between hardness and flexibility, with excellent mechanical properties and superior outdoor durability.
- Crosslinking with aliphatic isocyanates is recommended for the formulation of non-yellowing finishing.
Properties
- Soluble in
- Acetone, Toluene, Xylene, Ethyl Acetate, Methoxy propyl acetate, Methyl isobutyl ketone, n-butyl acetate, Aromatic Solvent 100, Aromatic Solvent 150
