- Applications
- Highly reactive hydroxy acrylic resin intended for crosslinking with isocyanate resins. It has a broad compatibility with similar acrylic resins.
- Coatings based on Domacryl 5109 85 Bac/Ac have good balance between hardness and flexibility, with excellent mechanical properties and superior outdoor durability.
- Used for room temperature drying or forced drying two-pack systems for automotive refinishing and general metal coatings (clear and pigmented top coats).
- Supply form in butyl acetate is suitable for aromatic-free systems and gives ultra high solid systems at spraying viscosity (VOC ≤ 300 g/l).
- Suitable for DTM (direct-to-metal) application.
- Crosslinking with aliphatic isocyanates is recommended for the formulation of non-yellowing finishing.
- Physical drying can be accelerated with the addition of CAB resins.

Technical Details & Test Data
- Solubility
- Limited solubility in aromatic solvent 100 and aromatic solvent 150.
- Soluble in xylene, toluene, acetone, ethyl acetate, n-Butyl acetate, methoxy propyl acetate and methyl isobutyl ketone.
- Remarks
- Coatings based on Domacryl 5109 85 Bac/Ac requires at least 5-times higher amount of curing catalyst.
- Compatibility
- Compatible with isocyanate resins: HDI-isocyanurate, HDI-biuret, and other binders: Vinyl VAGH, nitrocellulose (ester soluble), majority of other Domacryl hydroxy resins.
Storage & Handling
- Storage
- The resin should be stored indoors in its original, unopened and undamaged container in a dry place at storage temperatures below 35 °C, for up to 12 months. Exposure to direct sunlight should be avoided.
