Short Oil Fast Drying (16/50) (SDA)
Short Oil Fast Drying (16/50) Stand & Detail Alkyd (SDA) is a specially formulated alkyd resin designed for rapid drying and excellent film formation in coatings. It contains approximately 16% oil length, offering a balance between hardness and flexibility, and 50% solids content, which aids in build and coverage. This resin is widely used in industrial and decorative paints where quick drying and good adhesion are critical. Its fast curing properties make it ideal for applications requiring reduced downtime and enhanced productivity.
 Primary Uses
Industrial and Decorative Coatings
- Used in fast-drying enamels, primers, and topcoats for metal and wood surfaces.
- Provides good adhesion and hardness with moderate flexibility, suitable for furniture and machinery coatings.
- Employed in automotive refinishing paints for quick recoat and durable finish.
Wood Coatings
- Used in wood varnishes and lacquers where rapid drying and good clarity are needed.
- Enhances surface hardness and resistance to abrasion and chemicals.
Printing Inks
- Utilized in alkyd-based inks requiring fast drying on various substrates.
Secondary Uses
Adhesives
- Incorporated in solvent-based adhesive formulations for improved tack and film formation.
Art Supplies
- Used in artist paints and protective coatings due to quick drying and durable finish.
Marine Coatings
- Applied in specialized fast-drying coatings for maintenance and repair on boats and ships.
