Overview
ALITA 583 Polyester Putty Resin (High-Performance Body Filler Resin)
Category：Putty ResinCode：ALITA 583
Applications
ALITA 583 is a DCPD-type unsaturated polyester resin specifically designed for manufacturing high-performance automotive repair putties (body fillers).
- System Characteristics: Utilizes an amine-promoted pre-accelerated system; rapid and efficient curing is achieved when used with 50% BPO paste curing agent.
- Application Advantages: Features exceptional sandability, easy spreading, and smooth leveling. It offers fast drying speeds and extremely low shrinkage after molding.
- Adhesion & Compatibility: Exhibits ultra-strong adhesion to galvanized and aluminum sheet surfaces. It also possesses good impact resistance, flexibility, and excellent anti-yellowing performance.
- Application Areas:
- Filling and leveling for cars, trucks, agricultural vehicles, and machine tool surfaces.
- Large-area polyester putty applications and vehicle body repairs.

Features
1. Fast Drying & Easy Sanding: Shortens waiting time before sanding, significantly boosting repair efficiency.
2. Excellent Air-Drying: The surface is dry and non-tacky, facilitating subsequent sanding steps.
3. High Fillability: Can be used with large amounts of inorganic fillers to create low-cost, high-performance putty.
4. Storage Stability: Exhibits excellent long-term storage stability; resistant to layering or deterioration.
Storage & Handling
- Safety Protection: Contains active monomers; avoid skin and eye contact. Always wear protective clothing, gloves, and personal protective equipment.
- Environmental Control: Strongly recommended to store below 25℃ (77℉). Strictly avoid direct sunlight and placement near steam pipes or any heat sources.
- Management: Outdoor storage is strictly prohibited to prevent moisture pollution. Keep sealed to minimize monomer (styrene) evaporation and loss.
