Overview
ALITA 905 Brominated Vinyl Ester Resin
Category：Anti-corrosion ResinCode：ALITA 905
Features
ALITA 905 is a brominated Bisphenol-A vinyl ester resin, offering exceptional corrosion resistance and inherent flame retardancy.
- Performance: Built-in fire retardancy through halogen atoms in the resin backbone. Ideal for applications requiring both chemical resistance and flame retardant properties.
- Physical Characteristics: Excellent mechanical strength, long-term acid/alkali resistance, stable processing, and fast curing speed.
- Process Versatility: Compatible with hand lay-up, spray-up, and filament winding processes.

Storage & Handling
- Safety Protection: This resin contains ingredients that may be harmful if mishandled. Avoid contact with skin and eyes; appropriate protective equipment and clothing must be worn during operation.
- Storage Temperature: It is strongly recommended to store all materials in a constant temperature environment below 25℃. Avoid exposure to heat sources such as direct sunlight or steam pipes.
- Environmental Requirements: To prevent moisture contamination, do not store outdoors. Keep containers tightly sealed to prevent moisture absorption and monomer loss.
- Management: Follow the "First-In, First-Out" principle for stock rotation.
