ALITA 2003 Isophthalic Unsaturated Polyester Resin

ALITA 2003 is a high-performance, isophthalic-type unsaturated polyester resin. It features excellent wetting and impregnation capability for glass fibers alongside outstanding application and processing behavior.

• Mechanical Toughness: Cured casting parts exhibit robust toughness, robust impact resistance, and a high Heat Deflection Temperature (HDT 100°C).
• Corrosion Resistance: Delivers reliable protection and chemical resistance against a broad spectrum of aggressive media.
• Recommended Processes: Highly optimized for fabricating fiber-reinforced plastic (FRP) products with demanding temperature and corrosion-resistance requirements via hand lay-up, filament winding, or pultrusion molding processes.

• Accelerator Selection: Do not apply highly efficient colorless accelerators, as they cause incomplete cross-linking leaving a sticky surface. We strongly recommend E4 or alternative professional-grade FRP accelerators.
• Gel Time Management: Under high temperatures, never reduce the curing agent dosing ratio below the recommended threshold. Add trace quantities of Gel Time Retarder / Inhibitor instead to control the reaction pathway.
• Air Inhibition: Under high humidity, oxygen/air inhibition may cause surface tack. An optimized dosage of paraffin wax solution can be incorporated to prevent this.

• Logistics Safety: Transportation must align with National Regulations Governing the Logistics and Safe Transport of Dangerous Chemicals.
• Storage Conditions: Stored in tightly sealed containers indoors inside a cool, dry, well-ventilated warehouse below 25°C. Keep away from sparks, open flames, solar radiation, or steam pipes.
• Guaranteed Shelf Life: Guaranteed for 3 months from ex-factory date under compliant storage. Read the safety protocols in the official Safety Data Sheet (SDS) before use.
