ALITA 107TP Flame-Retardant Polyester Resin (Pre-promoted & Thixotropic)

ALITA 107TP is a general-purpose, reactive flame-retardant unsaturated polyester resin. This product is specially formulated to be Pre-promoted, Thixotropic, and Wax-containing to enhance processing efficiency and final product quality. Products made with this resin (formulated with T-paste) exhibit excellent flame retardancy and robust mechanical properties.

• Excellent Wetting: Good fiber wetting properties ensure complete impregnation and minimize air pockets.
• Non-Sag: The thixotropic nature prevents sagging on vertical or inclined mold surfaces.
• Tack-Free Curing: The wax content ensures a clean, tack-free surface after curing.
• Flame Retardant: FRP products formulated with T-paste exhibit high fire safety (Oxygen Index up to 32%).

Widely used for manufacturing FRP products with strict flame retardant requirements, including:

• Marine vessels, yachts, and harbor structures.
• Industrial cooling tower fan cylinders, casings, and drift eliminators.
• Automotive body panels, truck fairings, and cabin enclosures.
• FRP cable boxes, electrical enclosures, and subway structural panels.

Note: Gel time tested at 25°C with: Resin 100g, Accelerator E1: 4ml, Curing Agent H-Paste: 4g.

1. Cured Base Casting Properties (Typical):

2. Cured FRP Laminate Typical Properties (with T-paste):

• Accelerator Choice: Special promoters like E4 are recommended. Avoid using high-efficiency colorless amine accelerators to prevent surface tackiness.
• Gel Time Adjustment: If high ambient temperatures cause premature gelation, do not reduce the curing agent below the minimum safety dosage; use a gel retarder instead.
• Tackiness Control: Under high humidity or temperature, if surface tackiness is observed, a small amount of additional wax solution can be incorporated.
• Curing Conditions: Casting preparation according to GB/T 8237-2005. Post-cure program: Room Temp × 24h + 60°C × 3h + 80°C × 2h. FRP post-cure: Room Temp × 24h + 60°C × 3h + 110°C × 2h (OI specimen thickness: 3mm).
• Storage: Store below 25°C in a cool, ventilated area, away from ignition sources. Shelf life is 3 months.
