Product Properties
Bailiangcai S 320T-954AT is an additive-type, pre-accelerated, thixotropic, flame-retardant unsaturated polyester resin. Utilizing low-smoke, low-toxicity, and high-flame-retardancy technology, this resin features medium viscosity and moderate reactivity.
Main Applications
Bailiangcai S 320T-954AT features high mechanical strength and excellent processing properties. It is widely used in various self-extinguishing reinforced and non-reinforced products, particularly those with high fire resistance requirements, such as architectural decorative panels,ventilation ducts, transportation vehicles (rail vehicles, boats), and electrical enclosures and components. It is suitable for processes such as hand lay-up, spray-up, and casting.

Instructions for Use and Precautions
- Bailiangcai S 320T-954AT resin contains fillers; stir thoroughly before use.
- Bailiangcai S 320T-954AT resin already contains an accelerator; add a curing agent (such as MEKP) when using it, ensuring the curing agent is within its shelf life. When temperatures are low, an accelerator may be added to adjust reactivity.
- Optimal flame retardancy and mechanical properties are achieved only in fully cured resin-reinforced layers.
