Product Properties
Bailiangcai P 61TV-956L is a pre-promoted, thixotropic orthophthalic unsaturated polyester resin characterized by low viscosity and high reactivity, making it suitable for hand lay-up and spray-up processes.The resin contains a low-styrene evaporant (LSE) and a curing-process color-change indicator. It exhibits good wetting properties with glass fiber and excellent workability.
P 61TV-956L offers superior mechanical properties and good water resistance.
Main Applications
Bailiangcai P 61TV-956L is widely used in hand-layup and spray-up processes. Bailiangcai P 61TV-956L has low viscosity and excellent wetting properties for glass fiber.P 61TV-956L has been certified by the China Classification Society (CCS). It offers good water resistance and low shrinkage, and is primarily used in the shipbuilding industry and for the manufacture of engine cowling.

Instructions for Use and Precautions
- MEKP may be used as the curing agent at a concentration of 1.0–2.5%. Ensure the curing agent is within its shelf life.
- Palatal P 61TV-956L resin already contains an accelerator. After prolonged storage, the thixotropic agent in the resin may gradually settle; ensure it is evenly dispersed before use by inverting and rolling the drum several times or stirring the contents of the container appropriately.
- To optimize the performance of the finished product, post-cure for several hours at 80°C.
