| Features and main uses： | |||
| TC-141 is a kind of low viscosity, non pre promoted unsaturated polyester resin specially designed for transparent water white casting crafts. It has the characteristics of moderate exothermic and rapid curing. It can be used with accelerator RP-51 (or RP-126) to obtain the transparency similar to glass. | |||

| Matters needing attention: | |||
| 1. Different production processes and formulations have an impact on the color and transparency of the resin, so before using a large number of resins, several samples should be made to determine the color and transparency of the resin. | |||
| 2. The product should be stored in a cool place below 25 ℃ to avoid fire and keep away from heat and radiation sources. The shelf life of products stored below 25 ℃ is 3 months. | |||
