ActivePlastics—Unsaturated polyester resins—Part 7: Measurement of gel time at ambient temperature
塑料 不饱和聚酯树脂（UP-R） 第7部分: 室温条件下凝胶时间的测定
Application Summary AI generated
This standard specifies a method for measuring the gel time of unsaturated polyester resins at ambient temperature, which is the time required for the resin to transition from a liquid to a gel state under specified conditions. It is applied in the plastics and composites industry for quality control and formulation development, particularly in processes like hand lay-up, spray-up, and casting where the resin's curing behavior at room temperature is critical.
