602U Lighting Tile Unsaturated Polyester Resin

  • Detail
  • Parameters
Features and main purposes:
602U is ortho-type unsaturated polyester resin with medium viscosity and medium reactivity for general purpose use With medium viscosity and high reactivity, it is characterized by good performance in light-resistance, water-resistance and weathering-resistance. After curing, it shows high mechanical properties and hardness, especially applicable for FRP products that have high demand for transparence, light-resistance, water-resistance and weathering-resistance.
