What?s difference with normal clear and high transparent?1.The yellowing of normal clear resin has always been a shortcoming criticized by 3D printing users, and this transparent resin will not become yellow.2.After the second treatment, this transparent resin will have transparency similar to glass and acrylic sheet. This is a real transparent resin.Special Using Note: 1. This resin can only be used for models with high light intensity which UV light more than 3500uw/cm². The resin viscosity is higher than normal resin, it is difficult to cure by low-intensity LCD printer (RGB screen printer). 2. The printing time of this resin on the normal layer (monochrome screen) is 6s. 3. The poured resin should be used up as much as possible at one time. This resin is prone to change during the curing process, and the remaining resin in the tank is prone to yellowing during the second use. 4. The storage must be completely protected from light. 5. The surface of the cured product is prone to blurring when exposed to alcohol (but better than the previous rigid and transparent resin), and the subsequent polishing oil can be completely transparent.
