Precautions during using
When synthesizing the resin mixture, the H/OH conversion rate is very high. Long term exposure to the air can absorb a large amount of carbon dioxide, thereby affecting the performance and usage of the product. Therefore, once unpacked, it should be used as soon as possible, and the unused parts must be carefully sealed; This product should not be directly exposed to sunlight or direct sunlight; There is no need to inject water into the exchange during use to avoid secondary stratification.
