The causes of the problems may be: the error of measuring instruments or human factors lead to the wrong glue ratio; The product exceeds the storage period or is close to the storage period, resulting in failure and reduced efficiency; During storage, the catalyst in the product fails or the efficiency decreases due to improper storage; When in use, there are factors poisoning the catalyst in the environment, such as organic compounds containing phosphorus, sulfur and nitrogen, or products such as polyurethane, epoxy resin, unsaturated polyester and condensed room temperature vulcanized silicone rubber are used together with addition silicone rubber; Insufficient curing temperature or time will lead to incomplete curing.
Solution: Measuring instruments must be calibrated regularly; When gluing in two groups, double system is adopted; Ensure the storage conditions required by the manufacturer, pay attention to the shelf life, follow the principle of "first in, first out" when using, and ensure that it is used up in the shortest period of validity. The workplace is far away from other potentially harmful organic compounds, and it is forbidden to use rubber compounds immediately after smoking. Zhao Shun Science and Technology's silicone sealant is good.
