The diluents commonly used in silicone heat transfer hot melt glue include organic solvents such as cyclohexanone and xylene. These diluents can effectively reduce the viscosity of hot melt glue during the preparation of silicone thermal transfer and hot melt adhesives, making it easier to process and apply.
However, it should be noted that different diluents may have different effects on the performance of silicone. For example, the type and amount of diluent may affect the key properties of silicone such as curing speed, hardness, and heat resistance. Therefore, when selecting diluents, it is necessary to make comprehensive considerations based on the specific application requirements and the performance requirements of silicone.
In addition, safety and environmental protection issues should also be paid attention to when using diluents. Organic solvents such as cyclohexanone and xylene have certain volatility and toxicity. When using them, it is necessary to ensure good ventilation in the workplace and wear appropriate protective equipment. At the same time, these solvents also need to be properly stored and handled to avoid harm to the environment and human health.
In summary, the selection of diluents for silicone thermal transfer hot melt adhesives needs to take into account a variety of factors, including application requirements, silicone performance, safety, and environmental protection. In practical applications, it is recommended to conduct experiments and optimization according to specific circumstances to determine the best type and amount of diluent.
