Silicone Retarder

Silicone Retarder is a special chemical additive, mainly used to regulate the curing time of silicone. During the silicone printing process, It can extend the transition time of silicone from liquid to solid, allowing the operator to have more time for subsequent operations, such as adjusting the position, repairing defects, and so on. This additive is widely used in a variety of silicone printing scenarios, including but not limited to electronic products, medical devices, automotive parts and other fields.

Silicone Retarder mainly realizes the delay effect by changing the cross-linking reaction speed between silicone molecules. Specifically, the chemical components in the time-delay agent can form a temporary barrier layer between the silicone molecules to reduce the cross-linking reaction rate, thereby extending the curing time of the silica gel. In addition, It needs to be mixed well with the silicone to ensure that its effect can be evenly distributed in the entire silicone system.

Use process：

A.Prepare the required silicone, silicone retarder, mixing tools, etc., and make sure the working environment is clean and tidy.

B.According to a certain proportion of them mixed together, with mixing tools to mix well, until the two are completely integrated.

C.Apply the mixed siliconel to the required parts by screen printing to ensure that the silicone is evenly distributed and free of air bubbles.

D.Before the silicone starts to cure, adjust the proportion of delay agent according to the actual need to extend the curing time of the silicone.

E.During the curing time of the silicone, adjust and repair the silicone as needed.

F.After the silicone is fully cured, carry out the necessary post-processing, such as cleaning and testing.

Tips：

A.Adjust the ratio according to actual needs to achieve the desired time-delay effect. Too much may cause the silicone curing time is too long, affecting the production efficiency; while too little  may not be able to achieve the desired effect.

B.Ensure they are mixed well and evenly to avoid the situation of too much or too little time-delay agent locally.

C.Pay attention to the temperature and humidity of the working environment, too high or too low temperature may affect the curing speed of the silicone.

D.Before the silicone starts to cure, adjust the proportion of it in time according to the actual situation to ensure that the silicone has enough curing time.

E.When using it, follow the safety operation procedures and avoid direct contact with skin and eyes. At the same time, do a good job of waste disposal to avoid pollution of the environment.
