Silicone sealant has good fluidity, simple operation and convenience, can be perfusion, injection and other molding applications, after curing, has excellent electrical, protection, physical, weather resistance and other performance characteristics. In terms of curing mode, there are two types of silicone potting adhesive, additive and condensation, so what are the differences in application?

1.curing depth

After add molding pouring sealant of two-component mixed evenly, glue, curing process as a whole is consistent, that is to say, how thick is glue, how thick is the whole curing, and because condensation type pouring sealant curing process need to participate in the moisture in the air for reactions, curing from surface to inner, and moisture curing depth and time, so in the application, Condensation type potting adhesive is generally not suitable for deep or thick products.

2.heating application

Improve the silicone potting glue curing speed, can improve the efficiency of production, so a lot of users increase the baking process, greatly accelerate the time of the next procedure, but this process is only suitable for shaping the use of silicone potting glue, condensation type pouring sealant cure requires two key conditions, moisture and catalyst, has no obvious relation with temperature.

3.bonding performance

Silicone potting adhesive in the application process, the need to have a certain bonding performance, the priority is to choose the condensation type of silicone potting adhesive, and most materials have good bonding performance, there will be no edge adhesion phenomenon, add formed silicone is slightly worse than.
