When we are doing production, if we are new to liquid silica gel and are not familiar with the performance parameters of silica gel, when choosing the hardness, it is often either too soft or too hard, which does not meet the requirements. Then we will tell you now, if Products made with our liquid silicone are too soft or too hard. How should I adjust them?
If the liquid silicone is too hard, how to soften it: You can add an appropriate amount of silicone oil into the silicone to soften the silicone. The proportion of addition is between 5% and 10%. Do not add more. If too much silicone oil is added, it will affect the pulling force of the silicone! Or you can use silica gel to adjust the silica gel, which means mixing low-hardness silica gel into high-hardness silica gel, thus neutralizing the hardness of the silica gel! This method has no impact on the performance of the silicone.
How to adjust the hardness of liquid silicone from soft to soft: You can add an appropriate amount of hardener to the silica gel. The addition ratio of the hardener is about 5%. Add it to the B component of the silica gel and stir evenly.
