Liquid silicone caused by uneven mixture of reasons: uneven AB a two-component mixed lead to impurities. Solution: adjust the agitator rotational speed and back pressure, direction, time can be extended when necessary. Liquid silicone mold problem caused by the reasons: the silicone mold residues. Solution: thoroughly clean silicone mold residues. The operator factors: operator did not wear Labour protection glove, error, etc. Solution: change regularly gloves, the standard operation procedure silicone paste incompatible causes of: silicone paste mixing inequalities, Or paste dispersed, precipitation) , because of all kinds of silica gel composition is different, the paste will have difference, it is recommended to use rubber manufacturers matching color paste.
