Liquid silicone conventional said on market is divided into two kinds, one kind is condensation silicone, condensation silicone into the silicone and curing agent, one is forming silica gel, and forming silica gel is divided into A and B A two-component, condensation type silicone is moisture curing at room temperature, so it to the temperature and the humidity of the air will have large demand, choose good new condensation silicone materials are of good quality, stable supply, According to the ratio of 100:2-3 curing agent, fully stir evenly before use.It normally takes 5 to 8 hours to set at 25° at room temperature.

    Condensation silicone cure time related to customers operating habits, brush mould technology and mould technology of curing time is different, the condensation mould to make the mold by using silica gel liquid silicone irrigation mode, the proportion of curing agent and 2% commonly, room temperature is 25 degrees of operation, the operating time for 30 to 40 minutes, completely cure need three to five hours.With the brush die technique, the curing agent can be added up to 3%, and the operation time is 10-15 minutes at 25 ° C, and the complete cure takes 2 to 3 hours.

    Condensation type silicone curing agent time is also affected by the weather temperature climate, the summer temperature is higher, the liquid silicone curing agent time is accelerated, the winter temperature is lower, the liquid silicone curing time is slowed down, so the condensation type mold silicone curing agent in summer and winter is not the same, can be adjusted according to the change of climate.

    The curing time of condensed industrial grade mould silicone liquid silicone and added environmental grade mould silicone liquid silicone can also be adjusted to be different.Do mold use of silica gel recommended to place 24 hours after the use of better effect, such as do not understand the new best to contact the detailed technical support condensation silica gel solidification time.Due to operating environment factors will affect the curing time.In the same way that forming silica gel is divided into A and B of two-component silicone, group A is platinum vulcanizing machine, B component as the curing agent, stir in forming silica gel ratio is 1:1, such as operating time for 30 minutes, under the condition of room temperature is 25 degrees Celsius, curing time is 3 to 4 hours, and the types and forming silica gel can be heat curing, such as heat up to 120 ° C, It should cure completely in about 30 minutes.Using 25 degrees Celsius as a reference, the operating time and curing time are halved when the temperature rises by 5 degrees Celsius, and doubled when the temperature decreases by 5 degrees Celsius.Silica gel operation time and room temperature curing time can be adjusted according to the requirements, the heating temperature and time can be modified according to the production of the product, for further information, please consult Zinca.
