Use Instructions of liquid silicone rubber for mould making
Liquid silicone rubber for mould making (silicone) and silicone are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability.When mixed with 5% curing agent, they can still be operated within 40~70 minutes, but it will be formed after 5 hours.
Liquid silicone rubber for mould making is a white or red flowable liquid with a hardness of 23-25 shore A° when it gets cured. For molds making of large-sized products, multiple-piece molding methods is required.
Mixing Ratio for Silicon Rubber & Curing Agent and the reaction time (Under room-temperature-25 0C)
1,Added with 2% of curing agent, silicone rubber can still flow within 2.5 hours, mold can be released in 8-10 hours.
2,Added with 3% of curing agent, silicone rubber can still flow within 1.1 to 1.2 hours, mold can be released in 6-8 hours.
3,Added with 4% of curing agent, silicone rubber can still flow within 55-60 minutes, mold can be released in 4-6 hours.
4,Added with 5% of curing agent, silicone rubber can still flow wtithin 45-50 minutes, mold can be released in ~4 hours.
Shelf Life of liquid silicone rubber for mould making
Twelve(12) months from date of shipment when stored under 250C in the original sealed packages.
