Users Instructions of mould making material ---- liquid silicone rubber
Mould making material ---- liquid silicone rubber (silicone) and silicone are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability.When mixed 5% curing agent, they can still be operable within 35 minutes, but it will be formed after 3-5 hours.With a favorable resistance to deformation, high temperature, acid & alkali, and expansion, silicone flexible molds are used for mold duplication and delicate mold making for poly crafts, resin crafts, lighting and candle crafts, etc.
This product is a white or red flowable liquid with a hardness of 27—28A° when it gets cured. For molds making of large-sized products, multiple-piece molding methods is required. Meanwhile you will need silicone rubber with a higher hardness. Conversely, soft silicone is indispensable for molds with complicated patterns and delicate details. The amount of curing agent admixture depends on your requirements. Pls add more for a speedy drying process and a fast releasing and less on the other hand.
(Notes:Normally we do not recommend you to add any silicone oil. For special soft mold or molds with complex pattern or fine details, 5%~10% silicon oil can be added to condition the flexibility of the mold for convenience of release)
Mixing Ratio for mould making material ---- liquid silicone rubber (Under room-temperature-25 °C )
1,Added with 2% of curing agent, liquid silicone rubber can still flow within 2 hours, mold can be released in 7-8 hours.
2,Added with 3% of curing agent, liquid silicone rubber can still flow within 1 hours, mold can be released in 6-7 hours.
3,Added with 4% of curing agent, liquid silicone rubber can still flow within 40-50 minutes, mold can be released in 5-6 hours.
4,Added with 5% of curing agent, liquid silicone rubber can still flow wtithin 30-40 minutes, mold can be released in 3-5 hours.
For best results, allow the mold to air cure an additional 24 hours before using it in production.
Shelf Life of mould making material ---- liquid silicone rubber
Twelve(12) months from date of shipment when the liquid silicone rubber stored under 250C in the original sealed packages.
