Users Instructions of pourable silicon rubber for casting concrete & stone & cement
Pourable silicon rubber for casting concrete & stone & cement are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability.When mixed with 4%~5% curing agent, they can still be operable within 35 minutes, but pourable silicon rubber will be formed after 3-5 hours.
Pourable silicon rubber for casting concrete & stone & cement is a white or red flowable liquid with a hardness of 28±2° when it gets cured. For molds making of large-sized products, multiple-piece molding methods is required.
Mixing Ratio for pourable silicon rubber for casting concrete & stone & cement
1,Added with 2% of curing agent, silicon can still flow within 2 hours, mold can be released in 7-8 hours.
2,Added with 3% of curing agent, silicon can still flow within 1 hours, mold can be released in 6-7 hours.
3,Added with 4% of curing agent, silicon can still flow within 40-50 minutes, mold can be released in 5-6 hours.
4,Added with 5% of curing agent, silicon can still flow wtithin 30-40 minutes, mold can be released in 3-5 hours.
