A pourable addition curing, two-component silicone that vulcanizes at room temperature

An Ideal Choice for Creating Jewelry Molds

• Excellent for accurate reproduction of very small details​

Extremely Durable Over Time

• Cured silicone rubber molds commonly retain their shape and detail for up to 20 years

Excellent Stability Over Time

• Extremely stable and not affected by humidity, light, or temperature after vulcanization 

• Maintains its dimensional stability over the life of the mold

Zero Shrinkage

• Demonstrates virtually zero shrinkage, so need to compensate

Mixing Ease

• Mixed in a 1:1 ratio, eliminating the need for expensive mixing equipment

• Not as sensitive to errors in mixing proportion as non-silicone room temperature cured materials

Increased Production Speed

• Sets in less than 4 hours, allowing user to make a mold and inject patterns the same day
