About this item
  • FEATURES: R PRO 20 is a 1:1 addition-cure liquid silicone rubber with high tear resistance. Suitable for modeling and mold making, this versatile silicone is ideal for creating medium-hardness molds (20 Shore) that reproduce even the smallest details and undercuts.
  • HIGH PERFORMANCE: R PRO 20 silicone for molds faithfully reproduces fine details, allows up to 20% more castings compared to other silicones, and molds have no linear shrinkage. It is a very fluid rubber that ensures easy mixing and does not require vacuum degassing.
  • HARDNESS: Once cured, this silicone produces soft molds (20 Shore A hardness) that are highly elastic and resistant to tearing. Working time: 45 minutes – Curing time: 3 hours.
  • MOLD PERFORMANCE: The physical lifespan of the mold depends on its use (casting materials, frequency, etc.). Casting abrasive materials such as concrete can quickly wear out mold details, while non-abrasive materials (such as wax) preserve them.
  • NOTE: Sulfur-based plasticine is not compatible and may inhibit the curing of R PRO silicones.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
