Review: Does the job! - It was my first time making a mould and it turned out really well. The cure time is supposed to be 3hrs at the right temperature, but I left it way over 12hrs as it felt tacky. Would highly recommend just a shame on the price, bit expensive. Ordered this item twice and each arrived within a day or two.
Review: very easy to use - i wanted to make a mold of a large ostrich sized egg for resin work , mixed up easily , no visable bubbles , good mold and quite stiff when set up so it should last a while

## Features

- 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.

### ⭐⭐⭐⭐ Good product but arrived with damaged packaging and a leaked product.
*by C***N on 5 June 2022*

Bit disappointed with the packaging, could be more secure to prevent leaks. However it did arrive very quickly and I look forward to trying it out. I will definitely update my review when I've tried it but from what my friends have said and shown me, it's very good stuff, well worth the money with great results and very easy to use.
