Neill's Materials - Key-22 Silicone Rubber
With casting prosthetic appliances from flat moulds becoming more and more popular Neill’s Materials set out to find a great performing silicone that would be perfect for this and other applications. Introducing Key-22.
The main features of Key-22 are;
- Great price
- High tear strength
- Low viscosity so it can be poured without needing vacuum de gassing equipment.
- Medium fast cure of under 2 hrs, plenty of time to pour and for bubbles to escape but you’re not waiting all day to get on with your project.
Key-22 is not sensitive to inhibition, all addition cure silicones can suffer inhibition but some are more sensitive than others. Key-22 is one of the more robust silicones and can be cast off products such as Chavant NSP and fresh polyester resin moulds that some other silicones may have inhibition issues with is also terrific for matrix moulds and for brush up moulds.
