Sylmasta Silicone Moulding Rubbers
Sylmasta Silicone Moulding Rubber is professional quality silicone rubber used for making high-quality, reusable moulds. Two hardnesses are available alongside mould release agent, which is used to prevent rubber sticking to itself during the making of split moulds.
Softest grade of Sylmasta Moulding Rubber with high flexibility for creating moulds with deep undercuts. Has a pot life of 45 – 120 minutes and a de-mould time of 10 hours
Stiffer grade of Sylmasta Moulding Rubber, offering greater dimensional stability and tear strength. Has a pot life of 45 – 120 minutes and a de-mould time of 8 hours
Mould Release Agent is used when making a split mould to prevent the two parts from sticking to each other. Comes with a brush cap for easy application
Polycast Casting Resins
Polycast Casting Resins are non-shrink polyurethane resins for creating high-quality resin casts. A range of viscosities and cure speeds are available. Polycast Resins set to beige as standard. Should a specific coloured casting resin be required, then we have the capability to custom-make a resin to any RAL or PANTONE colour.
G27 White has been specifically designed for those seeking a white curing resin. Also available is Sylmasta CPU31 ClearCast, an optically clear, non-yellowing polyurethane resin resistant to UV for producing water-clear casts.
G26 Polyurethane Casting Resin
Medium viscosity polyurethane resin for casting larger parts of 0.5mm and upwards. Has a pot life of 3 – 4 minutes and a de-mould time of 30 minutes to 10mm thick
G27 Polyurethane Casting Resin
Low viscosity polyurethane resin for casting parts as small as 0.5mm thick. Has a pot life of 150 seconds and a de-mould time of 25 minutes to 10mm thick
G27 White Polyurethane Casting Resin
Low viscosity polyurethane resin for casting parts as small as 0.5mm thick which sets white rather than the beige colour of standard G27
G27LV Polyurethane Casting Resin
Very low viscosity polyurethane resin which is extra searching for picking out the finest details. Has a pot life of 2 minutes and a de-mould time of 15 minutes to 10mm thick
Optically clear, non-yellowing polyurethane resin which is resistant to UV. It makes water clear casts and is used for embedding and encapsulating objects.

To see how easy it is to start casting and mould making using a Sylmasta Casting Kit, then please see our Showcase article on How to make and use a two-part silicone mould for resin casting, which includes an instructional video.
As well as model makers, kit builders and industrial users, the Casting Kit is also used by those in the resin jewellery industry for producing one-of-a-kind pieces. You can see examples of jewellery made using Sylmasta casting and mould making products on the website of a resident resin artist, The Pea Hive.
