As a mould making rubber, RTV27941 offers excellent release-ability with fantastic durability when used with both epoxy and polyurethane resins. These properties are due to its high tear (620 N/mm) and tensile (6.4 MPa) strength, along with elongation of 360%.
Resistance to tear is a very important feature for any moulding rubber, once cured it enables the mould to be stretched and pulled in various directions and still retain its original shape. This is key when removing the cast parts from the mould and will ensure a longer usable life for the mould itself.
RTV27941 is perfect for prototype mould making across a range of industries; favoured in the electronics industry for making home appliance moulds, along with TV’s, mobile phones and copy machines. In the Automotive Industry, RTV27941 is proving popular for creating console box moulds, radiator grills and lamp housings.
With a handy mix ratio of 10:1 and a low working viscosity, RTV27941 is very easy to use. It offers a work life of 90 minutes at room temperature and a full de-mould time of 24 hours. To achieve faster cure speeds, elevated temperatures may be used. Available in a range of different sized kits to suit any requirement, the most popular kit sizes are 1.1kg and 5.5kg; both are available online from www.techsil.co.uk with next working day delivery.
