Platsil HTS-25 Fast is a high-performance, platinum-catalysed silicone rubber. With excellent tear strength, tensile strength and elongation properties, this silicone stands up to the rigours of repetitive demoulding and/or stretching. Common applications include concrete casting, medical modelling and prototyping. Fast as the name suggests, this silicone has a 15 minute pour time with a 3 hour demould.

Other silicones in the HTS-Series include Platsil HTS-25 (a slower-setting version of the HTS-25 Fast) and Platsil HTS-40 (Shore A40).
Additional Key Characteristics
– Good Chemical Resistance – a good moulding choice when planning to cast polyesters, polyurethanes, epoxies and more.
– Excellent Release Properties – making release agents unnecessary in many mouldmaking applications.
– Polytek Additives – vary the viscosity, reduce or speed up the cure and demould times, and alter the colour of the cured rubber.
