Data sheets

SILPURAN® 2400/25 A/B can be used for flexible moulding applications in prosthetics.

Components A and B of SILPURAN® 2400/25 A/B are delivered ready to use in drums.

The components are mixed homogeneously in an A to B ratio of 1 : 1 and vulcanize rapidly at temperatures over 100°C. In a given application the required curing conditions (temperature and time) will also depend on the size and thickness of the specimen.

The fabricator must carry out preliminary tests to determine the optimum conditions for a particular application.

Detailed instructions for preparation and use are given in the product data sheet “Wacker RTV-2 Silicone Rubber – Processing.”

Important note:
The platinum catalyst is contained in component A.

Only A and B components with the same batch number may be processed together!


The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
