SikaBlock® tooling boards

We offer an extensive range of application-oriented system solutions consisting of special modelling and tooling boards together with matching adhesives and filler pastes.

The boards are based on polyurethane (PUR) and epoxy (EP) and are used for building models, moulds and tooling.

Depending on requirements for the model or mould, customers can choose between different plates with a density of 0.08 to 1.3 kg/dm³.

The broad range of different densities means we have the right plate for almost any application in terms of surface quality and mechanical properties.

Special EP plates provide high temperature resistance combined with excellent dimensional stability, thanks to a low CTE, and can be used for prepreg applications.
