SikaBlock® Model and Tooling boards Whether design or data control model, whether gauge or core box – SikaBlock® board materials are the optimum products for all applications. There are 12 different board types with densities of 0.08 to 1.2 kg/dm3. They are available in different dimensions and thicknesses of up to 2500 x 1200 x 200 mm. In accordance with requirements, the materials also differ in respect of their structure, as well as their mechanical and thermal characteristics. Numerous quality checks help to monitor compliance with these standards. For us, certification to DIN EN ISO 9001...

Biresin® Model and Mould Making Pastes The manufacture of high-quality, completely joint-free design, styling and cubing models as well as moulds is the domain of Biresin® Model pastes. They are mainly processed on 2-component mixing and metering machines. The cured resin systems are easy to finish to their correct dimensions by mechanical means. The results are joint-free, smooth surfaces with a high level of precision which can then be covered with layers of paint. Biresin® M72 – the fastest model paste in the market Biresin® M73 – high heat distortion temperature, e.g. for wind power blades...

Biresin® Low Pressure RIM-Systems Application: n Curing PUR resins for use on 2-component mixing and metering machines for the manufacture of individual parts or series manufacture of several thousand pieces n Simulation of materials of serial production (like rubber, polyethylene, polypropylene, ABS, PVC, and others) in stage of development and preproduction for automotive industry, for household appliances, for rail vehicles, in aviation, in boat building and for other technical parts n For small parts (< 0.1 ltr.) to big volume parts (appr. 20 ltr.) Biresin® Low Pressure RIM-Systems 80 2500...

Biresin® High Performance Composite Systems Aimed at part production and mould making applications in the transport, marine, wind energy and other industries, these high performance composite resins are designed to meet the highest standards of production process efficiency and end-use performance. For infusion processes lower viscosity resins are available and for wet lay up, pultrusion and filament winding there are resins with optimized viscosity. With different hardeners the potlife can be varied. The resin/hardener systems are specially designed for the three application temperature ranges...

Biresin® Gelcoats and Laminating Systems n Gelcoats Biresin® Gelcoats are very easy to apply and specially formulated. In accordance with their particular application, they have the necessary resistance to external influences such as mechanical, thermal or chemical stress. In other cases, the fact that they are easy to work and colour plays an important role. The gelcoats are used in the construction of models, moulds and tools as well as in composite applications. n Laminating and Multipurpose resins Biresin® Laminating and Multipurpose Resins Biresin® Laminating and Multipurpose resins offer...

Biresin® Fastcast Resins n Biresin® Fastcast resins Biresin® Fastcast resins offer high flowability, a quick curing and this result in quick demoulding. They are easily workable. The wide range of products is characterised by filled and unfilled systems. n Filled Biresin® Fastcast resins Filled Biresin® Fastcast resins are especially suitable for making e.g. master and core models and negatives with large dimensions and are characterized by low shrinkage. n Unfilled Biresin® Fastcast resins The unfilled Biresin® Fastcast resins are usually used for making detailed models and mouldings with thin...

Biresin® EP- and PUR-Casting Systems The large range of Biresin® Casting resins based on epoxy and polyurethane can be used in many different ways. The resin systems are highly resistant to mechanical or thermal influences. The system selected depends on the casting procedure in question, e.g. mass casting, backfill or facecasting. n EP-Casting resins In accordance with their particular application, the Biresin® EP-Casting resins have a good resistance to chemical stress and / or abrasion. Therefore they are suitable for the quick and inexpensive manufacture of production equipment such as foam-,...
