Epoxy & Polyurethane
Liquid Systems

Best Results guaranteed.


With their excellent mechanical and chemical properties, RAKU® TOOL gelcoats ensure a whole host of premium surface qualities.

A wide range of surface properties (rigid to flexible and abrasion resistant to polishable) can be obtained by applying just a thin layer.

The two-component epoxy systems and the polyurea system are available with both long and short pot lives and also with different degrees of temperature resistance.

RAKU® TOOL gelcoats are easy to apply and process.

Coupling coat

The RAKU® TOOL coupling coat is a prefabricated two-component epoxy system. It ensures a good adhesion of the gelcoat to the backing and is applied with a brush in a thin, uniform layer.

Depending on the operating conditions, the backing can be made from casting resin, tamping, fiber laminate or laminating paste.

Coupling coats are used to make tools, molds, parts, and auxiliaries.

The prefabricated RAKU® TOOL coupling coat makes work easier and is sure to impress with its excellent heat resistance, outstanding interlayer adhesion, and uniform consistency (e.g. thixotropic properties).

Casting resins

The RAKU® TOOL range of casting resins for both full and face casting includes epoxy, polyurethane, and polyurea systems.

These systems are available with varying degrees of temperature resistance and different pot lives. The latter can be adapted in some cases based on the hardener selected.

The resins have a number of impressive features, including good processing and venting properties, excellent resistance to chemicals, high resistance to abrasion, and a hard surface.

RAKU® TOOL casting resins are used for modeling in general and to make items such as foundry patterns and copy models, jigs and fixtures, and working models for the ceramics industry.

Full casting - the benefits: quick and easy work process, with no need for a gelcoat. It is suitable for smaller as well as larger castings.

Face casting – the benefits: a smaller amount of casting material is required, superior dimensional stability of the casting due to lower shrinkage, and special surface properties can be achieved (from flexible to hard). Face casting is suitable for large castings.

Fast cast resins

The range of RAKU® TOOL fast cast resins consists of two-component polyurethane systems that are used either filled or unfilled and can thus be cast in thin or thicker layers with various pot lives.

The resins are easy to mix and used to produce foundry models, core boxes, negatives, pattern plates, checking casts, copy models, vacuum forming molds, and jigs for trimming prototype parts.

RAKU® TOOL fast cast resins are sure to impress with their rapid cure and short demold times, excellent heat resistance, good moisture resistance as well as very high strength. They also allow for a high degree of filling.

Sealers are mainly used to seal pores in RAKU® TOOL board materials with densities of less than 1.0 g/cm3, especially working boards WB-0691 and WB-0700 and the range of modeling boards.

Release agents ensure the absence of any damage or remaining traces when parts are removed from molds.

Fillers are added to the basic material in defined quantities to make specific changes to the processing and mechanical properties.

Density 0.60-0.85 g/cm3 - filler for EP and PUR systems


Density 2.4 g/cm3 - filler for EP and PUR systems
