WEICON Urethane

Flexible Casting and Coating Resin with high impact strength and abrasion resistance

WEICON Urethanes are 2-component polyurethanes that cure at room temperature to tough rubber-like materials, remaining flexible at temperatures down to even -60°C.

WEICON Urethanes adhere to a variety of materials such as metals, concrete, rubber, wood, fibreglass and many others.

They are also suitable as flexible coatings in connection with WEICON Plastic Metal (epoxy) systems.

Due to their low sensitivity to humidity they can also be used for coatings in thin layers and have a remarkably high tensile and tear strength.

For making:

Vibration dampers
Assembling jigs
Flexible seals
Rubber-like prototypes
Foundry patterns and forms

For repairs on:

Conveyor belts
Solid rubber tyres
Conveyor rollers

For coatings on:

Rollers
Contrifuges
Polishing drums
Tanks
Chutes and funnels
Pumps
Bulk cointainers
Dry and wet mixers
Cyclones
Housings
Loading areas

In addition, WEICON Urethanes are excellently suitable as vibration or insulation protection of machines.

Pretreatment of the surface

The surfaces must be clean, dry and degreased. Almost every surface soiling like oil, grease, dust and dirt can be removed with WEICON Surface Cleaner or WEICON Sealant and Adhesive Remover (old paint residues). If the surfaces are badly soiled or smooth, the adhesion can be optimized by sand-blasting with suitable grain size or by mechanical roughening.

The use of a primer can improve the adhesion on certain surfaces (for details see brochure).

Important Note:
All specifications, recommendations and techncial data are based on laboratory tests under optimum conditions resp. on practical experience. They have been compiled most carefully. Nevertheless, a claim cannot be derived from them. We therefore recommend to carry out own tests before application.
