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.
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.
