hwr stands for highly weather resistant and represents the current world´s best standard in the coating of aluminium surfaces covering the entire RAL range of colours. heroal dur hwr meets the highest class 2 quality requirements of Qualicoat and the master quality of GSB. Class 2 Qualicoat and/or GSB master quality powder coatings must withstand the so-called Florida weathering test for 36 months without damage and with only minimal, clearly specified changes in the coating surface in order to be classed as highly weather-resistant. In this special test, coated aluminium sheets for outdoor use are tested for their behaviour with regard to residual gloss maintenance and colour stability under the natural high UV conditions in the US state of Florida. heroal dur hwr coated sheets have passed this intensive ultraviolet radiation for three years with flying colours. This corresponds to a service life of at least ten years in the Central European climate.

 

 

 

 

 

 

The “Dicklack” is applied to specially pre-treated aluminium strips and annealed in the double-sided coil coating process. It is a particularly abrasion-resistant film system based on a high quality polyurethane strengthened with nylon. The test criteria and analyses surrounding the film development and production monitoring, show that heroal “Dicklack” has very good weather resistance, is environmentally friendly and has a high colour intensity and colour fastness against UV radiation. This means heroal systems are functional and easy to care for over time.

 

 

 

 

 

 

The individual and extraordinary Raffaello coating was developed and patented in Italy.

This structured coating differs radically from conventional coatings: It is not polished and glossy but structured and rough-textured.
