Hawiflex® polyurethane cast – material selection according to use
The special feature of this method is that the coatings fulfil high demands with respect to dimensional accuracy, long service lives and reproducibility. As a result, our high-quality Hawiflex® polyurethane coatings offer clear advantages in the casting process compared to conventional coating techniques.
The significant advantages with respect to service life which are usually achieved are explained by the fact that in the casting process we can access our wide range of materials. This means that the material selected is ideal for the respective application.
Sprayed Hawiflex® polyurethane – the alternative to rubber coating
In order to produce a large-surface coating, a spraying process during which the plastic is applied similar to the airless process, is ideal. Coatings are seamless and do not form any points at which the coating could detach. Consequently, our spray coatings are particularly impervious to fluids. More material can be applied to areas susceptible to wear. As a result of this material concentration, a marked longer service life can be achieved compared to cladding with board products, whilst the amount of material used is the same. Components coated with Hawiflex® polyurethane are extremely resistant against abrasion, corrosion and chemicals and offer excellent sliding properties. The sound-insulating effect provides a considerable noise protection. The best non-stick properties ensure the quickest cleaning times. The optionally available structured surface is particularly effective against caking. As there are no resulting tooling costs, the spray process is particularly suitable for prototypes and extra large work pieces.
Particularly suited for coating:
- Automotive parts
- Concrete buckets
- Conveying screws
- Pump components
- Supporting rollers
Roller Coating – high resilience and wear protection Roller covers
On the basis of our extensive experience we have been able to develop special formulations for requirements that involve high demands with respect to dynamic loads and wear resilience with excellent recovery behaviour.
For roller covers we supply co-ordinated formulations in the hardness range from 55° to 95° Shore A. Furthermore, we offer products of a special quality for use under elevated thermal conditions, as well as excellent hydrolytic stability.
Raw material systems which take into consideration the functions of a high-quality roller cover have also been developed for the special requirements in the coal, steel and aluminium industry. Considerably longer service lives are achieved compared to rubber-lined rollers.
