Interior coating for aluminium packaging, essential for protecting the quality of the products and preventing damage to the material with which they come in contact.
The excellent quality of the protaral® interior coatings, their reliability and immediate availability worldwide are key factors behind the success of these products over the years, above all in demanding industries where high quality product appearance is essential, such as the pharmaceuticals & cosmetics and food & beverage markets.
aluminium collapsible tubes
Lacquers for the internal protection of aluminium collapsible tubes based on epoxy, phenol and amine resins.
for monobloc aerosol cans
Epoxy-phenol lacquers for the internal protection of aluminium monobloc aerosol cans.
water-based coatings for aluminium
Water-based epoxy-phenol lacquers. The latest product coming from the Weilburger research laboratories, protaral<sup>®</sup> Hydro is the first product in a new line of water-based interior coatings for use in aluminium packaging which stand alongside the existing proven line of products for exterior applications.
protaral® is a line of internal coatings for aluminium packaging, indispensable to preserve the quality of the products and the integrity of the material with which they come into contact. The high quality of the range of protaral® internal coatings for aluminium packaging, their reliability and their immediate availability throughout the world have resulted in success over the years especially in sensitive areas that require high quality standards such as the food, pharmaceutical and cosmetics industries.
In addition to a range of protaral® internal coatings for aluminium packaging, WEILBURGER offers lines of glazes for the external decoration of flexible aluminium tubes, easy to apply and compatible with many types of inks. In addition to the classic version in white, the external coatings for aluminium are available in different colours, transparent, opaque, metallized, pearled and glittery, both opaque and glossy. With high chemical resistance to alkali and acidic products and to diluents, these glazes stand the test of cold compression at a temperature of -20 °C and are ideal for a wide range of applications.
protaral® is an interior coating with low emissions of volatile organic compounds and high solids content. As a result: increased productivity and very low VOC emissions. So protaral® coating systems are immediately available anywhere in the world, preserve the product and protect the environment. Therefore WEILBURGER constantly invests in research for the improvement of its protaral® internal and external coatings for aluminium and to respond to new market requirements.
During recent years the Research & Development Department of the German Grebe Group, to which WEILBURGER belongs, has created innovative solutions subsequently adopted world-wide.
protaral® is a continuously developing product: tests and research are carried out every day on new applications which allow the Group to honour their mission, namely: to offer safe, reliable and innovative solutions with full respect for the environment and people.
Continuous investment in research and development has recently allowed WEILBURGER to develop a line of water-based interior coatings for aluminium packaging, namely protaral® Hydro, which from its initial applications has passed the various resistance, flexibility and durability tests with outstanding results.
Currently our research staff are working on a new product totally free of bisphenol with promising results.
