Chromium-free

Increasing concerns over the health and ecological effects of hexavalent-chromium has inspired the development of alternative solutions. For example, architectural our chromium-free Iridite EXD, NR2-I, NR4-T processes use are meet both GSB and QUALICOAT approval systems.

Advantages

Until now, most non-chromium conversion coatings have been based on a combination of organic polymers and fluoride compounds. While these types of products have excellent paint adhesion characteristics, in most cases, they have no corrosion resistance properties.

基于缺陷,MacDermid Enthone发展188金宝搏官网版下载ped the Iridite range of chromium-free coatings that has shown to be both safe and effective as a true replacement for the hexavalent chromium systems.

它们为涂料和粉末涂料提供高附着值,以及(适用)其右侧的优异耐腐蚀性。

铱星NCP.

Increasing concerns over the health and ecological effects of hexavalent-chromium have inspired the development of alternative approaches and technologies for various coating types.

At the center of the innovation, efforts are companies like MacDermid Enthone, whose development of chromate conversion coatings for plated coatings helped seed developments in the field of aluminum treatments.

Advantages

到目前为止,大多数非铬转换涂层一直基于有机聚合物和氟化物化合物的组合。虽然这些类型的产品具有优异的涂料粘附特性,但在大多数情况下,它们没有耐腐蚀性。

基于该缺陷,MacDermid Enthone开发了188金宝搏官网版下载一种产品系列,其显示为六价Chrome Systems的真正替代品既安全有效...... Iridite NCP。

铱星NCP.provides both high adhesion values for paints and powder coatings as well as excellent corrosion resistance in its own right. This means that even unpainted areas of aluminum are protected against corrosion.

Meets environmental directives

铱星NCP.is the safe, reliable and cost-effective alternative to chromate based pre-treatments for aluminum and has been developed in response to the ELV, RoHS and WEEE directives.

铱星NCP.does not contain Lead, Cadmium, Chromium(hexavalent or trivalent), Mercury or PBB / PBDE compounds.

Applications

The coating exhibits bare, unpainted, corrosion resistance that is equal to hexavalent chromates on many aluminium alloys. The coating can be used as a final finish and can also serve as a base for paints, high-performance topcoats, powder paints, lacquers, or as a base for rubber bonding.

Alternatives

When the application is for a paint base only, then Iridite EXD may be considered.

Iridite EXD

QUALICOAT APPROVED

Iridite EXD is an environmentally friendly process developed for the chemical pre-treatment of aluminum and its alloys prior to coating. Its formulation is in complete compliance with the latest European environmental guidelines (ELV, RoHS, WEEE) and does not contain lead, cadmium, chromium, mercury nor organic or inorganic polymer compounds.

Iridite EXD is a non-chrome conversion coating process that produces an inorganic, almost transparent conversion coating on the degreased and deoxidised aluminum substrate. This coating will provide the perfect base for adhesion of subsequent paint or powder systems and will impart a high corrosion resistance to these systems. Iridite EXD is suitable for powder coating, wet paint, lacquer and as a base for rubber bonding.

Iridite EXD is also an ideal pre-treatment for zinc-coated steel substrates (HDG)
