PrimeCoat® Z90x products are high performing chemicals from Coil Coating Technologies B.V. PrimeCoat® products have been developed based on an in-depth knowledge of customers’ production processes and meet or exceed all critical demands.

PrimeCoat® Z90x products are water-based functional chemical passivations purposely developed to improve corrosion resistance of galvanised steel and other Zinc based alloys.

Additional properties of the PrimeCoat TOC chromefree Z90x are:

reduction of the friction of the metal surface in forming operations
Improved bonding and adhesion properties

PrimeCoat® Z90x products are Phospate based and do not contain hexavalent Chromium Cr(VI) or any other form of the element chromium. This product line is also free of SVHC substances. PrimeCoat can replace traditional chromium based TOCs and passivations withoug giving in on quality. A PrimeCoat treatment ensures excellent appearance, even at higher layer weights.

Typical galvanized steel surfaces that will benefit from PrimeCoat Z90x-series are:
Zinc coated steel (Z), Zinc Magnesium (ZM), Galvalume (GA), Aluzinc (AZ) and Electro galvanized (EG). Metal coated with PrimeCoat® Z90x products is combining excellent tribological, post-painting
and adhesive bonding properties.

Your advantages with PrimeCoat® Z90x-series

TOC and/or Passivation with one product
Good paint adhesion and lubrication properties to reduce galling in deep drawing
operations
Low dry film coating weight
Excellent corrosion resistance properties
Compatible with most paint systems
Chromefree, SVHC free, water-based chemistry and VOC (solvent-free)

Modular system Z90x series

A unique aspect of PrimeCoat® Z90x products is that the product technology is modular which enables solutions tailored to specific customer processes. By changing the product concentration or adding specialty additives product certain properties can be enhanced while maintaining perfect overall quality. At a higher application concentration the product obtains more TOC based characteristics, such as improved:

Corrosion resistance
Lubrication
Mechanical resistance
Adhesion properties
Anti-fingerprinting

At a lower application concentration (<50%) it can be used as a very good passivation. Whatever your process or need PrimeCoat® is the preferred product.

Thin Organic Coatings

Thin Organic Coatings (TOC’s) are applied in a continuous process to hot dip galvanized steel strip and other metal substrates, and can offer a wide range of benefits from anti-fingerprinting to improving, forming and enabling enhanced corrosion protection.

Passivation

‘White rust’ the enemy of zinc coated steel strips, is in itself a form of corrosion that occurs during storage and is unacceptable for critical applications in, white goods, construction and other industries.

Pretreatments

Durability and extended end-use life are demands that consumers take for granted and of which they expect continuous improvement year on year. Paint adhesion and corrosion resistance are critical factors in keeping end-use applications in a condition that is expected to remain in place for their usable life time.

Cleaners and specialty additives

Oils and greases used during processing as well as other forms of surface contamination must be removed. This can be achieved using either acid or alkaline based cleaners depending on the nature of the contamination and the type of metal substrate.
