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
- 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
- Mechanical resistance
- Adhesion properties
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.
‘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.
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.
Booster lubricants reduce the wear and tool pollution during pressing of metal sheets.
