Zinc Phosphate Coating Chemicals

We can divide zinc phosphate coatings into three sections according to application areas:
- Application for preventing abrasion caused by friction before metal forming processes such as cold drawing, cold forging, deep drawing,
- Application for increasing paint adhesion before electrostatic powder coating and wet painting,
- Application for increasing wear resistance and corrosion resistance with protective lubrication.

When used before forming of metals, coating weight of 5 - 15 g/m2 is usually required. It is most commonly used in wire and tube drawing processes. The phosphate layer is firmly attached to the metal surface and reduces friction in the dies and molds during the cold drawing process, allowing these operations to be carried out easily.

The phosphate layer remaining on the surface after the drawing operation creates high corrosion resistance during storage and transportation and prevents rusting. Phosphate coating is of great importance in high carbon wire drawing industry such as steel rope, spring, welding wire, pc wire, pc strand production. It provides continuity on the surface for multiple drawing operations and enables high drawing speeds. It enables difficult cold forging operations in the production of bolts and screws and ensures long service life of molds.

If zinc phosphate coating will be applied under paint, a coating in the range of 2-6 g/m2 must be obtained on the metal part. Making a uniform coating with thin crystal structure is important in terms of adhesion to paint and to provide corrosion resistance in harsh environmental conditions.

The desired coating weight for protective oil application is in the range of 10-35 g/m2. Zinc phosphate coating with coarse crystal structure and high coating weight retains the protective oil and provides an effective corrosion resistance. It is widely used for auto parts, fasteners and machine parts.

PHORYL ACT 15 - Activation

Used just before immersion zinc phosphate coating stage. Provides fine crystalline uniform coating. Can be used in pre-painting zinc phosphate and wire/tube zinc phosphate coating lines. High paint adhesion and high corrosion resistance is achieved by using in the phosphating line before painting.

PHORYL Z 100 - Pre-paint Application

It is used with accelerator in dipping zinc phosphate coating lines for iron and steel materials. With 2-4 g/m2 coating weight, it provides high corrosion resistance and good paint adhesion before powder coating and wet painting applications. Due to its fine crystalline coating feature, no activation is required.

PHORYL Z 26 - Pre-paint Application

One-component product suitable for iron, steel and especially cast materials. Used in immersion zinc phosphate baths without the need for accelerators. No need to use an activation bath as it forms fine crystalline coating. Provides good adhesion and high corrosion resistance for electrostatic powder paint and wet paint.

PHORYL Z 36 - Pre-paint Application

Easy-to-use one-component product for iron, steel and cast materials. It is generally preferred before powder paint and wet paint applications. It is used without the need for an accelerator. When used with activation, very high corrosion resistance and salt spray test results are obtained for the parts to be painted.

PHORYL ACT 25 - Activation

It is used in spraying zinc phosphate coating systems. Slightly alkaline powder product that provides a fine crystalline, uniform and dense coating. It is used together with zinc phosphating in wet paint, powder paint and cataphoresis painting. It is an effective product for high paint adhesion and advanced corrosion resistance requirement.
