    Stovrite SC specialise in 3 types of phosphate metal coatings as listed below.

    Manganese Phosphate metal coatings

    DEF STAN 03-11 Class 1.

    FEATURES – Manganese Phosphate metal coatings or Parkerizing is formulated to produce a non metallic, corrosion resistant coating on iron and steel surfaces. Carried out by dipping of components.

    Class 1 BENEFITS

    • Manganese Phosphate or Parkerizing produces a corrosion resistant crystalline coating which forms an excellent base for the adhesion of organic finishes and adhesives for the bonding of rubber.
    • Parkerizing produces an oil-absorptive coating, which permits rapid break-in of moving parts by preventing metal-to-metal contact between the bearing surfaces.
    • Increases lubrication of treated surfaces.
    • Does not appreciably reduce the gloss of single coat paint finishes.

    Zinc Phosphate metal coatings

    DEF STAN 03-11 Class 11 and Type 2.

    FEATURES – Phosphate is an acidic liquid chemical which when diluted in warm water gives a fine, smooth zinc-calcium phosphate coating on steel and zinc surfaces. Carried out by dipping of components.

    Class 11 BENEFITS

    • Phosphate coatings are smooth – even after alkali or acid pre-cleaning.
    • Protects iron and steel under paint against rusting in corrosive enviroments.
    • Improves paint adhesion even where metal deformation occurs.
    • Does not appreciably reduce the gloss of single coat paint finishes.

    Iron Phosphate metal coatings

    DEF STAN 03-11 Class IV and Type 4.

    FEATURES – A liquid chemical which when diluted in warm water will simultaneously degrease and form a thin, protective phosphate conversion coating on steel, zinc and aluminium surfaces. It can be used by hot spray processes. Phosphate coatings on steel are usually 0.2 – 0.4 gram/m2 and comply with DEF STAN 03-11/3 Class IV and EN 12476:2000 Feph, previously BS 3189 (1973) Type 4.

    BENEFITS

    • Degreases normally oily surfaces.
    • Treats steel, zinc (Mazak/Zintec/Galvanised) and aluminium.
    • Improves paint and powder adhension.
    • Operates at low temperatures – reduced energy.
    • Forms very little sludge – low maintenance costs.
    • Concentrated product for economy.

    We also provide other type of metal pre-treatments such as Alocrom 1200 and Surtec 650. for more information, please contact our team of friendly professionals on 0191 438 6612.
