PETROCHEMICAL
PLATING & COATINGS
Fasteners used in the Petrochemical and Oil & Gas industry can be subjected to the most adverse conditions and require total corrosive protection. For this reason we are able to offer a wide range of coating and finishes. The most popular coatings, used on an everyday basis, are Zinc Plating and Hot Dipped Galvanised which are available from stock on certain materials.
The full list of coating and finishes we offer include:
- Zinc
- Zinc Clear
- Zinc and Yellow/Bichromate
- Zinc Nickel
- Nickel
- Electroless Nickel Plating
- Xylar Coating
- PTFE (Xylan®)
- Molykote®
- Zinga®
- Sermaguard
- Hot Dip Galvanising
- Dacromet
- Silver
- Copper
- Phosphate
- Sheradized
- Cadmium
- Chromium
- Magnigard
- Molybdenum Disulphide
- Epoxy Coatings
Some of the various processes involved when plating and coating fasteners include the following:
SURFACE CLEANING
Metal surfaces are cleaned by chemical or thermal degreasing process
SURFACE BLAST
Metal surfaces are abrasive blast as required
BASECOAT APPLICATION
All surfaces are coated with phosphate, zinc base coat, primer, or ceramic metallic base-coat per the customer specification
TOP-COAT APPLICATION
All surfaces are sprayed with a Fluoropolymer® topcoat for a total dry film thickness of 1 to 1 ½ ml.
THERMAL CURE
Parts are thermally cured in controlled ovens per manufacturer’s procedures to ensure corrosion protection and adhesion
