VICOTE Coatings can be applied using electrostatic, conventional dispersion spray or thermal spray techniques.
VICOTE 700 Series, Electrostatic Powder Coatings
- Electrostatic Equipment - VICOTE 700 Series powder coatings can be used in conventional electrostatic coating equipment either in manual or automatic powder booths using a negative Corona charge.
- Preparation of the part/substrate - It is important that the parts/substrate be prepared properly in order to gain the full advantage of a VICOTE Coating.
- Removal of the old coatings - It is essential to remove all previous coatings, oil, grease and other deposits be removed before preparing the part for grit blasting and subsequent coating.
- Grit blasting the part/substrate - Use clean alumina grit, 60-80 mesh (250-177 microns), for grit blasting the metal surface
- Drying - It is recommended that VICOTE Coating powders be dried in an air circulating oven at 150°C (302°F) for 3 hours or 120°C (248°F) overnight before use.
- Coating with Powder - To apply VICOTE Coatings evenly; flow out the coating as 380-420°C (718-788°F) part surface temperature.
- Thickness correction - Thickness should be checked, after the part is cooled. If the part does not have the desired thickness, then clean the part with a clean rag and solvent, and heat it in an oven at 380-420°C (716-788°F).
- Cross contamination - It is recommended that dedicated spraying equipment be used for applying VICOTE Coatings or at least equipment that has been thoroughly cleaned to remove all traces of other polymers.
- Thermal Spraying - The ability to apply VICOTE Coatings using a thermal spraying process offers advantages and design freedoms for some applications.

VICOTE Coatings 800 Series, Liquid Dispersion Coatings
- Dispersion Coating Equipment – VICOTE 800 Series liquid dispersions can be applied using conventional gravity suction HVLP or pressure spray coating equipment.
- VICOTE Coating Material Preparation – If liquid dispersion formulations soft settle they can be easily re-dispersed by hand mixing or by the use of a roller or stirrer.
- Viscosity - VICOTE Coating is generally suitable for spray application as supplied; however, some viscosity adjustment may be necessary depending upon the type of application equipment and spraying equipment employed.
- Preparation of the part/substrate – Final coating quality demands careful surface preparation, remove oils and greases, grit blast, and rinse each piece to remove gritty residue.
- Application equipment and techniques – VICOTE Coating liquid dispersion formulations may be applied with standard air spray equipment.
- Film thickness/multiple coats – VICOTE Coating liquid dispersions may be applied at 1-2 mils (25-50 microns) per coat; multiple coats may be applied in proper cure sequences.
- Stoving cycles – Stoving time is directly related to the melt temperatures of VICOTE Coating and the mass of the part/substrate temperature.
