MAINTENANCE OF COATED STEEL
1. CLEANING
1.1 General rules
• Cleaning must be effected with water and neutral soap.
• We recommend cleaning with soft cloth, accurate rinsing and drying of the surface
• Avoid the use of abrasive products.
1.2 Little stains removal
• Varius substances ( such as nail enamel, rouge, polish, ink, tar) may penetrate into the film surface causing permanent staining.
Note:
It is preferred to avoid solvents and such as acetone, toluene, ethylacetate, thrichloroetylene, perchloroetylene.
2. REPAIRING OR PAINTING OF PVC COATED STEEL
2.1 Preliminary operations
Before applying the enamel, clean the surfaces with neutral detergents preferably diluted with water, rinse and dry accurately .
2.2 Usable materials
Repairing or painting of PVC coated steel can be effected with the following products, witch can be found on the market:
• Water based acrylic enamel ( for repairing or painting).
STORAGE AND PROCESSING OF SHEETS AND COILS
1. STORAGE
1.1 Sheets and coils must be kept under shelter, in order to avoid sudden changes in temperature and the consequent condensation. The
presence of humidity may cause whitish stains (white oxide) that could endanger the adhesion of polyurethane and provoke the
alteration of the coating.
1.2 Sheets covered with the adhesive film for temporary protection must be stored away from heat sources and sun - rays.
2. PROCESSING
2.1 Sheets and coils should be processed within 6 months of shipment, with the most suitable equipment in order to avoid abrasions on the
surface of the coating or fissures of the coating and of the zinc layer.
2.2 Bending and roll forming machines should consider the final thickness and possible tolerances to avoid re-rolling processing.
2.3 We suggest not processing our materials at temperature inferior to 18 degree C°.
