Definitions
- the present invention relates to a continuous process for surface-coating of metal substrates with planar surfaces, such as coil or sheet materials, on a coil-coating line for provid ⁇ ing a durable and corrosion protecting coating on the metal surface.
- the first layer is a paint material with adhesive properties.
- suitable paint materials are polyester, vinyl or latex paints.
- chlorine-free wet paint such as latex, polyester, fluo- rocarbon polymers, e.g. P F2, or polyurethane (PUR) is app ⁇ lied. Said wet paint is cured (dried) and cooled after appli ⁇ cation.
- the paints are applied according to conventional techniques, such as roller coating, spray coating, curtain coating, etc.
- the drying is also performed by conventional methods, such as IR-tubes, induction or convection heating.
- the chlorine-free plastic sheet or foil is applied directly upon the hot paint surface.
- the plastic sheet is applied directly upon the hot paint surface by lamination, e.g. using a pressure roller.
- the second layer the chlorine-free plastic sheet or foil, has a thickness of from 10 to 300 ⁇ m.
- the third layer, the pigmented, chlorine-free paint is app ⁇ lied to a thickness of from 10 to 150 ⁇ m dry film, preferably from 10 to 50 ⁇ m.
- SUBSTITUTE SHEET As metal materials with generally planar surfaces which can be treated with the surface coating process according to the present invention the following may be mentioned: cold rolled steel, metallized steel, stainless steel, galvanized steel, aluminium, etc.
- the sheet metal is preferably pretreated chemically by usual methods, such as pickling, phos ' phatizing, chromating, etc.
- a water borne acrylic paint (68760-34, Coilon laqua from Becker IndustrifSrg, Sweden) is applied by reverse -roller coat to a thickness of 10-25 ⁇ m dry film, drying/curing at 180°C PMT (peak metal temperature).
- Second layer Directly upon the previous hot layer a clear thermoplastic acrylic sheet (Korad from Polymer Extruded Produ ⁇ ts Inc., USA) and a thickness of 75 ⁇ m is applied by laminating roller and a pressure of 3.5 kp/cm .
- an acrylic water borne top coat (EJ 644-9302, Coilon Acrylic latex from Becker Industrifarg AB, Sweden) is applied to a thickness of 20 ⁇ m dry film, by reverse roller coat, drying/curing at 180°C
- Example 1 The same a ⁇ Example 1 with the following exception: Instead of hot galvanized steel, pretreated with "Bonder 1303" Alu-zinc coated steel is used.
- Example 1 The same as Example 1 with the following exception: As third layer is used a polyester 'top coat (DJ216, Coilon polyester from Becker Industrifarg, Sweden) instead of EJ644.
- DJ216 Coilon polyester from Becker Industrifarg, Sweden
