In order to minimize corrosion, the automobile industry is now considering the replacement of mild steel with zinc-coated or galvanized steel. When applying the putty, it must be spread evenly, makingeven coats from one end to the otherand exerting appropriate pressure on the spatula. Bayha also discloses that the metallic surface may also be chemically etched to maximize adhesion of surfacing materials to the metal surface. It is comparatively easy to visually distinguish between iron and zinc, since they look different. 1(a) & 1(b) are shown a side view of the laminated metalpanel 2 coated with body putty 4. The etching solution of Example 1 was applied with a paint brush for 45 seconds and then rinsed off with distilled water. Chemically etching the surface of galvanized steel with a metal salt that is more electropositive than zinc provides improved adhesion for an unsaturated polyester resin based putty. Standard body putty has successfully been used to repair damaged steel surfaces of automobile bodies. ;ASSIGNOR:FORSTER, WOLFGANG C.;REEL/FRAME:005362/0912, ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:FORSTER, WOLFGANG C.;REEL/FRAME:005362/0912, PATENT EXPIRED DUE TO NONPAYMENT OF MAINTENANCE FEES UNDER 37 CFR 1.362, Method for improving the adhesion of a repair coating to a previously coated substrate, Method for economically repairing a defective spot on a new motor vehicle exterior paint coat, Method Of Making Tailored Core Laminated Sheet Metal, Main / lateral connection liner with resin putty mainline portion, Phosphatization of steel surfaces and metal-coated surfaces, Method for production of metal sheet covered with polyester resin film, Method and compositions for preventing corrosion of metal substrates, Method of preventing corrosion of metals using silanes, Method of treating metals using amino silanes and multi-silyl-functional silanes in admixture, Process for providing a precoated steel sheet having improved corrosion resistance and formability, Method of treating metals using vinyl silanes and multi-silyl-functional silanes in admixture, Metallic surface treating agent for forming composite film, Coating method of roasting and quenching steel using chromium-containing aqueous organic resin, Phosphating solution for metal substrates, Non-chromium type surface treated metallic material, Process for coating a workpiece of steel with an anti-corrosive agent, Aluminum substrate treatment material with excellent coating adhesion and corrosion resistance, Formation of composite film on aluminum or aluminum alloy surface, Manufacturing method of resin coated rustproof steel plate with excellent electrodeposition coating property, Chromium-containing conductive anticorrosive and anticorrosion method, High corrosion resistant surface treated steel sheet and its manufacturing method, Metal surface treatment composition and metal surface treatment method, Covered steel wire excellent in corrosion resistance, The state of metal surfaces after blasting treatment Part I: Technical aluminium, Copper or copper alloy and surface treatment method for plating the same, Pre-coated steel sheet excellent in corrosion resistance and fingerprint resistance, Lapse for failure to pay maintenance fees, Lapsed due to failure to pay maintenance fee, Information on status: patent discontinuation.

The process employs an aqueous ferric sulfate etching solution. Fills well the irregularities after processing the weld. For deep dents upto 3mm, apply in several layers, allowing each layer to dry before applying the subsequent layer. Everywhere, where a large-area spreading. First of all,check that the working toolshave no traces of putty or hardener used in previous repairs, in order to make a smooth and regular application on the surface. Before starting with the filling, the painted damaged edges to be repaired should be levelled, sanding the surface with a grit sandpaper between P80 P120 and 5mm orbit,depending on the repair. The Carsystem Steel polyester hard putty is a special putty with fast drying times and an extremely high degree of hardness for filling very deep imperfections or re-forming of deformed edges.

The putty was allowed to cure at room temperature for 24 hours, after which the specimens were immersed in 95 C. distilled water for 2 hours. In FIGS. 1(b), the area 6 where loss of adhesion occurred after the 90bend, is referred to as the "gap". Formulated with ZNX-7 for improved adhesion. Let us now look at the steps that will allow optimising the putty application process, while increasing the profitability of the repair. 18. Aug 03 The extent of the etching can be controlled by the concentration and amountof the ferric chloride solution applied. The putty is allowed to harden and is subsequently shaped to conform to the desired contour of the automobile body part. U.S Pat. The extent of adhesion of the layer of body putty remaining bonded to the metal substrate was also evaluated. A body putty was prepared from the following components: 100 grams body putty plus 2 grams 50% paste of benzoyl peroxide catalyst also referred to as dibenzoyl peroxide produced a gel time of about 4 to 6minutes.

In case of contact with eyes, rinse with plenty of water and seek medical advise. As it may seem logical, with more heat there will be less drying time and therefore less time for applying the mixture. Try to minimise air inlet by stirring the mixture, making sure thatthe colour obtained is uniform without colour streaks or differences. The remaining layer of body putty beyond the gapbonded firmly to the panel. 4,525,427 to Bayha, the disclosure of which is incorporated by reference herein.

The preferred automobile body putty comprises a thermosetting resin, preferably a blend of unsaturated polyester resin promoter, and a filler that is primarily talc. U.S. Pat. Remove this product from my favorite's list. Your cart will total 39 loyalty points that can be converted into a voucher of Rs. As usual, the different compatibilities between theputty and the type of material to be treated will be stated in thedata sheet. Generally, the drying time of the putty is between 20 and 30 minutes (5 minutes with short wave infrared) at a temperature close to 20C (it can vary depending on the type of putty). The etching solution of Example 1 was applied to the steel panels with a paint brush, allowed to remain thereon for 45 seconds and was then rinsed with distilled water.The panel was dried with a paper towel. However, rust and corrosion have increasingly become major problems for automobiles whose bodies are manufactured from mild steel. In accordance with the present invention, it has been found that improved adhesion of a polyester resin based putty to galvanized steel can be obtained by etching the surface of the galvanized steel with a solution ofa salt more electropositive than zinc and then applying the putty to the etched surface of the galvanized steel.
