Process for the after-treatment of phosphate-coatings |
| abstract |
A PROCESS FOR THE AFTER-TREATMENT OF PHOSPHATIZED METAL ARTICLES, WHICH PROCESS COMPRISES TREATING THE PHOSPHATIZED SURFACE OF THE METAL ARTICLE WITH AQUEOUS SOLUTION CONTAINING AN ALKALI METAL SALT OF A NOVOLAC PHENOL-FORMALDEHYDE RESIN HAVING A MOLECULAR WEIGTH OF FROM ABOUT 300 TO ABOUT 5,000, AND HEATING THE TREATED ARTICLE AT A TEMPERATURE OF AT LEAST ABOUT 190*C. IN THE PRESENCE OF AN OXYGEN-CONTAINING ATMOSPHERE. THE ARTICLES SO TREATED ARE RENDERED EXCEPTIONALLY RESISTANT TO CORROSION AND TO UNDERCUTTING WHEN COATED WITH FINAL FINISH COATINGS. |
