Abstract
A method of metallizing plastic parts, the method comprising the steps of: (a) etching a plastic part, by introducing the plastic part into an aqueous, acidic ozone etching solution, (b) metallizing the ozone etched, plastic part, and (c) heating the metallized part in an oven at an elevated temperature for a period of time. The ozone-etched and metallized plastic part after being heated in the oven exhibits increased peel strength and improved adhesion.

A method of metallizing a plastic part, the method comprising the steps of:
- a. etching a plastic part by introducing the plastic part into an aqueous, acidic ozone etching solution,
- b. metallizing the ozone-etched plastic part, and
- c. drying the ozone-etched and metallized plastic part in an oven at an elevated temperature for a period of time.
A method of metallizing a plastic part, the method comprising the steps of:
- a. etching a plastic part by introducing the plastic part into an aqueous, acidic ozone etching solution;
- b. metallizing the ozone-etched plastic part;
- and
- c. drying the ozone-etched and metallized plastic part in an oven at a temperature of between about 40 and about 90°° C. for about 30 to about 90 minutes to increase adhesion of the metallization layers on the ozone-etched plastic part,
- wherein the ozone-etched and metallized plastic part exhibits a peel strength of at least about 8.0 N/cm, as measured in accordance with ASTM Test Method B533-85(Reapproved 2019), Procedure A.
