Procedure

A coating composition is formed containing 2.5 grams Joncryl 587 (acrylated polyol from Johnson Polymers Inc.), 3.5 grams Cymel 303, 27 grams 1-methoxy-2-propanol (Dowanol PM), and 3.0 grams N,N′-diphenyl-N,N′-di[3-hydroxyphenyl]-terphenyl-diamine in a 1 ounce bottle. The components are mixed and the temperature is raised to about 40° C. until a complete solution is achieved. Next, 0.9 grams of p-toluenesulfonic acid/pyridine (8% acid/pyridine complex in 1-methoxy-2-propanol) (0.072 grams acid, 0.75% by weight) as catalyst is added.
