配方類型： COATINGS
配方說明： Pre-Preg Varnish
配方組成： Dicyandiamide/4
Acetone- To desired viscosity
Dimethyl Formamide/15
"Dow" Epoxy Resins/100
Dowanol EM/15
配制方法： Blend the DMF, "Dowanol" and dicy. and agitate to obtain solution.
Warm the mix to 110-130F. The "Dowanol"/DMF ratio is flexible and can be altered if desired. This step is important as it completes solution of the dicy. and insures against later precipitation of dicy. from the varnish. After allowing the dicy. solution to return to room temperature, blend the resin solution with it and agitate thoroughly.
