Varnishes for glasscloth laminates, method of their production and laminates made therefrom |
| abstract |
he present invention relates to varnishes for use in the preparation of glasscloth laminates, methods of their production and laminates made therefrom. n The varnish is made by dissolving 100 parts of a TFP resin having a number average molecular weight of about 1000 and an oxygen content of about 8% in 60 to 65 parts of butan-2-one or isopropanol. 8 to 12 parts of hexamine are dissolved in a minimum quantity of a solvent comprising water and IMS in a ratio of about 3 : 5. The two solutions are thoroughly mixed and filtered to produce the varnish. n The varnish is used to prepare glasscloth laminates for use as printed circuit boards. |
