Study and Application of Coating Performance of Compact Waterborne B1B2 1K Varnish
In this paper,the coating performance of compact waterborne blb21k varnish is mainly introduced,the film-forming mechanism,film appearance performance,film abrasion resistance and aging performance of 1K Varnish and 2K varnish were compared and verified,the results show that there is a gap between the film performance of B1B2 process with 1K varnish process and that of B1B2 process with 2K varnish process,however,1K varnish has certain advantages in cost.
