lower values being better again as a comparison a rosin dosage of 14 lb ton gave a laew value of about 5 8 for asa alone the laew was significantly better than the rosin only value and improved decreased from about 1 8 to about 0 6 as the dosage increased from 2 to 4 lb ton for a combination of asa with a constant 7 lb ton of rosin the laew was also good dropping from about 2 1 to 1 8 as the asa dosage increased from 2 to 4 lb ton thus even 2 lb ton asa with 7 lb ton rosin 9 lb ton total gave a laew much better than provided by 14 lb ton rosin for akd alone the laew of 8 5 at a dosage of 2 lb ton was not as good as the rosin value at 14 lb ton but laew values of about 3 to almost zero were achieved as the dosage of akd dropped to 3 and 4 lb ton for a combination of rosin with a constant 2 lb ton of akd the laew varied from about 6 4 to about 7 as the rosin dosage varied from 4 to 6 lb ton fig4 illustrates the effect of sizing agents at various dosages on the 24 hour lactic acid edge wick 24 laew lower values being better again.
