Procedure

In order to prepare the test coating, 100 grams of the above oligomer were mixed with 0.1 gram of T-12 tin catalyst, and 20 grams of EEP solvent. A second component was prepared from 126.4 grams of isocyanate multifunctional oligomer biurets formed by the reaction product between hexamethylene diisocyanate and water and 20 g of EEP solvent. Three mil wet films were cast from the mixed components which dried hard in two hours and had a Sward hardness of 10 in 24 hours.
