Experimental Objective<\/strong><\/strong><\/h2>\n\n\n\n

To compare the solubility of novel solvents EEP and MMP versus the traditional solvent PMA in blended\u00a0solvent systems for polyaspartic polyurea coatings, and to evaluate the effect of EEP and MMP on the appearance of the paint film.<\/p>\n\n\n\n

Notes:
1. Requires grinding with a three-roll mill, 30 min\/time, grind 3 times, cooling with tap water between intervals;
2. During solvent batching, only add 20.3g of PMA\/EEP\/MMP solvent initially, add the rest after viscosity measurement.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

1.2 Viscosity Change Curves Measurement<\/strong><\/p>\n\n\n\n

Blended\u00a0solvents of EEP, MMP, and PMA were used to dissolve the polyaspartic polyurea coating (Component A) at proportions of 5%, 10%, 15%, 20%, 25%, and 30%. Viscosity change curves were measured to analyze the solubility of the blended\u00a0solvents for the polyaspartic polyurea coating. (Note: Since the evaluation system is paint, viscosity was measured using Cup-4 viscosity at 24\u00b0C\u201325\u00b0C.)<\/p>\n\n\n\n
