Is MEK rub test an effective method to confirm curing of two component coatings?


Comment from Charles S. Brown, (5/31/2016, 11:30 AM)

Yes, the MEK rub test can be an effective test for cure based on the coating being tested. The MEK rub test procedure can be found in ASTM D 4752.

what is the best controlled way to dry or cure waterborne coatings on metal substrates


Comment from Charles S. Brown, (6/7/2016, 2:21 PM)

The best controlled way to cure waterborne coatings is to use dehumidification equipment.


Comment from Antonio Leal, (7/25/2016, 12:07 PM)

Mr. Brown, with your permission, I would add the last two lines in the beautiful work presented. “Other issues that might cause drying or curing problems of a coating are: • Problems with the coating material sent from the manufacturer. • Use of the wrong thinner or contaminated thinner. • Moisture in some generic thinners compromising paint cure. • Coating film thickness. • Problems related to the type of surface to which the coating is applied, for example, wood absorbs paint whereas paint lays on top of steel. • Temperature considerations when mixing or storing coatings. • Ambient conditions present during dry and cure times.” • Paint application out the recommendation of the "dew point" • Mixing ratio of component A and B out of the recommendation.

Excellent article.

Also important for epoxy coatings, not to wait too long before overcoating. If the paint manufacturer's overcoating times are exceeded, abrading the paint coat may be necessary to achieve adequate adhesion of the next coat.

Very good article Charles. However, it's worth mentioning that on Moisture Cure (MC) coatings the curing process is different from a traditional 2 pack system with humidity required for curing, as these systems are getting more popular.


Comment from MARIANA HUHULEA, (8/3/2016, 3:46 AM)

Would like to emphasize Mr. Simon Wadsworth very good remark about keeping the overcoating intervals( minimum/ maximum), especially when it comes to excceding the maximum recommended one. Personally believe that once the coating system has lost the chemical bonding between its layers, performance in service encounters a major drop down. Most of Contractors consider abrading as a good -enough method for recoating out of the interval. Would suggest this topic as a future subject of a documented article and debate.
