Reduced drying time with water based coating replacement Quakercoat® 856 Green
CHALLENGES
A tube and pipe manufacturer wanted to replace the solvent based paint coating that was used on their couplings inserts due to the hazards associated with that coating including fumes and am- mability risks. By switching to a water based technology, the company wanted to:
Reduce workers’ exposure to solvent health hazards
Bene t from the environmen- tal friendly properties
Reduce drying time
The replacement coating had to be evaluated under the current handling and drying process con- ditions to determine if it could deliver a similar performance compared to the existing coating.
THE SOLUTION
Quaker Chemical Corporation (“Quaker”) selected the water based coating, QUAKERCOAT® 856 GREEN for evaluation. The formula was customized for the coating process to match the color tone, appearance, and exibility ; and
to work with the limitations of the existing equipment. Additionally, the product properties were mod- i ed to be able to comply with downstream process requirements including the forming press.
Application tests were performed to ne tune the properties of the coating with the goal of achiev- ing a faster drying time than the 45 minutes needed with the solvent based coating. Two drying approaches were tested with the QUAKERCOAT® 856 GREEN provid- ing the following results:
Oven assisted drying at 40° C = 10 minutes
Ambient air drying with venti- lation = 15 minutes
The switch to QUAKERCOAT® 856 GREEN resulted in:
Reduced drying time to 15 minutes which was 66% less versus the solvent drying time
Similar color nish as the solvent coating with minimal differences in brightness
Improved coating appearance with no foaming and no runoff
Less fumes as reported by line worker feedback
Reduced insurance costs due to the elimination of the hazards involved with low ash point coatings
Approved coating exibility performance as tested in the pressing application
THE PRODUCT
QUAKERCOAT® 856 GREEN is a non- ammable, water based paint coating with low VOC emissions. It is applied without diluting or adjusting viscosity. QUAKERCOAT® 856 GREEN provides uniform cov- erage during application and excellent durability and perfor- mance. In addition, it has high exibility for press conditions after painting.
