Water Based Automotive Paint Problems
Also known as edge mapping this paint problem results from solvents in topcoats penetrating through areas of the undercoats.
Water based automotive paint problems. These are becoming the standard for collision painting because they are quicker to use and easier to blend. With new rules regulating the use of volatile organic compounds vocs in spray paint now in effect auto body shop operators are under pressure to quickly convert from traditional solvent based paints to newer water based ones. The paint itself was ok. Water based paint is just as durable you can get all sorts of different lacquers.
Much more development and testing have been done since. Sometimes solvent based paints will develop bubbles as the gases in the paint are released well after the paint job. If air is kept moving across. Because they are water based waterborne paints go on in much thinner layers than traditional solvent based paint leaving a smooth bright and even finish.
In fact the collision industry advanced further in the 2000 s and developed water based and waterborne finishes. Ferre tells us that particular paint lifting problem was due to incompatibility between the paint and the primer. I ve got the undercoat looking really good but as soon as i try to put on the satin top coat it just turns into a nightmare of brush strokes. I can paint with oil based no problem but this is a whole different kettle of fish or paint.
To avoid this make certain to use a primer surfacer that is water based two component or another sealer to create a good barrier layer. It looks like a wrinkling around an area that has been repaired. As the earlier description of waterborne paint implies these new paints require increased airflow to remove the water from the paint far beyond the standard solvent based paints. Two pack paint will be around for a good few years yet as it is primarily what commercial vehicles are painted in.
Water based car paints are now relatively common in professional bodyshops having been used several years earlier by most manufacturers. Water soluble solid colours and basecoats are now commonly used by paintshops largely because of stricter regulations regarding voc solvent content in traditional car paints. While this is a bit of a hardship on many paint shop operations there are a number of advantages the new coatings offering that should help small businesses justify the cost of making the transition.
