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.

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.
