Why is it important to use the correct sealer under waterborne basecoat versus solventborne basecoat?

Sealers are specifically developed to work with each type of basecoat to prevent lifting or wrinkling of the film. To avoid any potential lift windows, it is important to only use the sealer designed for that system. For example, when using ENVIROBASE® High Performance waterborne basecoat, you should use ECS sealers. If you’re a fan of solventborne basecoat like DELTRON® 2000 (DBC), DAS sealers should be your product of choice.

While it’s important to use all of the products within a given brand from start to finish, it’s especially important to stick with the correct sealer. Don’t take a chance that your paint job will wrinkle.

Pinchweld flanges that hold stationary glass require proper treatment during repairs. This insures proper bonding of the glass which helps to maintain the structural integrity of the vehicle. If the glass is not properly bonded to the flange, it can alter how the structure reacts in a collision or even during normal body flexing and driving.

A two-component epoxy primer, such as DPLF Epoxy Primer or DPLV 2.1 VOC Epoxy Primer, must be used on bare metal areas of pinchwelds when installing stationary glass using urethane repair materials. If metal repair or metal replacement is required, remove any corrosion and/or existing primer from the pinchweld flange to expose clean, bare metal. In order to restore the bonding strength of the area, epoxy primer must be applied and should be the only coating between the bare metal and the urethane adhesive.
