PPG PR-182 Clear is a water-based, VOC-compliant adhesion promoter that enhances the coupling of polysulfide sealants to a wide variety of substrates. It is formulated as a safer alternative to organic solvent-based products: non-flammable, non-toxic and does not soften finishes. It is a one-part compound applied by brush or clean gauze and dries at room temperature in approximately 30 minutes.
