Waterborne Adhesion Promoter

Waterborne Chlorinated Polyolefin Adhesion Promoters (Ad-Pro's)

The first ever waterborne chlorinated polyolefin adhesion promoters (Ad-Pro's) were developed, patented, and introduced to market over 20 years ago by A-Line Products. These ad-pro products are used to promote adhesion over thermoplastic polyolefin (TPO) and polypropylene (PP) substrates prior to the application of subsequent coatings. Since the introduction, millions of automotive TPO and PP interior and exterior moldings such as airbags covers, fascias, cladding and bodyside trim parts have utilized these waterborne coatings. Waterborne adhesion promoters are available with conductive or non-conductive properties.

AL-1120C CONDUCTIVE WATERBORNE ADHESION PROMOTER

AL-1120C is a unique conductive waterborne adhesion promoter for thermoplastic polyolefin (TPO) and polypropylene (PP) substrates. It is used in flexible automotive exterior trim such as fascia, cladding and body side moldings. These substrates are inherently difficult to paint due to their polarity, low surface energy and amorphous composition. AL-1120C is formulated with a chlorinated polyolefin (CPO) as well as conductive resins. These conductive resins provide a continuous conductive surface once the CPO film has coalesced. This enables subsequent paint layers to be applied by conventional electrostatic spray equipment and therefore enhances transfer efficiency. Color-keyed and clear AL-1120C is available without the conductive properties for use in polyurethane foams and inks.

APPLICATION

AL-1120C should be applied without any further dilution. Once applied, force dry for 5-10 minutes at >180o F / 82o C before applying any basecoat or subsequent coatings. In applications where a forced air drying system is not in place, accelerated drying can be achieved through the use of an infrared heat or a dehumidification system. It is recommended that 90% of the water be removed from the primer film before any subsequent coating is applied. Plant conditions, line speed, oven type and part surface temperatures will determine the actual time or heat required to remove 90% of the water. Maximum adhesion levels are obtained after a 5 minute bake at 250o F / 121o C.

Service Primer: When used as a service primer, bake 5 minutes at 250o F part temperature
