PPG has introduced new products including conductive and non-conductive urethane primers that perform efficiently on most types of plastic used in some key applications.

The company also unveiled a new urethane surfacer, which it added to its Delfleet Evolution product line.
The company’s industrial coatings business announced the launch of Spectracron SPU conductive and non-conductive urethane primers, the first products of their kind to be engineered for application over multiple plastic substrates, such as Metton LMR (liquid moulding resin) and sheet-moulded composite (SMC) plastics. 

Scott Laney, PPG liquid products manager, industrial coatings, said Spectracron SPU is a major advance in primer technology because it enables heavy-duty equipment (HDE) and automotive component manufacturers to prime parts made from multiple plastic substrates with a single product. 

“OEMs and their tier suppliers traditionally have prepped multi-plastic parts with multiple primers, adding time and complication to the production process and increasing the potential for quality problems,” Laney explained. “PPG’s new Spectracron SPU urethane primers deliver excellent performance on most types of plastic used in the heavy-duty equipment and transportation industries.” In addition to being compatible with a wide range of plastic substrates, Spectracron SPU conductive primer reduces wet-on-wet times to three minutes, allowing manufacturers to finish parts several minutes sooner than is possible with other conductive plastic primers. 

Spectracron SPU non-conductive and the PACCAR-approved conductive primer are formulated to harmonise with PPG’s OEM-approved two-component topcoat, giving manufacturers the option to streamline their inventories by stocking an integrated primer and coatings system from a single supplier. 

Founded in 1883, PPG has its global headquarters in Pittsburgh and operates in more than 70 countries around the world. Reported net sales in 2015 were $15.3 billion.

Meanwhile, PPG’s commercial coatings group has added F4932 2.1 VOC (volatile organic compound) Urethane Surfacer to the Delfleet  Evolution product line. 

F4932 is a high-build grey urethane surfacer with excellent fill properties. It offers characteristics designed to enhance and maximise shop productivity. The new surfacer delivers high build and sands easily, drying fast often in as little as one hour. F4932 is also chromate-free. 

PPG’s commercial coatings group offers a full range of coating technologies for the commercial transportation and light industrial markets, such as polyurethanes, alkyds, epoxies, polyurea, waterborne, pretreatment chemicals and powder coatings.
