PPG Industries' packaging coatings business has announced that it will feature HOBA PURAIR coating, an innovative Bisphenol A non-intent (BPA-NI, or with no BPA intentionally added) powder liner for the internal protection of aluminium aerosol cans, during the Aerosol and Dispensing Forum in Paris, Feb. 3-4. The product from PPG’s brand HOBA Purair contains no solvent. It helps canmakers meet environmental and sustainable technology goals such as reducing volatile organic compound (VOC) emissions and providing high utilization and recycling capability.

Powder coatings are just emerging into limited use for monobloc aerosol packaging, according to Robyn McMillan, PPG global segment manager for monobloc aerosol and tube coatings.

“Powder coatings can play a key role in aerosol packaging going forward by satisfying regulatory and environmental concerns, especially regarding the use of solvents,” she said. “With the innovative HOBA Purair internal powder liner, PPG offers a high-performance sustainable solution that helps maximize product utilization while minimizing environmental impact.”

McMillan added that the PPG liner, HOBA Purair is made with select raw materials to meet regulations as well as canmakers’ and brand owners’ requirements. PPG Packaging Coatings developed the HOBA Purair powder liner in collaboration with PPG’s industrial coatings business – an established leader in powder coatings for automotive, transportation, appliance, office furniture, building and architectural applications. The product offers good smoothness at low thicknesses as well as excellent coating flexibility, and it can be used in most existing application processes.

The HOBA Purair internal powder liner is the latest addition to PPG’s complete range of newgeneration monobloc aerosol and tube coatings designed to meet regulatory requirements while offering high performance and a wide range of filling compatibility. The line also includes HOBA MAX (PPG8900 series), HOBA VCL and HOBA VGL (PPG2845 series) coatings.
