There aren’t many industries more global than the automotive industry. For our coating customers, maintaining quality and consistency across geographies, while also managing costs and meeting differing consumer demands and regulations, is a tough challenge. But it’s a road that the global resins team at Covestro is well equipped to help you travel. We have the technology toolbox – from waterborne to powder and two-component resins. We have the people. We know the regulations inside out. And we understand the materials – whether traditional metal or the growing use of plastic - for new cars and parts or refinish.
In fact, at Covestro, we even have a dedicated automotive plastics business. Rest assured that, in addition to our customers, we work closely with these colleagues to continue maximizing our knowledge of materials science in order to drive innovation – for example, through a new generation of waterborne resins for vehicle base coats.
Our resins for powder-coated metal can be found in more intricate consumer applications than you’d think. A lot more applications:
Vending machines, electrical fans, hot water heaters, freezer cabinets, refrigerator liners, microwave cavities, washing machine tops and lids, gas cylinders, bicycles, cookware and grills, lawnmowers, sports equipment, fire extinguishers, light fixtures, transformers, electrical boxes, waste bins – the list is growing every day.
Advancements in everything from mobiles to electric cars means developing durable and resilient new coatings for increasingly higher-powered batteries, as well as charging stations. These next-generation products require next-generation coatings – and resins – that are capable of working with new substrates such as carbon fiber reinforced plastic (CFRP) and aluminum.
Equally as important is the fact that the coatings on these often intricate and highly delicate electronic parts will need to be cured at lower temperatures.
This is just one of the challenges that our technical team is exploring, and we need to solve it fast. For evidence of how fast this battery revolution is moving, we need look no further than the innovation for extending battery life that could revolutionize our society.
At Covestro we produce powder coating resins that meet the strict requirements for food contact applications.
Our Uralac® F-grade resins are produced to GMP (Good Manufacturing Practice) standards for use in consumer applications that come into contact with food and drinking water – like refrigerator racks, food shelving, water pumps and boilers.
Specifically, they fulfil the requirements of the European regulations EC No 1935/2004 & EC No 2023/2006, which state that food contact articles must be safe and may not release substances in quantities that could endanger human health or deteriorate the taste and odor of the food.
Normally, extraction and/or migration tests are needed to determine the amount of organic material extracted from any coating – and this in turn very much depends on the coating ingredients being used (of which the resin is absolutely key).
For all independently conducted testing procedures we will provide our resins (under appropriate non-disclosure agreements) to the relevant institutes – thus enabling our customers to create quality coatings that meet the highest safety standards.
"Increasingly, our customers are finding that powder coating technology for metal delivers significant advantages in the domestic appliance segment.
In fact, our powder coating resins for kitchen appliances and white goods in particular are more economical and easy to coat, while delivering excellent durability and resistance to chemical and detergents.
Our resins are available in various polyester-epoxy hybrid grades and also deliver outstanding aesthetics including special-effect textures where dust collected on the surface is less visible – which means less cleaning.
Good for the consumer, good for the planet, and good for the coating industry."
