As a supplier of non-stick coating services to some of the biggest brands within the UK food industry, having a high-quality, food grade solution to offer is of paramount importance to Product Release.
What does food grade mean?
The term food grade can be applied to anything that is used within the processing, manufacturing or storage of food, essentially anything that comes into contact with food goods could and should meet food grade specifications. This means that for anything to be classed as food grade it needs to be non-toxic and ensure that it has no impact on whether the food products it comes into contact with are fit for consumption.
What food grade coating do we use?
We focused the development of our food grade coating in one area to produce a robust solution that is suitable for numerous situations. Our PR235W is a two-coat fluoropolymer coating, which consists of one pigmented primer layer and then an un-pigmented fluoropolymer topcoat layer. It has been successfully utilised in a wide range of coating applications including baking trays for morning goods, biscuits and Yorkshire puddings, as well as for a number of production machinery applications.
To ensure that this solution meets the requirements to be classed as food grade, the products that make up this coating are all on the FDA positive list for food applications, Regulation 21 CFR 177.1550 and 21 CFR 177.2440. As well as this they also comply with “the materials and articles intended to come into contact with food regulations (EC 1935/2004).
What are the other properties of PR235W?
PR235W is designed to impart maximum release/non-stick properties and also has excellent low friction properties to further improve usage.
It also provides strong heat resistance, allowing products and equipment coated with this solution that are in continuous use to be utilised in temperatures ranging from -40°C to 260°C, whereas temperatures of up to 290°C can be intermittently used.
For chemical resistance, this coating option is chemically inert in its pore free state and, while it is normally unaffected within chemical environments, we do advise on consulting with our technical department if this is your requirement.
Similarly, PR235W provide a fair amount of wear resistance to coated goods, though we do have superior solutions to this if minimising wear is a key goal.
