工业涂装商优选的成熟粉末涂层技术

是否有一种粉末涂料,可以为 MDF 等工程木材带来与金属应用相似的强度、可靠性、美观性和成本效益?科思创为您带来答案,它就是 Uralac® Ultra

这种独特技术不仅是一种树脂,也是一种由不饱和聚酯、共交联剂和热引发剂组成的自由基固化技术。成果如何?打造出更安全、更可持续的粉末涂料,适用于 MDF 和工程木材,采用独特单层工艺,温度仅为 120-130℃,而非传统的 160-170℃。如今这种技术已被许多公司采用,为这些工业涂料制造商带来明显的竞争优势。

常见问题解答

How do we spray powder on standard 'non-conductive' MDF?

For application of the powder, moisture within the MDF is used for conductivity. A moisture content of 4-8% of total weight is sufficient to attract the powder.

Do we require special MDF for powder coating?

No special MDF is needed for powder coating – although there are differences between available qualities and types.  

We advise evaluating the type of MDF you intend to use before making your products.  

Further, we recommend a conditioned storage area to control the MDF's moisture content.

Is the oven I use for powder coating metal suitable for curing MDF too?

Most conventional curing ovens are convection ovens. Best results for MDF are reached with infrared radiation (IR) ovens.  

With IR ovens, the MDF's surface can be heated quickly to cure the powder coating, while its core stays relatively cool.  

With convection ovens, temperatures are often too high, or the MDF's core heats up too much because of the longer period needed to reach curing temperatures.
