Fully understanding MDF powder coating

MDF powder coating

Powder coating on metal surfaces is well established, very stable and has good level control. To understand why MDF powder coating and metal surface powder coatings are so different, it is necessary to understand the inherent properties of MDF. It is generally believed that the main difference between metal and MDF is electrical conductivity. This may be true in terms of absolute conductivity values; however, it is not the most important factor for MDF powder coatings Typically, MDF powder coatingRead More …

What is Epoxy Coatings

Epoxy Coatings

Epoxy-based coatings can be two-component systems (also named two part epoxy coating) or used as a powder coating. The two part epoxy coatings are used for high performance systems on metal substrate. They are a good alternative to powder coating formulations in industrial and automotive applications thanks to their low volatility and compatibility with waterborne formulations. Epoxy powder coating is widely used for metal coating in “white goods” applications like heaters and large appliances panels. Epoxy coating are also widely usedRead More …

Types of Matting Additives Used In Powder Coating or Paint

Types of Matting Additives Used In Powder Coating or Paint

There are four Types of Matting additives Used In Powder Coating or Paint. Silicas In the broad field of obtainable silicas for matting there are two groups which differ in terms of their production process. One is the hydro-thermal process, which produces silicas with a relatively soft morphology. By using the silica-gel process products can be obtained which have a harder morphology. Both processes are capable of producing standard silica and after treated products. After treatment means that the silicaRead More …

Filiform corrosion is appearing mostly on aluminum

Filiform corrosion

Filiform corrosion is special kind of corrosion appearing mostly on aluminum. The phenomenon resembles a worm creeping under the coating, always starting from a cut edge or a damage in the layer. Filiform corrosion develops easily when the coated object is exposed to salt in combination with temperatures 30/40°C and relative humidity 60-90%. This problem is therefore limited to coastal areas and linked with unfortunate combination of aluminum alloys and pre-treatment. To minimize filiform corrosions it is advised to ensureRead More …
