3 Types of Metal Protection & Coatings

At Brighten, we offer three different types of coating for our metallic products, either for aesthetic reasons, such as colors, to function purposes to extend our signage’s durability. 
#1. Lacquer 

Lacquer is one of the most commonly used coating to seal and protect vulnerable metallic materials against the humid climates of our little island. Such metals includes aluminum and brass. It is also very easy in terms of application, as clear lacquer sprays are readily available off-the-shelf. We offer two types of lacquer coatings: off the shelf clear lacquer (1k), and 2k lacquer, which has increased resistance to weather and chemical exposure. 
#2. Anodise 

Anodising is a process specific to Aluminum, and is more of a chemical reaction as opposed to just a layer of coating. Making use of electricity currents in an acidic electrolytic solution, it forms a new layer on the aluminum’s surface that is much more resistant to the outside elements as compared to lacquer coatings. They usually come in either clear or black in terms of color. 
#3. Powder Coating 

This process involves both electricity and temperature. We use this process for clients who requires a coloured metal-based signage. It is more lasting than spray painting, and results in a thicker coat of paint. While anodising can only be applied to aluminum, this process can be applied to all materials, making it more versatile. One drawback is that chemical etching cannot be done along with powder coating on a single signage, as both processes cancels out one another. Our powder-coating signage is usually created with the use of stickers pasted onto the coated surface.
