Many aluminum profile merchants often encounter situations where their products need to be protected by coatings, but they often don’t know how to choose the product, powder coating? Or PVDF paint? This article will introduce in detail and tell you how to choose
What is pvdf coating?
PVDF coating, also known as fluorocarbon coating, is a common liquid coating that is widely used in the surface treatment of aluminum plates and aluminum profiles. PVDF paint is often the first choice for aluminum because of its excellent weather resistance. PVDF coating can and can only be used on aluminum profiles or steel structures.
There are several types of pvdf coating?
PVDF paint is divided into two types according to the curing type, one is self-drying type and the other is baking type. Self-drying type means that it does not need to be placed in a high-temperature oven after electrostatic spraying, and it will cure itself after standing for a period of time, while baking type is the same as powder coating, which is placed in a high-temperature oven after electrostatic spraying and cured at 200 degrees.
Why is aluminum profile suitable for PVDF spraying?
Aluminum is suitable for spraying. On the one hand, it is because of its use. Aluminum is often used as an indispensable raw material for outdoor buildings. Whether it is building doors and windows, or bridges and structural parts, aluminum is an indispensable raw material. Most of these materials require strong weather resistance, and PVDF’s high weather resistance can meet these needs. KGE PVDF Coating meets AAMA2605 and has a maximum weather resistance of 25 years.So compared to powder coating, PVDF is a better choice for aluminum surface treatment
How is PVDF coating applied to aluminum?
Aluminum profile spraying generally goes through three layers of process, the first layer is “primer” also known as Primer, the second layer is “top coat” also known as Top Coat, and the third layer is “clear coat” also known as Clear Coat. We usually call the three-layer process three-layer coating, and only the first two layers are called two-layer coating.
In many cases, the large-scale use of fluorocarbon paint on aluminum is determined by the actual needs of aluminum use. Our pvdf coating can actually withstand weathering for 25 years, which can meet most usage scenarios. Welcome to consult us!
