The available anti-scratch coating for plastics are versatile products you can use for both short and long term surface protection. This will depend on the specific application requirement.
In any manufacturing process or application, time frame plays a pivotal role. It is for this reason that you can classify anti-scratch coating as either for short or long term applications.
Short term surface protection; these are anti-scratch coating formulated to protect a surface temporarily. Normally, it aims to protect the surface from any accident during manufacturing, packing or installation. Remember, such accidents may result in unnecessary repair and maintenance costs.
You will have to remove these surface protection later before using the product. These short term surface protection are available in form of films.
Long term surface protection; these anti-scratch coating remain on the surface of the products during use. At times, they may be referred to as permanent coating. These are the types of anti-scratch coating we shall discuss in this section.
There are several ways you can overcome polycarbonate surface protection challenges. These include:
Choose Anti-scratch Coating with Right Performance Specifications
There are different grades of anti-scratch coatings, depending on specific applications at hand. Well, you can use them both for indoor and outdoor applications. However, there are other things you need to consider.
Degree of hardness
To keep surface scratch free, the coating must fulfill certain requirements – degree of hardness. Of course, you can verify this using various hardness tests such as Taber, steel wool, eraser and tumble test.
The degree of hardness of all anti-scratch coating for plastics are categorized as:
- >1H for general use
- >3H for upgraded anti-scratch coating
- Between 8H and 9H for superior anti-scratch coating
Of course, there is the thermoformable and an optical scratch coating too.
With all these options available, you can easily choose the right coating for any plastic surface.
The degree of hardness of an anti-scratch coating plays a pivotal role here. Therefore, you need to understand the requirements of the work at hand based on the degree of hardness required.
Consider the right ingredients to consolidate with anti-scratch coating for plastics
We all acknowledge the fact that, anti-scratch coating is specifically formulated to reduce chances of scratches on polycarbonate or acrylic sheets. However, this is not the only problem that you have to deal with.
Assuming you work in a manufacturing industry, which environmental factors can impair vision?
For a fact, there are quite a number. That is, you will be subjected to humid conditions, ultraviolet radiations, chemicals, etc. All these will affect polycarbonate face shield in one way or the other.
It is for this reason that companies not only focus on reducing scratches, but also, the ability to consolidate it with other technologies. Such surfaces are considered superior and are highly recommend for all applications.
The good news is, you can consolidate this anti-scratch coating for plastics with UV resistant, anti-glare and anti-graffiti.
However, for anti-fog coating, the situation is slightly different. Anti-fog coating will be on one side of the polycarbonate sheet while anti-scratch coating will be on the opposite side.
Choose the right technology for anti-scratch coating process
Technology plays an important role in anti-scratch coating industry. You need to understand that a plastic coating will only bind successfully on a given surface if you adopt a reliable technology for the process.
Here is where most people go wrong. Don’t purchase a polycarbonate face shield simply because it has an anti-scratch coating on its surface. In most cases, you may purchase it today, only to fail after a few days.
First, you should consider the coating process. There are only two technologies you can trust when it comes to this and these include:
With these, you can achieve a uniform surface thickness. The layer of the anti-scratch coating is permanent and does not peel off.
Moreover, the technology in the curing process is also important. Again, for this process, the following technologies have proven to be reliable:
- UV curing
- Thermo curing
When you purchase a polycarbonate face shield that feature any of these technologies, you will be guaranteed of a scratch free surface. Thus, you will not be exposed to any danger.
Adopt a good care and maintenance procedure
All polycarbonate face shields with plastic coating require specialized care and maintenance process. That is, you must follow the recommended cleaning and care procedure that will ensure the coating does not peel off. It is for this reason that manufacturers recommend cleaning detergents and process.
Specific requirements (degree of hardness), technology and cleaning procedures are fundamental aspects to consider in this process. When you put all these into consideration, there is a high chance that you will get a quality anti-scratch coating for plastic face shield.
