How to choose right and cost-effective high temperature masking tape for powder coating? here, TOPKING introduces types of powder coating masking tape and its corresponding features, so you can have a clear ideas on how to choose high temp powder coating masking tape.
What’s Powder Coating?
Powder coating is now a popular finishing process that is to spray powder coating to surface of the work piece by powder spraying equipment, usually electrostatic spraying machines. Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the work piece to form a powder coating.
After high temperature baking and leveling curing, powder coating came into the final coating of the different kinds of effects. The spraying effective of powder coating is better than traditional liquid spraying in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, and so on. Therefore, powder coating is now widely applied in many industries, such as automotive, electronics, home decoration and more.
Why Powder Coating Requires Heat Resistant Masking Tape?
Powder coating process, however, involves high temperature heating operation (typically at temperatures ranging from 190°C to 232°C) that may have bad impacts on some areas if not protected. Then, powder coating requires high quality heat resistant masking tapes to deal with high temperature and provide enough protection. Here are some reasons why powder coating requires high temperature masking tapes.
- High Temperature Curing: Heat resistant masking tape can’t melting, shrinking, and leaving residues in the powder coating curing process.
- Optional Protection: High temperature masking tape can provide protections for areas that don’t need powdering coating, like threaded sections, brand labels, specific design elements or others. In addition,some of the materials being powder coated might be sensitive to heat or the chemicals in the powder, then high temperature masking tape can effectively prevent damages or degradations that might happen during powder coating process.
- No Adhesive Residues: When powder coating curing process finished, it is necessary to remove masking tapes since it may have effects on functions and appearance of items. High temperature masking tape can be easily removed and leaves no residues.
Therefore, choosing a suitable high temperature masking tape is necessary for powder coating.
How to Choose High Temperature Masking Tape for Powder Coating?
There are various high temperature adhesive tapes that are suitable for powder coating masking in the market You can choose the most suitable one based on your specific needs and budget. Here we mainly introduce some of the hot sale and popular heat resistant masking tape for powder coating
Polyester Adhesive Tape
It is also called powder coating green masking tape. lts heat resistance is about 220°C. lt is generally used for the masking of threaded studs, plugs, holes or sections that don’t require coating.
Polyimide Adhesive Tape
lt is Kapton tape with higher heat resistance, generally about 260°C. in most cases, it will be used for the powder coating of electronics, especially materials that is sensitive and requires high temp masking.
Crepe Paper Masking Tape
lt is the most cost effective high temp masking tape for powder coating and its heat resistance is about 180°C. So, it is more suitable for powder coating that don’t have higher temperature.
PTFE Teflon Tape
lt is featured with excellent chemical and heat resistance. lts temperature resistance is about 260°C. Therefore, if there require chemical resistance in powder coating, it is a good choice.
Glass Cloth Tape
lts woven fiberglass cloth offers excellent high tensile strength, and its temperature resistance can reach up to 260°C. So, if the powder coating process requires high mechanical strength choose it.
