Masking tape dots are polyester film dots used to mask surface areas during processes such as electroplating and powder coating. These semi-transparent dots adhere to many different materials and are easily removable. Although many masking dots look the same, they come in various types that can be used for different projects. In this blog, we’ll explore some of the different types of masking dots as well as their features.
High temperature masking discs
High temperature masking tape dots are rubber-based adhesive dots that are resistant to temperatures up to 160°C. Their adhesive qualities mean that they are simple and easy to remove without leaving any residue on the protected material. This masking product is ideal for power coating and is often used to cover the hubs on alloy wheels. These discs are great for saving time and giving the perfect finish during any high temperature project.
Polyimide masking tape dots
These masking discs are constructed from polyimide and utilise a silicone adhesive for easy removal. Polyimide masking dots can also be used at high temperatures of up to 260°C, making them good for masking during powder coating, anodising, and shot blasting projects. Their versatility means that they can be made into any shape or size to mask even the smallest details. Overall, polyimide masking tape dots are a strong masking solution for any high temperature applications.
Silicone masking dots
This masking product is multi-purpose and can withstand high temperatures up to 180°C due to its silicone adhesive. The silicone material bonds quickly to any surface, and its heavy-duty properties eliminate the danger of any punctures or tears. These making tape dots are great for masking surfaces with irregular sizes and profiles for precision masking. This precision prevents bleeding and allows for a neat finish.
Crepe masking discs
These masking tape dots are made from smooth crepe paper with a rubber adhesive. They are pressure sensitive discs that can be used for temporary or permanent applications. Crepe masking discs can withstand high temperatures of up to 163°C but are not recommended for outdoor use, so are ideal for powder coating or high temperature masking projects. They are pliable and therefore can mask surfaces of different shapes and sizes.
