What are temporary masking materials or solder masks ?
Temporary masking materials are used in various industries, including automotive, aerospace, and electronics, to protect surfaces from damage during processing or painting. They are applied to act as temporary barriers, that are subsequently removed from the completed component after processing. As a result, the ability to be removed without leaving any residue on the surface is one of the most important factors to choose the masking materials.
Temporary masking goes beyond the intended purpose. Discover more about potential application of temporary masking material and how it help in your manufacturing process.
Common types of masking materials:
Temporary masking materials are used in a variety of manufacturing conditions, such as high temperature PCB soldering, or conformal coating process. Considerations for selecting temporary masking materials can be based on their resistance to temperature, chemicals, stickiness or curing time, etc. Therefore, masking materials are available in many types, each type has its own unique features to meet those needs.

Masking Tape: Masking tapes are made of thin paper or plastic film with an adhesive backing. Masking tapes come in various widths and adhesive strengths, making them suitable for different applications.
UV Masking: UV masking materials are fast curing, solvent-free resins designed for manual or automated masking of printed circuit boards. They are applied prior to wave or reflow soldering operations, or conformal coating.
Liquid Masking: Liquid masking materials, also known as peelable coatings, are applied to a surface and allowed to dry to form a solid layer that can be peeled off after use. They are often used to protect surfaces from chemicals or abrasion during processing.
Water Soluble Masking: Water soluble masking materials are typically used in industrial settings to protect surfaces from abrasive blasting, chemical processing, or painting. They are often applied using a spray gun or brush and can be easily removed with water after use.
Hot Melt Masking: Hot melt masking materials are applied to surfaces using a hot melt glue gun. They are commonly used in powder coating applications, where they are used to mask off areas that should not be coated. Hot melt masking materials are heat resistant and can be easily removed after use.
Latex Rubber Masking: Latex rubber masking materials are commonly used in the automotive industry to protect surfaces during the painting process. Latex rubber masking materials are resistant to solvents and chemicals and can be used in high-temperature applications.

Disadvantages |
|
Masking tape |
– Convenient and fast – Easy to apply and remove from the surface without marks or damage – Highly durable helping to keep surfaces protected for a long time |
– Not all masking tapes are heat or chemical resistant, so it’s important to choose the right one for your particular application’s requirements – It may lose its stickiness if exposed to excessive heat or left in a humid environment |
|
UV masking |
– Highly precise coverage areas can be generated and customized as product requirements – Fast and efficient, effectively reduce production time and labor costs – Easy to remove without marks or damage on the surface |
– Equipment investment is required (UV light fixtures) to cure the coating – UV masking cannot be used to protect areas that are too large or have complex shapes
|
|
Liquid masking |
– Highly precise coverage areas can be generated and can be customized to product requirements – Easy to use and can be removed easily – No damage to the surface and can be used on a variety of surfaces |
– The drying time required to achieve strength depends on many factors such as humidity, temperature and thickness of the liquid masking layer – Cannot be used to create coverage areas that are too large or have complex shapes |
|
Water soblube masking |
– Easy to use and can be cleaned with water easily without harming the surface of the product – Can be used to create highly accurate coverage areas and can be customized to product requirements |
– Cannot be used to create coverage areas that are too large or have complex shapes
|
|
Hot melt masking |
– Easy to use and can be generated with a wide range of coverage coatings with high precision – Can withstand high temperatures and is not affected by chemicals. |
– Cannot be removed with water, and its removal may require the use of strong solvents – The strength of the adhesive layer can be affected by humidity |
|
Latex and rubber masking |
-Protects delicate components -Ideal for situations where a thick coat of mask is required |
– Cannot withstand strong chemical substances – The humidity can affect curing time |
