In the fields of construction and industry, masking tape, as a commonly used product, is very popular because of its better heat resistance compared with packaging tape and its significant advantages such as no residue after tearing. Today, let’s discuss in depth about masking tape. Relevant knowledge of tape.
What Is Masking Tape?
It is a special sealing tape, which is mainly used to cover surfaces that do not need to be painted or protected in scenarios such as automobile painting and home decoration. Therefore, it is often called painter’s tape.
When Was Masking Tape Invented?
In the mid-1920s, the workshop at that time used kraft paper as the spray shielding material. This traditional process had significant defects: First, the texture of kraft paper was rough, and the thickness was uneven, making it difficult to fit the complex curved surface structure of automobiles, and the sealing often occurred. The problem of paint mist penetration is caused by lax sealing. Secondly, kraft paper adhesive produces stubborn residue when peeling off, which requires additional manual cleaning. Facing the pain point of this industry, engineer Richard Gurley Drew chose cotton substrate instead of coarse kraft paper, developed a synthetic rubber adhesive with better pressure sensitivity, and made the width of the tape accurate to 3 inches. This new type of masking tape can not only perfectly fit the curved surface contour of the automobile, but also its moderate peel strength ensures the sealing performance during spraying.
What Is Masking Tape Made Of?
The masking tape consists of two parts:
Backing material: This is the basic part of the masking tape and provides the physical properties of the tape structure. Common backing materials include plastic film, paper, fabric, etc. Different backing materials have different characteristics. Plastic film backing materials usually have good water resistance and chemical resistance, while paper backing materials are relatively more environmentally friendly and lower cost.
Adhesive: It is a very important part of the structure of the masking tape. It provides the ability to adhere to the adhered surface, allowing the tape to be firmly adhered to the object that needs to be masked. There are many types of adhesives, and different adhesives are suitable for different application scenarios and material surfaces.
Types Of Masking Tape
Masking tape is divided into the following common types according to the material, and each type has its own unique advantages.
Washi Paper Masking Tape
Based on natural and degradable environmentally friendly paper, the texture is soft and light, and can perfectly fit curved surfaces and complex surfaces; The medium and low viscosity design ensures that there is no residual glue and no damage to objects when removed. It has good air permeability and is suitable for watercolor, acrylic and other paint creations. It is both practical and economical, and is an ideal choice for artistic creation and handicraft enthusiasts.
Polyvinyl chloride (PVC) material has strong weather resistance, stretch resistance and is not easy to deform, so it is suitable for humid environment or outdoor construction.
Polyester (PET) substrate is resistant to chemical corrosion and ultraviolet aging, and can withstand high temperatures from 180 ℃ to 250 ℃.
Acrylic has high viscosity, ultraviolet resistance, can adhere to rough or high-density surfaces and is not easy to warp.
Cloth Fabric Masking Tape
Cloth-based masking tape is made with high-strength fiber cloth as the base material, combined with a high-quality pressure-sensitive adhesive layer, and is specially designed for industrial scenarios that require high temperature resistance, tear resistance and strong adhesion.
Specially designed for large-area shielding work, it uses PET or PVC temperature-resistant polymer materials to cover the surface to be protected and resist the erosion of chemicals such as paints, solvents, acids, and alkalis. It is suitable for a variety of industrial coating scenarios.
Liquid Masking Tape
Liquid masking tape supports any shape masking and perfectly fits complex gaps. After drying, it forms a water-resistant and chemical-resistant protective layer.
The above are classified by material, and according to characteristics, they are divided into high-viscosity masking tape, medium-viscosity, low-viscosity masking tape, general-purpose masking tape, high-temperature masking tape, double-sided masking tape, and other types.
Masking tape sizes
The sizes and specifications of masking tape are rich and diverse, with widths covering 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, 20mm, 25mm, 28mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 80mm, 100mm, 150mm, 200mm, 250mm, 300mm, 400mm, 500mm and 600mm. In terms of length, standard specifications such as 33m and 66m are provided to meet the needs of different application scenarios.
Masking Tape Colours
Masking tape is colorful, covering classic colors such as blue, green, black, white, red, yellow, orange, etc. There are also purple, brown, and pink to add a warm atmosphere. There are also rainbow colors， tan and gray to show individuality, gold and silver to shine luxuriously, and transparent models are low-key and versatile, with various colors suitable for multiple scenes.
What Is Masking Tape Used For?
Masking tape has a wide range of uses, mainly used to protect areas that do not need to be treated during spraying, painting, and other scenes, ensuring construction efficiency and clear painting edges.
Car spraying: Auxiliary body color separation design to ensure neat color boundaries. Cover non-sprayed parts such as car lights, window frames, wheel hubs, signs, etc., to prevent paint pollution. Cover the surrounding area when partially touching up paint to avoid confusion between old and new paint surfaces.
Wall painting: Cover door and window frames, switches and sockets, baseboards, and other areas to prevent paint pollution. The color separation effect of real stone paint walls (such as two-color walls, gradient colors) helps to divide boundaries. Cover the ceiling or furniture during partial repair to avoid the crossing of old and new colors.
Painting masking: Temporarily mask the edge of paper or a specific area in watercolor and acrylic painting to prevent pigment penetration. And block the non-painted parts of the model (such as eyes and joints of the model).
Circuit board protection: block electronic components and circuits during soldering to prevent short circuits from solder or paint.
FAQ
Is masking tape waterproof?
Masking tape has certain waterproof performance, which needs to be evaluated according to product material, process, usage scenarios, and needs. If you have special waterproof needs, you can choose specially designed waterproof tape.
How thick is masking tape?
The thickness of common masking tape is about 0.05-0.1 mm, and plastic substrate tape is usually about 0.2 mm or thicker.
Masking tape vs painters tape, what’s the difference?
Masking tapes are often called painter tapes, but they are not exactly a product. Painter tapes are special tapes for painting operations, and masking tapes are not only used for painting operations, but can also be used for circuit board insulation, soldering masking, etc.
Is masking tape safe for walls?
When using rough walls, it is recommended to choose low-tack masking tape, which does not easily leave residue and damage the wall after being torn off after painting.
What is masking tape used for in painting?
The main purpose of masking tape in painting is to protect areas that don’t need to be colored. By applying the tape, the boundary of straight lines, curves or geometric shapes can be formed, and a clean edge effect can be obtained after tearing off.
How to remove masking tape without peeling paint?
Within 1-2 hours after painting, the adhesive of the tape has not fully penetrated and cured. At this time, slowly and steadily peeling off the tape at a 45° angle can minimize the risk of lifting the paint film or leaving ragged edges. Low-tack masking tape can usually be removed relatively easily after the paint surface has completely dried. If the paint surface is dry and resistance is encountered during removal, use a hairdryer to heat the tape until it softens, then carefully remove it.
Can you use masking tape for shipping?
Masking tape has low adhesive strength and tends to detach or fail easily under vibration during transportation packaging. Therefore, it is unsuitable as a packaging material for regular shipping scenarios. Masking tape can only serve as a temporary substitute in ultra-short-term, lightweight, and non-commercial transportation. For professional logistics and shipping, it is strongly recommended to use industrial-grade sealing materials (such as OPP strapping tape, cloth-backed tape, or hot melt tape) to ensure cargo safety.
