What Is Airtight Waterproof Tape?
Airtight waterproof tape is a very useful tape because it can be cut by hand and is airtight and waterproof. It is often used at construction sites and in interior decorating because it can be applied to walls, ceilings, and other spaces to maintain waterproofing.
The main colors are white and black, and widths range from 3 to 5 inches. Adhesion can be single-sided or double-sided.
Airtight waterproof tape is also used to repair leaks temporarily and other problems during disasters. It can be used to reinforce window sashes and to join destroyed drywall, making it easy to use and convenient to have one in the home.
Uses of Airtight Waterproof Tape
Airtight waterproof tape is often used to reinforce and protect seams at construction sites. It is also used to seal the joints between layers of insulation sheets, moisture-permeable tarpaulins, and other materials.
In some cases, it is used as an alternative to butyl tape.
Due to its durability and ease of use, it is widely applied in DIY and gardening. Note that the heat resistance temperature varies depending on the product, and the adhesive may deteriorate due to direct sunlight.
Principle of Airtight Waterproof Tape
The airtight waterproof tape consists of a nonwoven fabric on the top surface, with reinforcement, adhesive, and release paper underneath.
Nonwoven fabrics made of polyester, polyethylene, or PET resin are often used as the base material for airtight waterproof tape. In the case of polyester non-woven fabrics, paints can be applied over them so that they can be treated inconspicuously. Products with urethane foam sandwiched between them have high heat insulation properties. In addition, products made of aluminum material have high heat resistance. Aluminum material is also weather-resistant and suitable for repairing exterior walls. However, since it cannot be cut by hand, a cutter or similar tool is required.
Butyl and acrylic adhesives are used. Acrylic-based adhesives are easy to cut by hand, so workers’ hands do not need to get dirty. It also has the characteristic of being difficult to peel off even outdoors. It should not be reapplied, as the adhesive’s adhesive strength will decrease.
The airtight waterproof tape has very high adhesive strength and is durable, and some products can withstand 50 years equivalent of use.
