Waterproof Self-Adhesive Sealing Strip is a pressure-sensitive sealing material for joints, overlaps, edges and interface areas requiring moisture protection. It consists of a flexible backing, pressure-sensitive adhesive layer and optional release liner.
The construction can be specified by backing material, adhesive type, total thickness, width, roll length and core size. The selected combination can be matched to the substrate, joint dimensions and application process.

Product Construction
Flexible Backing
PE film and other compatible flexible backings provide the base structure of the strip. Backing selection is related to flexibility, thickness, surface compatibility and the geometry of the sealing area.
Pressure-Sensitive Adhesive
Acrylic or rubber-based pressure-sensitive adhesive can be selected according to the substrate and required bonding characteristics. Adhesive coverage and coat weight are controlled during production.
Release Liner
Paper or film release liners protect the adhesive before application. Liner width and extension can be specified according to handling and installation requirements.

Key Product Advantages
Controlled Sealing Area
Specified tape width and adhesive coverage provide a defined bonding area across joints and overlaps. This supports consistent placement when the sealing width is part of the assembly specification.
Flexible Joint Coverage
The flexible backing can follow flat surfaces and moderate changes in surface direction. This allows continuous coverage across joint lines, edges and interface areas.
Process-Compatible Rolls
Roll length and core size can be matched to converting, dispensing and installation requirements. Slit widths can also be specified for different joint dimensions.

Typical Applications
Waterproofing Membrane Joints
Applied across compatible membrane overlaps and joint lines where a pressure-sensitive sealing layer is required.
Panel and Sheet Interfaces
Used on selected panels, sheets and flexible materials to cover connected surface areas and interface lines.
Edge and Perimeter Sealing
Applied along material edges, transitions and perimeter sections where a defined adhesive sealing zone is required.
Industrial Flexible Materials
Suitable for compatible films, sheets and other flexible materials when the backing and adhesive construction match the substrate.

Selection Criteria
Substrate
Confirm substrate material, surface condition and adhesive compatibility before specification. PE films and other low-surface-energy materials require an adhesive system selected for the actual surface.
Joint Width
Select tape width according to joint dimensions and required overlap. The adhesive area should provide sufficient contact across the intended sealing interface.
Application Conditions
Application temperature, surface cleanliness and applied pressure affect adhesive contact. These conditions should be included when selecting the adhesive construction.

Reference Specifications

Converting and Supply Options
Slitting
Master rolls can be slit into specified widths for different joint dimensions and installation requirements.
Roll Configuration
Roll length, core size and winding configuration can be specified according to the dispensing and installation process.
Dimensional Control
Tape width, total thickness, adhesive coverage and liner alignment are checked during coating, laminating and slitting operations.

Quality Control Points
Adhesive Coating
Adhesive coverage and coating consistency are checked across the specified bonding area to maintain uniform contact.
Dimensional Inspection
Width, thickness, roll length and core dimensions are measured against the agreed specification.
Visual Inspection
Backing condition, adhesive coverage, liner position, edge quality and roll winding are inspected before packing.

Packaging and Storage
The sealing strips should remain in their original packaging and be protected from heat, moisture, dust and direct sunlight. Rolls should be stored under stable conditions and protected from deformation.
Storage temperature, humidity and shelf-life requirements should follow the selected backing and adhesive construction.

Application Check
Surface Preparation
The substrate should be clean, dry and free from dust, oil and loose particles before application.
Trial Application
A representative trial should be completed when the strip is applied to a new substrate, coating or surface treatment.
Application Pressure
Firm, even pressure should be applied across the sealing area to establish contact between the adhesive and substrate.
