KOWRAP
HEAT SHRINKAGE TAPE
Kowrap consists of a cross-linked polymer backing and heat-sensitive sealant adhesive, and it is predesigned to be easily installed without a separate priming (liquid adhesive) process. Power Tool Cleaning SSPC.SP3/St.3 or Hand Tool Cleaning (SSPC.SP2/St.2) surface treatment is required depending on the job conditions, and after heat is applied to the sleeve, it shrinks in size and conforms to the pipe surface.
During the recovery stage, softened mastic adhesive flows to form a perfect bond with the pipe surface providing absolute protection against corrosion. Kowrap is highly versatile and compatible with common coating materials such as PE, PP, FBE, PU, Coal Tar, Tape, Asphalt, etc.
Kowrap offers a 2-layer high tack mastic sleeve and a 3-layer sleeve with epoxy primer for various operating temperatures. The differences are determined by designed pipe operating temperatures, coating specifications, and the usage of the pipe.
Kowrap 2-layer heat shrinkable sleeve system complies with most of the required coating specifications such as DIN EN 12068, ISO 21809-3, etc. and it can be used at a maximum operating temperature of 100ºC depending on environmental and mechanical conditions. It is produced with various widths, thicknesses, and designed operating temperatures depending on the client’s requests or coating specifications.
KOWRAP 3-layer heat shrinkable sleeve is designed for operating temperature up to 85ºC. It is compatible with a broad range of pipe coatings (PE, PP, FBE and etc.) that allow application versatility. Innochem’s top-notch adhesive technology allows superior bonding performance and cross-linked backing offers the optimum solid wall against environmental attack and moisture intrusion complying with DIN EN 12068 and ISO 21809-3 International Standards. It is produced with various widths, thicknesses, and designed operating temperatures depending on the client’s requests or coating specifications.
