POLIBAND™ - Cold-Applied Tapes for Corrosion and Mechanical Protection
Self-adhesive anticorrosive and mechanical protection mixed tapes PEHM 750
Recommendations:
PEHM tapes are used for coating buried or immersed metal pipes, for on-site coating pipes welding areas or for repairing pipes pre-coated with PE, PP or PUR.
The POLIBAND system made with this type of strip is designed for a maximum continuous operating temperature of 50° C.
Performance:
- very good corrosion and dielectric properties (volume resistance: min 5×1016)
- very good compliance with any unevenness of coating surfaces
- excellent impact resistance
- compatibility with polyethylene, polypropylene, epoxy and polyurethane based insulation systems
- very good resistance to petroleum products
- ensures good maintenance of the integrity of the insulation system in transport, handling and storage of pre-coated pipes.

PRIMER 2002 anti-corrosion primer
PRIMER 2002 is a solution of synthetic elastomers, adhesion and sticky resins, inorganic salts, corrosion inhibitor and hydrocarbon solvents.
PRIMER 2002 is designed for priming metal surfaces in general and specifically for priming metal pipelines for transporting natural gas, oil products and water in new coating systems, when repairing and remediation of degraded insulation systems.
| Characteristic | Value |
| Appearance | Viscous, homogeneous solution |
| Color | Dark yellow - brown |
| Dry matter content | 43 ±3 % |
| Viscosity Ford cup Ø 8 mm | 45±5 % |
| Flash point | Max. 20 o C |
- Surface preparation for PRIMER 2002 application is done by sandblasting, brushing, air blowing or degreasing in order to remove all impurities (rust, metal powders, dust, etc.).
- PRIMER 2002 must be thoroughly mixed before application.
- PRIMER 2002 should only be applied on clean and dry surfaces using a brush or trowel.
- Drying time is approximately 30 minutes, depending on the atmospheric conditions and nature of the substrate.
Packaging
PRIMER 2002 is supplied in sealed metal containers of 20 l capacity.

Heat shrink sleeves
Heat shrink sleeves are a pipe protection system that uses a special material that contracts under the influence of heat, thus creating a protective barrier. This system is useful in situations where pipes are exposed to extreme temperatures, corrosion and other environmental elements, providing an effective and durable solution to protect them from damage and degradation. Heat shrink sleeves are easy to install and provide durable protection, thus ensuring an effective and long-term protection solution for pipes.
We are dedicated to providing our products and services to provide your pipes with the best protection against environmental influences.
