Solvent-Free Epoxy Primer for PE, PP & FBE Coated Pipeline Heat Shrink Sleeves
Product Introduction
Solvent-free epoxy system specifically engineered for pipeline field joint corrosion protection. Fully compliant with ISO 21809-3 requirements, it serves as the critical bonding layer in heat shrink sleeve systems, ensuring field joints achieve the same level of protection as the mainline coating.
Key Features & Benefits
Superior Adhesion: Bonds firmly to steel substrates and compatible mainline coatings (PE, PP, FBE), creating a durable foundation for the shrink sleeve adhesive layer.
Excellent Cathodic Disbondment Resistance: Effectively resists coating disbondment under cathodic protection conditions, ensuring long-term corrosion protection in buried and immersed pipeline environments.
Fast Curing: Rapid cure allows quick overcoating with heat shrink sleeves, reducing field application time and improving project efficiency.
High-Build Application: Can be applied at recommended thicknesses of 100–200 μm in a single pass, ensuring complete surface coverage.
Solvent-Free & Environmentally Friendly: 100% volume solids formulation minimizes VOC emissions and eliminates solvent entrapment risks.
Key Characteristics
| Aspect | Details |
|---|---|
| Composition | Two-component, 100% volume solids (solvent-free) epoxy resin system |
| Function | First layer of three-layer shrink sleeve system; prepares steel surface for adhesive bonding |
| Key Performance | Excellent cathodic disbondment resistance, fast curing, high-build application, strong adhesion to steel and factory coatings |

System Integration
This primer is designed to work as an integrated component of heat shrink sleeve systems, compatible with common field joint coating configurations including three-layer PE and PP systems. When used with compatible shrink sleeves, the complete system meets the requirements for operating temperatures up to 100°C or higher depending on grade. The epoxy layer provides the critical bond between the steel substrate and the shrink sleeve adhesive, forming a durable, watertight corrosion protection structure for pipeline field joints
