| High Light | Fast-Curing Epoxy Primer ，Solvent-Free Heat Shrink Sleeve Primer ，Excellent Cathodic Disbondment Resistance Pipeline Joint Primer | ||
Fast-Curing, Solvent-Free Epoxy Primer for Heat Shrink Sleeve Installation
Product Introduction
Our two-component epoxy primer is engineered specifically as the critical bonding layer in heat shrink sleeve systems for pipeline field joint corrosion protection. Formulated with a 100% volume solids, solvent-free epoxy resin system, it delivers exceptional adhesion to blast-cleaned steel and compatible factory coatings while providing outstanding cathodic disbondment resistance—the key performance indicator for long-term pipeline integrity.
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.
Heat-Assisted Force Cure: Available for accelerated curing when required, further shortening installation cycles.

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
