Product Description

Epoxy Primer A &B for Heat Shrink Sleeve Systems

Product Introduction

Our two-component epoxy primer is specifically formulated as the first layer of a three-layer heat shrink sleeve system for pipeline field joint corrosion protection. The solvent-free epoxy composition provides a high-build, fast-curing base that bonds firmly to blast-cleaned steel and compatible factory coatings, ensuring the shrink sleeve adhesive achieves durable peel strength and superior cathodic disbondment resistance.

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
Compatibility	PE, PP, FBE, PU, CTE, and bitumen mainline coatings
Application	Manual or machine application by hand, roller, or spray; applied to prepared steel surface before sleeve installation
Technical Standards	Compliant with ISO 21809-3, EN 12068, DIN 30672, and applicable GB/T standards

Typical Properties

Property	Typical Value
Type	Two-component, solvent-free
Color	Black
Recommended Thickness	150–500 μm
Pot Life (23°C)	Approximately 20 minutes
Mixing Ratio	Varies by product (e.g., 100:28 or 4:1 by weight/volume)
Curing	Heat-assisted curing available for force-cure systems

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
