In the world of oil, gas, and water transmission, the longevity and integrity of steel pipelines are paramount. Major infrastructure projects, rely on advanced anti-corrosion systems to guarantee decades of uninterrupted service.
Our focus is on the critical adhesive layer within the Three-Layer Polyethylene (3LPE) coating system, a globally recognized standard for pipeline protection. This sophisticated system comprises three components: a Fusion Bonded Epoxy (FBE) primer, which offers an initial barrier and strong adhesion to the steel; a robust Polyethylene (PE) topcoat for mechanical strength; and, most critically, the Tie-layer Adhesive to ensure these two chemically distinct layers form a single, inseparable shield.
Our Grafted Polyethylene Adhesive Resins are specifically engineered to optimize this bond. By introducing maleic anhydride functional groups to the polyethylene backbone, our adhesives achieve a high degree of chemical affinity with the epoxy layer, dramatically enhancing the overall adhesion and resistance of the coating system.
This superior tie-layer performance is essential for:

The Aria Adhesive 4107T305 is a premium, maleic anhydride grafted polyethylene adhesive resin, meticulously engineered as the high-integrity tie layer in PE 3-layer coated steel pipes. Supplied in its easy-to-handle pellet form, this grade is the trusted solution for coaters demanding uncompromising performance.
Its primary function is to forge a crucial and robust chemical bond. It significantly improves the adhesion between the corrosion-inhibiting Fusion Bonded Epoxy (FBE) primer and the mechanically tough polyethylene topcoat, effectively locking the three-layer system into a cohesive, protective shield.
The robust structure of this polymer ensures exceptional durability, providing a reliable shield for coated steel pipes operating across demanding temperature profiles, from high-heat service to sub-freezing environments. Its advanced formulation delivers high tensile strength and impressive resistance to strain, directly contributing to the overall mechanical resilience of the pipe coating. Utilizing Aria Adhesive 4107T305 provides project developers and coaters with the assurance of superior peeling strength, a vital indicator of long-term coating stability and enduring performance in critical infrastructure.
Aria Adhesive 4107T267 is an advanced, maleic anhydride grafted polyethylene resin supplied in pellet form. It is specifically engineered as the essential tie-layer adhesive in the industry-standard 3-layer polyethylene (3LPE) coating system for steel pipes, setting a new benchmark for pipeline corrosion protection.
This adhesive creates a strong chemical bond between the inner Fusion Bonded Epoxy (FBE) primer and the outer polyethylene top coat. This function provides superior adhesion to prevent coating failure, offering a balanced polymer profile with excellent flexural properties and robust tensile strength to withstand pipeline stresses. The resulting 3-layer system delivers high peeling strength to prevent cathodic disbondment and corrosion. It maintains structural integrity and adhesive performance across a wide range of operating temperatures, ensuring long-term reliability and cost-effectiveness for energy and water infrastructure projects globally.
