Adhesive Grade Polyols
Adhesive grade polyols are specially engineered raw materials designed for high-performance bonding systems used in structural and industrial adhesives.
These polyols contribute to strong interfacial adhesion, high cohesive strength, and long-term durability across a wide range of substrates.
They are widely used in construction adhesives, automotive bonding systems, laminations, packaging adhesives, and wood composites.

How Adhesive Grade Polyols Work
Adhesive polyols react with isocyanates or curing agents to form highly crosslinked polymer networks that define bond strength and flexibility.
By tuning molecular weight and functionality, adhesion properties such as peel strength, shear resistance, and elasticity can be precisely controlled.
These systems are optimized for strong bonding on porous and non-porous substrates including metals, plastics, wood, and composites.
