Bio-based Polyol Adhesive

【Product Description】

Bio-based polyol adhesive is a new functional and environmentally friendly product launched by our company to address climate change. Its main resin is a high-hydroxyl polyol made from natural renewable materials, and the curing agent is a low-viscosity, highly reactive polyisocyanate. This product contains no solvents, offers high strength, and combines low-carbon environmental protection with excellent practical performance, making it a new type of multi-functional adhesive.

【Product Category】Two-component polyurethane adhesive.

【Product Advantages】Performance comparison for construction pavement applications

【Application Scope】Permeable pavements, courtyard decoration, road paving, repair, sand consolidation, other structural adhesives, etc.
