PUR (Polyurethane Reactive), full name is moisture curing reactive polyurethane hot melt
Adhesive. The main component is isocyanate-terminated polyurethane prepolymer. The adhesion and toughness of PUR (elasticity can be adjusted, and it has excellent adhesion strength, temperature resistance, chemical resistance and aging resistance.

Reactive hot melt adhesives are heated before processing and applied in molten state. When the adhesive cools down, it builds up its green strength through a physical hardening process. Water molecules (from the substrate or the air) then trigger a chemical reaction which transforms the adhesive into an elastomer. After complete crosslinking, reactive hot melt adhesives provide a stronger bond with a superior resistance against moisture, heat and chemicals.

PUR hot melt adhesive has become one of the important varieties in the adhesive industry in recent years. Now it is widely used in Edgebanding,Profile Wrapping,Flat Lamination,Foam Lamination,ect

Due to its extremely high reactivity, it exhibits excellent adhesion to a variety of materials.
It is also widely used in the Foam Lamination, Paper packaging, book binding, Manufacture of Laminate-, Vinyl-, Design Flooring, Composite Elements, etc.

PRODUCT FEATURES

It is adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product.

Winlong pur hot melt adhesive products have the following advantages:

• It is solid, and when heated to a certain extent, it melts into a liquid and is applied to the substrate, and it will not be melted twice after curing.
• moisture curing, no drying process, fast energy saving; the adhesive layer has certain flexibility, hardness and certain toughness.
• excellent initial strength, and cross-linking curing function, the final bonding strength is higher;
• Because the product itself is solid, it is convenient for packaging, transportation and storage.
• It does not contain any organic solvent, the solid content is 100%, non-polluting, non-toxic, green and environmentally friendly.
• excellent heat resistance, water resistance, chemical resistance, durability, etc.
