PUR Adhesive Lamination Specialists
PUR adhesive, also called Polyurethane Reactive (PUR) Hot Melt Glues, is 100% solid content, isocyanate (NCO) capped adhesive.
PUR will contact with the moisture in the air, and allow it to form stronger bonds after the curing process is completed. PUR has the highly flexible and strong adhesion, and suitable for wide range of climates.
Got two materials that just won’t bond? Try Polyurethane Reactive (PUR) – an adhesive that is probably in the shoes you’re wearing and the chair you’re sitting on. It forms strong bonds with different materials with superior resistance against moisture, heat, and chemical. Perfect for bonding difficult materials.
How does PUR work?
You heat the PUR to a molten state and upon application, an instant bond is created between the materials until it cools. A chemical reaction builds up the strength of this bond over the next 72 hours as water molecules in the atmosphere transform the adhesives into a thermosetting polymer.
It's like setting concrete. When you first use it, it is soft and weak, but over a few days, it sets harder and harder until it's like rock. The PUR starts off weak, but as it cures over a few days, it becomes one of the strongest bonds available.
What can PUR be used for?
Due to its ability to bond different materials, PUR is used to bond almost everything. When you get in the car, PUR adhesives have been used to make the seats, glue the carpet, and even fix cables. Your home furniture may have been used to assemble your wooden cabinets or drawers. Even the shoes you’re wearing have been bonded together using PUR adhesive.
Why should you use PUR hot melt?
Bonds an impressive range of materials – including metal, Styrofoam and even stone!
Chemical change, not just a thermal bond
Waterproof (perfect for swimming pool covers)
Bond remains strong at higher temperatures (super effective indoors and outdoors)
Quicker cure time than other traditional hot melts
Won’t shrink or curl when set
Can be sanded and painted
