PUR Adhesives
Three features to love: one-part application, rapid handling strength and high final strength.
The strength of a structural adhesive with the speed of a hot melt
-
Polyurethane reactive adhesives (PUR adhesives) are one-part formulations that combine the initial speed of a hot melt adhesive with the strength of a structural adhesive. The bond forms in two stages: when the adhesive cools back down and solidifies like a hot melt it reaches holding strength, then the moisture-curing reaction proceeds over the next 24-48 hours to reach final structural strength. These adhesives are resistant to temperature extremes and flexible to provide vibration and impact resistance.
3M™ Scotch-Weld™ PUR Adhesives have a range of open times that can be adjusted to suit your process, and they have low to no VOCs. These adhesives bond well to metals, glass, ceramics, wood and some plastics such as polystyrene and polyacrylic. The combination of no-mix one-part application, rapid handling strength and high final strength makes PUR adhesives excellent candidates to help improve throughput and reduce processing time.
After cooling, PUR adhesives use ambient moisture to continue curing for hours to days while increasing in strength
