Product Description
High heat resistance pressure sensitive adhesive hot melt adhesive.Increasing demand for PUR and POR reactive hot melt glue for automotive adhesives.
The need for reactive hot melt adhesives has never been greater, thanks to their extraordinary strength and versatility. Reactive hot melt glue refer to polyurethane (PUR) hot melts and silane-modified polyolefin (POR) adhesives.
100 % solids content, highest resistance to water and steam after chemical curing.Solvent-freeBoth reactive hot melt adhesive types are used in many industries, including the automotive industry, electronics, and construction.highest heat resistance after chemical curing. In this article, we focus on hot melt glue for automotive industry assembly and repairs.
They can level out of irregularities in the surface.The unique curing process makes PUR and POR hot melt adhesives a desired solution for many automotive adhesive applications. They can be used for example in making seats, gluing carpets, bonding foam-based materials, fixing cables, and attaching door sill protectors, as well as bonding emblems and gear knobs.
Reactive hot melt adhesives are also known as moisture-curing hot melts. This means that the hot melt glue reaches its final cure as it reacts with moisture in the air and substrate. These adhesives have a two-stage curing profile which divides the process into physical and chemical curing.
Shortly after the hot melt glue has been applied, the physical setting takes place. This allows the adhesive to reach a stage of hardness which allows for further processing and transport.
The second stage of curing may take hours or even days, depending on adhesive type and moisture present in the environment. During chemical crosslinking, the hot melt glue loses its thermoplastic properties and becomes thermoset, which means that high heat does not affect it.These are not the only applications for reactive hot melt adhesives: the range of possibilities is nearly limitless. Contact us to discover whether PUR or POR hot melt is the solution for your automotive adhesive application.
