What is "polyurethane-type reactive hot melts (PUR-HM)" that cures with moisture?
This product is a general hot melts with reactivity, and is solvent-free, highly heat resistant, and highly durable.
It hardens in response to moisture (moisture).
*Polyurethane Reactive hot melts pressure sensitive adhesives (PUR-adhesives)
Characteristics
- Solvent-free and moisture-curing, so CO2 emissions and energy consumption are lower than solvent-based systems (SDGs compliant)
- Heat resistance and adhesive properties are equivalent to solvent-based acrylic adhesives
- High-speed coating possible

Heat-resistant PUR-HM pressure sensitive adhesives
Using our unique monomer design technology, we have succeeded in creating a tackiness even though it is PUR-HM, making it possible to make PUR-HM into a sheet, which was previously difficult.
A patent is currently pending.
Characteristics
- Since it does not use organic solvents, it can be used in applications that require environmental consideration.
- It has higher heat and cold resistance than conventional products, making it suitable for automotive and building materials applications.
- Since it has a solid content of 100%, there is no need for a drying process when creating sheets.
Assumed use for automobiles
- Assembling the seat
- Fixing the interior (doors, ceiling surface materials)
- Decorative film for interior protection

PUR-HM adhesives for textiles
A PUR-HM adhesives with flexibility and durability that meets the demands of textile applications.
Because it has a low melt viscosity and can be applied at low temperatures, it can be applied to and adhered to olefin fabrics.
Application
- Fabric lamination for outdoor use (waterproof/windproof)
- Seamless for underwear (improved feel)
