Born2Bond PUR high-performance hot melt adhesives from Bostik are designed for industrial applications requiring precision, mechanical strength, and long-term reliability.
The range Born2Bond The HMPUR HHD Series comprises reactive polyurethane-based hot melt adhesives, also known as PUR hot melt or HMPUR adhesives. These one-component solutions are applied hot and then react with ambient moisture or the moisture present in substrates to form a durable cross-linked bond.
This technology is particularly suited for industrial environments where manufacturers are looking for fast, precise bonding compatible with high production rates. It specifically meets the needs of the electronics, portable devices, industrial equipment, automotive, display, and small technical assembly sectors.
Born2Bond PUR hot melt adhesives combine the speed of a hot melt adhesive with the ultimate performance of a reactive adhesive. They are used when bonding requirements demand good adhesion to various materials, controlled application, and resistance suitable for end-use conditions.
The exact features vary depending on the references within the HHD Series range. The principal technical elements to consider are:
Features | Description |
Type of adhesive | Polyurethane reactive hot melt adhesive, or PUR. |
Technology | Moisture-curing one-component adhesive. |
Method of application | Hot application, with progressive hardening after removal. |
Formulation | Solvent-free solutions by grade. |
Properties after hardening | Formation of a thermosetting cross-linked joint. |
Viscosity | Several levels available to adapt to dispensing, deposition, and assembly processes. |
Open hours | Variable depending on the references, in order to adapt to positioning and assembly constraints. |
Substrate Compatibility | Adhesion possible on various materials, including certain plastics, metals, glass, and technical components, subject to validation by testing. |
Thermal resistance | Good thermal stability according to references and usage conditions. |
Born2Bond PUR hot melt adhesives are designed to integrate into manufacturing processes where assembly speed, dispensing accuracy, and repeatability are essential. Their hot application allows for a fast initial grab, while benefiting from reactive curing after application.
This combination is interesting for manufacturers who wish to optimise their cycle times without compromising the final bonding performance.
Once applied, the adhesive reacts with moisture to form a cross-linked seal. This mechanism helps to improve the final strength of the assembly, particularly in applications where the bond needs to withstand mechanical, thermal, or environmental stresses.
Depending on the selected grade, the range can offer a balance of strength, flexibility and stability over time.
The products from the Born2Bond HMPUR HHD Series can be used on different types of industrial substrates. This versatility is useful in sectors where the same part combines multiple materials: engineering plastics, metal inserts, glass, electronic components, or decorative elements.
Preliminary tests remain recommended to validate adhesion, surface preparation, open time, and joint behaviour after ageing.
The miniaturisation of industrial components requires adhesive solutions that can be precisely dispensed onto small and sometimes complex-to-access areas. Born2Bond PUR hot melt adhesives meet these constraints thanks to their compatibility with controlled dispensing processes.
They are particularly relevant in applications where mechanical fastenings are difficult to integrate or generate too much bulk.
In portable electronic devices, components must be assembled with precision while maintaining good long-term durability. Constraints can include miniaturisation, vibrations, repeated contact, exposure to heat, or aesthetic requirements.
Born2Bond PUR hot melt adhesives enable localised and precise bonding on small components. They can be used for the assembly of housings, internal modules, protective elements or structural parts in wearable devices.
Screens, touch panels, and display modules require bonding solutions that can ensure precise positioning and a secure hold of components. Industrial needs often focus on joint stability, cleanliness of application, and compatibility with sensitive substrates.
The Born2Bond HMPUR HHD Series range can meet these needs through controlled application, good adhesion to various materials, and open times suited to assembly operations.
In certain industrial equipment, bonding can be used to replace or supplement traditional mechanical fasteners. It can help to reduce the number of components, limit drilling points, and improve the distribution of stress across the assembled area.
High-performance PUR hot melt adhesives are suitable for lightweight structural assemblies where the specification demands reliable mechanical strength, rapid application, and compatibility with a variety of materials.
In the automotive sector and for on-board equipment, adhesive solutions must meet constraints related to durability, temperature, vibrations, and compatibility with various materials.
Born2Bond PUR hot melt adhesives can be used for interior assembly applications, component fixing, electronic modules, display elements or technical parts. They allow for clean and repeatable bonding, suitable for the demands of industrial production lines.
The choice of an industrial adhesive is not solely based on product performance. It also depends on its compatibility with materials, its behaviour during production, the application method, and the end-use constraints.
When working with a partner capable of combining product expertise Bostik This provides an understanding of industrial processes, manufacturers benefit from more comprehensive support. The objective is to propose an adhesive solution that is consistent with the technical requirement, but also realistic to integrate into a production environment.
A PUR hot melt adhesive is a reactive polyurethane-based adhesive applied hot. After application, it reacts with ambient humidity or the humidity of the substrates to form a cross-linked bond. This technology combines the speed of implementation of a hot melt with enhanced final performance after curing.
A classic hot melt hardens primarily through cooling. A PUR hot melt, on the other hand, first hardens by cooling and then continues its chemical reaction with moisture. This reaction results in a more durable and resistant bond than a standard hot melt in many industrial applications.
The range can be used in electronics, portable devices, display modules, automotive, industrial equipment, and miniaturised technical assemblies. It is ideally suited for applications where dispensing precision, durability, and multi-material compatibility are important.
Yes, certain grades can be compatible with different engineering plastics. However, adhesion is highly dependent on the nature of the plastic, its surface energy, surface preparation, and application conditions. Validation tests are recommended before any series use.
The choice of grade depends on several criteria: materials to be assembled, mechanical constraints, operating temperature, expected flexibility, available open time, application method, and final environment. A preliminary technical analysis allows the most suitable reference to be selected and the solution to be validated through testing.
