PU1200 polyurethane hot melt adhesive
PU1200 is a 100% solids, moisture-reactive polyurethane hot melt adhesive designed for both self-adhesion and mutual bonding of materials such as PC, ABS, PVC, aluminum, stainless steel, and glazed glass. Once applied and cooled, it delivers sufficient initial strength to support subsequent processing steps. After full curing, the adhesive offers outstanding resistance to heat, water, and chemicals, making it particularly well-suited for bonding plastics in electronic applications.

Anticipated matters
Please read the safety manual before use to understand the relevant preventive measures and safety recommendations. For chemicals that do not require labeling, observe in advance and take corresponding preventive measures.
Product Application
It is mainly suitable for bonding various plastics and metals in the electronics industry. The surface properties of each material vary greatly, and it is recommended to conduct pre experiments before use.
Product Operation
The construction site should have a good ventilation system, and the recommended construction temperature is between 100-130 °C.
GBT ViaBON PU1200 belongs to the moisture responsive polyurethane hot melt adhesive category. Please use professional equipment for reactive hot melt adhesives. If ordinary hot melt adhesive equipment is used, it may cause moisture to seep into the product due to poor airtightness, resulting in curing when in contact with the product, which will damage the adhesive machine or affect its use.
Please assemble the parts immediately after gluing, so that the glue can achieve good wetting effect, which will help with the bonding effect.
In order to achieve complete curing, it is best to place the finished product in a suitable working environment with appropriate temperature and humidity (recommended temperature: 23-25 ° C, relative humidity of about 65%).
It is recommended to fully cure the assembled electronic products before conducting subsequent related tests.

Technical Overview & Compliance
Our Polyurethane Hot Melt Adhesive (PUR) combines the processing speed of traditional hot melts with the structural strength of a reactive cross-linking polymer. Once applied, the adhesive reacts with atmospheric moisture to form a permanent, thermoset bond that will not re-melt under high-temperature exposure. This makes it an ideal solution for bonding low-surface-energy plastics, glass, and metals in compact electronic enclosures where thin-line bonding and immediate handling strength are required for automated assembly.
To ensure consistent performance in global manufacturing environments, our PUR formulations are evaluated against the ISO 9142 standard for Adhesives – Guide to the Selection of Standard Laboratory Ageing Conditions. This compliance ensures that the Polyurethane Hot Melt Adhesive maintains its bond integrity against humidity, chemical exposure, and thermal shock. By meeting these international benchmarks, we guarantee a reliable, long-lasting adhesive solution that withstands the rigorous demands of the consumer electronics and automotive industries.
