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.

Important Information
Safety Precautions
Before using this product, please read the safety manual carefully to understand the necessary precautions and safety guidelines. Even for chemicals not requiring hazard labeling, it is essential to assess risks beforehand and implement appropriate safety measures.
Product Application
This adhesive is primarily designed for bonding various plastics and metals in the electronics industry. Since material surface properties can vary significantly, it is strongly recommended to conduct preliminary tests before actual use.
Product Usage Instructions
- Ensure the workspace is well-ventilated. The recommended application temperature ranges between 100–130°C.
- PU1200 is a moisture-curing polyurethane hot melt adhesive. It must be applied using equipment specifically designed for reactive hot melt adhesives.
Using standard hot melt machines may result in moisture ingress due to inadequate sealing, leading to premature curing, equipment damage, or poor performance. - Assemble components immediately after glue application to ensure effective wetting and optimal bonding performance.
- For complete curing, allow the bonded product to rest in a controlled environment with a recommended temperature of 23–25°C and approximately 65% relative humidity.
- Ensure the adhesive has fully cured before conducting any follow-up testing on the assembled electronic components.
Cleaning Instructions
- For uncured adhesive, clean the application equipment with a specialized cleaning agent and rinse thoroughly.
- Cured adhesive is difficult to remove and may require prolonged soaking in NMP (N-Methyl-2-pyrrolidone) solvent for effective removal.
Packaging Options

Safety Notes & Handling Precautions
- This product is a reactive polyurethane adhesive. It is not recommended for personnel with known sensitivities or allergies to polyurethane compounds.
- Due to high-temperature application, always wear suitable protective clothing, including gloves, safety goggles, and other personal protective equipment (PPE).
- The product is ready-to-use; avoid prolonged exposure to air to prevent premature curing.
- Follow first-in, first-out (FIFO) practices for inventory usage.
- Cleaning agents are single-use only and must not be mixed back into the adhesive.
- No eating, drinking, or smoking is permitted in the work area.
