What kind of adhesive is used to bond TPU to acrylic?
14 Nov 2025
KL-363-1 Quick-drying Adhesive: Applications: Suitable for bonding metals, rubber, plastics, wood, foamed substrates, and PP. Colorless and transparent liquid, surface drying time 20-30 seconds, complete drying time 4-8 hours. Features fast drying, strong adhesion, low whitening, and wide applicability.
KL-16UV Adhesive: KL-16UV adhesive features fast drying, ease of use, strong adhesion, and no VOC emissions. Mainly used for bonding PET to PET, PET to ABS, PET to PC, and PET to acrylic.
Two-component structural adhesives: Some two-component structural adhesives can also be used for bonding TPU to acrylic. These adhesives usually require mixing two components before use and feature high strength, impact resistance, and chemical corrosion resistance.
When selecting adhesives, the following factors need to be considered:
Application: Different applications have different performance requirements for adhesives, such as environments requiring high temperature, high pressure, or chemical corrosion.
Operating conditions: Including bonding area, shape, thickness, and whether rapid curing is required. Cost-effectiveness: Choose an adhesive with high cost-effectiveness while ensuring bonding performance.
In addition, the following points should be noted when using adhesive:
Surface Cleaning: Before bonding, ensure that the surfaces of both TPU and acrylic are clean, free of oil and dust to improve bonding results.
Even Application: When applying adhesive, ensure even and appropriate application, avoiding air bubbles or missed areas.
Curing Conditions: Select suitable curing conditions, such as temperature, time, and UV intensity, based on the type and requirements of the adhesive.
In summary, choosing a suitable adhesive and following the correct application methods can achieve a strong bond between TPU and acrylic.
