Improved load-bearing capacity and seismic resistance |
DX3211 is mainly used for polycarbonate bonding, without causing stress cracking on the usual substrate, and its toughness improves load-bearing and seismic resistance. Has excellent bonding ability for glass, various plastics, and most metals. The thixotropic properties reduce the flow of liquid 3103 after glue application and before solidification.

Typical curing characteristics:
DX3211 will cure under sufficiently strong ultraviolet and/or visible light. The use of 220 to 260 nm ultraviolet light is beneficial for surface curing. The curing speed and final depth are affected by light intensity, pop distribution, irradiation time, and substrate transmittance. Note: The ultraviolet intensity mentioned here was measured at 365nm.
Stress cracking
Apply the adhesive onto the polycarbonate bent strip, measuring 6.4cm x 13mm x 3mm, and bend it to a certain stress level.

User Guide:
1、 This product has photosensitivity. When storing, it should be kept away from sunlight, ultraviolet light, and artificial light sources.
2、 This product should be coated with black rubber hose.
3、 To achieve the best bonding performance, the surface of the material being bonded should be clean and free of grease.
4、 The curing depth depends on the intensity of the light source, distance from the light source, curing depth, bonding gap, and material transmittance.
5、 The recommended minimum light intensity for the bonding area is 5 mW/cm2, and the required time is 4-5 times the initial curing time under the same light intensity.
6、 To achieve surface dryness, higher intensity ultraviolet radiation (100 mW/cm2) is required.
7、 For temperature sensitive substrates, such as thermoplastic, cooling is required.
8、 Crystalline and semi crystalline thermoplastic materials need to be checked for stress cracking caused by contact adhesive.
9、 Excessive uncured adhesive can be wiped away by organic solvents (such as acetone).
10、 Adhesive components should be cooled before bearing any load.
