Introduce:
- Ingredients: derived from modified polycarbamin acid, a 1-component glue, no solvents;
- Use in temperature range : -40 0 C ~ 130 0 C, depending on the application;
- Compliant RoHS standard 2015/863/EU;
- Does not contain halogen elements according to IEC 61249-2-21;
- Compliant with the VOC content limit according to GB33372-2020 regulations;
- The glue can be quickly fixed by light, then cured at low temperature (+80 oC), heat curing is required for the glue to fully cure.
Application:
- Specialized glue in gluing electronic components, smartphone camera modules, automotive cameras, ...
- Adhesive to a variety of materials such as glass, aluminum, PC plastic, FR4, GF30, ...
- To use the adhesive effectively, it is recommended to place the glue in the DELO's specialized dispersion, the surface to be bonded should be clean, dry, free of dust or grease;
- For a clean and well-activated surface, use DELOTHEN facial cleansing spray.
