Introduce:
- A glue that is compatible with both heat and UV curing methods;
- Ingredients: double curing modified polycarbamine acid derivative, 1-component glue, solvent-free;
- Especially for quick fixation of components that need to be cured at low temperature;
- Cured products are generally used in the temperature range of -40°C to +130°C; depending on the application, other limits may be more reasonable;
- Complies with RoHS directive 2015/863/EU;
- Halogen-free according to the criteria of IEC 61249-2-21;
- Compliant VOC content limit according to GB33372-202 criteria.

Application:
- Applied in many fields, especially the production of electronic components, microchips, electrical engineering, telephones... used for quick fixation of components after irradiation, bringing high durability.
- Glue is manufactured to be ready to use, if stored in cold storage, the glue needs to wait to room temperature before use. For 10 ml glue vial is 0.5h, 160ml is 2h and 600ml is 5h, no heating is allowed;
- The adhesive surface needs to be dry, clean of grease, durt, acetone, and butyl diglycol acetate can be used to clean the surface. Do not use ethanol or water to clean the surface.
- The glue should be placed in the specialized adhesive dispensing system DELOMAT 100.

Curing:
- Pre-fixation to UVA light in the wavelength range 320 - 400 nm from 1 - 5 seconds; time to fix the joint does not exceed 1h, it is required to cure by heat at a temperature from +80 ° C to + 130 ° C.
