Usage
Dosage is usually 1 to 3% of the solid content of the emulsion. The pH value of the emulsion is preferably 8 to 9.5. It should not be used in an acidic medium. This product mainly reacts with the carboxyl group in the emulsion. It is generally used at room temperature, 60~ The baking effect is better at 80 ° C. The customer should test according to the needs of the process.
This product is a two-component cross-linking agent. Once added to the system, it is recommended to use it within 8 to 12 hours. Use the temperature and compatibility Resin system to test the pot life. At the same time, this product has a slight irritating ammonia smell. Care should be taken to avoid direct contact with skin and eyes. Try to use it in a ventilated environment. Pay special attention to mouth and nose during spraying. Should wear special masks, gloves, protective clothing to operate.
Applications
Widely used in water-based and some solvent-based inks, coatings, pressure-sensitive adhesives, adhesives, etc., it has significant resistance to washing, scrubbing, chemicals, and adhesion to various substrates.
The improvement is the crosslinking agent belongs to an environmentally friendly crosslinking agent, and no harmful substances such as formaldehyde are released after crosslinking, and the finished product is non-toxic and tasteless after crosslinking.
Package and Storage
