CX-100交聯(lián)劑Crosslinkingagent

cx-100 crosslinking agent
cx-100 is a trifunctional aziridine crosslinker that does not contain any solvents and has a solid content of more than 99%. it is widely used in the fields of leather, textile, ink, paint, pressure sensitive adhesive, adhesive and curing agent. its cross-linked film products, washing, scrub, chemicals, and adhesion on the substrate have significantly improved;
the cross-linking agent belongs to environment-friendly cross-linking agent and releases no harmful substances such as formaldehyde after the cross-linking, and the finished product is non-toxic and tasteless after the cross-linking;
the amount is usually 1-3% of the emulsion solids content, emulsion ph value is added in the 8-9, should not be used in acidic medium (ph<7);
cx-100 is mainly cross-linked with the carboxyl groups in the emulsion. it can also undergo cross-linking reaction with amine groups and hydroxyl groups under the catalysis of strong acids. therefore, it is necessary to use aprotic organic bases as far as possible when adjusting the ph value of the system.
the aziridine crosslinking agent can occur at room temperature crosslinking reaction, but baking at 60-80 degrees better;
the crosslinking agent is a two-component crosslinking agent, once added to the system should be completed within two days, otherwise it will form a partial gel phenomenon;
the cross-linking agent can be miscible with water and common solvents. therefore, it can be mixed into the system under violent stirring, or it can be dissolved in water and solvent and then added into the system.
the cross-linking agent at room temperature, sealed conditions, storage period of 24 months; non-flammable, explosive products, but a certain corrosive, belong to common commodities.

in water-based fight wood floor paint can improve its water-resistant, alcohol-resistant, detergent resistance, chemical resistance and abrasion resistance;
in water-based industrial paint can improve its water-resistant, alcohol-resistant, anti-sticky;
vinyl coating can reduce the plasticizer migration, improve stain resistance;
in water-based cement sealant to improve its wear resistance;
can generally improve the water-based system in non-porous substrate adhesion.
use and toxicity:
products have a stimulating ammonia taste, long-term inhalation can cause cough, water flow nose, showing a false cold symptoms; contact with the skin will be based on the resistance of different people cause skin irritation, and even goose bumps symptoms, but the general symptoms disappear within 2-6 days, serious cases should follow the doctor&＃39;s advice treatment. so be careful and avoid direct contact with the skin and eyes, as far as possible in a ventilated environment. use spray to pay special attention to the mouth, nose inhalation, should wear a special mask operation.
