Low price polyfunctional aziridine crosslinker C-100 CAS NO.64265-57-2

Nanjing MSN chemical Co., Ltd was located in Nanjing chemical industrial park, Nanjing city,Jiangsu province, devoted in the research, production and sale of the crosslinkers Trifunctional Aziridine Crosslinker Cas No.:64265-57-2 and BI(Blocked isocyanate) for MDI type blocked isocyanate crosslinker Cas No.: 7417-99-4 . Crosslinkers are widely used in the waterborn acrylic resin and waterborn polyurethane emulsion system, such as leather, printing, dye printing, printing ink, waterborn coating, pressure sensitive rubber.

we are producing Pharmaceutical intermediates:

DHP and ionic liquids and imidazole derivatives

 

Our commitment to our corporate mission lies in our experience in constantly improving chemical synthesis processes. We achieve our aims by providing:

1. An open product list of active substances and fine chemicals that fully comply with current pharmacopoeias and industrial standards.

 

2. Customer manufacturing services for exclusive products with special requirements.

 

2) Application  

In water based parquet lacquers to improve water ,alcohol,detergent Chemical and abrasion resistance
In water based industrial wood-,plastic-and metal coatings to increase water ,alcohol and block resistance

In vinyl coatings to reduce plasticizer migration and improve stain resistance
In water based concrete sealers to improve abrasion
Resistance

Generally,to improve adhesion of water based systems to non-polar substrates
In solvent based polymers to increase resistance properties
In water based printing inks to improve water and detergent resistance 

3) Formulating guidelines   

Crosslinker C-100 is a tri-functional material that crosslinks polymers with reactive carboxyl fun- ctionality

Typical addition levels of it necessary to fully Crosslink acrylic emulsions and urethane dispersions are 2% and 3% respectively 

Polyaziridine should be added to lacquers,paints or inks prior to use and due to its excellent water miscibility it can be stirred in by using a 1:1 premix of polyaziridine and water.

In water borne formulations ,polyaziridine will slowly hydrolyse and blends should therefore be used with- in 3-5 days after preparation.The hydrolised products have no adverse effects on the emulsions nor on the dried films, and additional crosslinker may be added to restore reactivity

Solvent based systems modified by the addition of polyaziridine must be used within 5 days because they tend to thicken and may be gel within 2 weeks
