Typical Properties:



Metal Content


g/cm3 (25℃)


mPa.s (25℃)



yellowish clear liquid




With special odor of chemical compound


Solubility:Soluble in general polyurethane raw materials.


Eco-friendly Characteristic:

It does not contain restricted heavy metals, polycyclic aromatic hydrocarbons, phthalates and other components, and is an environmentally friendly substitute for traditional organotin, mercury, lead and other catalysts.  It can meet the requirements of general environmental protection regulations.



It is widely used in polyurethane industry. It can be widely used in aromatic or aliphatic isocyanate systems such as TDI, MDI, HDI and IPDI, etc. It is recommended for polyurethane CASE (elastomers, two component sealants, adhesives, coatings) products, It is especially recommended for polyurethane soft rubber such as, flexible heel, room temperature curing plastic runway and other elastomer fields.


Features & Advantage:

ZCAT-EZ19 has the typical characteristics of zinc catalyst, the unique characteristics are as following:

  • Post curing catalyst to shorten forming / demoulding / drying time. 

  • The catalytic activity is mild, and it is generally not used alone. It is generally recommended to be used as an auxiliary catalyst in combination with organic bismuth.

  • Good compatibility. It has better solubility than organic zinc catalyst ZCAT-EZ22.

  • Safety and environmental protection; No solvent, the smell is weaker.


User's Guide:

  • It is recommended to be added into polyol components (material P), preferably after vacuum degassing, and stir evenly.

  • It is not recommended to be added into the components of ISO (Material I) due to the risk of gelation. If necessary, be sure to conduct suitability test first.

  • The dosage is related to factors such as formula and process. The general dosage is 0.1 ~ 1% of the weight of polyol components (material P).

  • After use, the tank mouth must be sealed immediately.


Handling & Storage:

Exposure to atmosphere should be avoided. Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain.
