CUCAT-E02 is developed according to the bubble free requirements of products in the CASE field of polyurethane (especially polyurethane elastomer). Different from common amine and tin catalysts, its unique targeted catalytic characteristics (water suppression function) of not catalyzing the reaction between trace water and isocyanate can effectively reduce the reaction between trace water contained in raw materials / substrates / air and isocyanate, and avoid the resulting CO2 bubbles (It can be used for polyether polyols without high-temperature vacuum dehydration). Even in wet and rainy weather, it can effectively prevent the product from foaming, cracking, bulging, peeling and other phenomena. This characteristic is very similar to organic mercury, and it is an ideal substitute for highly toxic organic mercury catalysts.
Typical Properties：

Solubility：Easily soluble in general polyurethane raw materials, such as polyether, polyester polyol, etc
Eco-friendly Characteristic:
The polyurethane material synthesized with this product meets the latest limit requirements of the 17 heavy metals, azo, phthalates and other restricted components, and can pass the latest version of toy environmental protection regulations EN71-3:2019. It is an ideal substitute for eliminating organic mercury, lead and other catalysts.
Applications：
l CUCAT-E02 used in aromatic amine curing system can effectively reduce the discoloration of amine, which is very important for the production of transparent products. It is very suitable for DETDA (E-100) as curing agent to produce the combination material of colorless and transparent skate roller.
l E02 is an upgraded version of E01. Without shortening the flow time, it improves the catalytic efficiency after gel and further shortens the demoulding time.
l It can be widely used in the CASE field of polyurethane to produce skating wheels, two-component sealant, coating, adhesive, etc.

User's Guide:
It is recommended to be added into polyol (material P), add it after vacuum degassing and stir evenly. If it must be added into the isocyanate (ISO, I) component, the applicability test must be carried out first to avoid the risk of gelling in the tank.
The dosage is related to the formula. The general dosage is 0.1 ~ 0.3% of the weight of P material.
Handling & Storage:
Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain. After normal use, the tank mouth must be closed immediately to avoid open placement;It is normal that the product color may gradually become darker during storage, which will not affect the catalytic efficiency.
Package: 25kg/200kg in HDPE drum
Shelf Life: The unopened shelf life is 18 months from the date of manufacture. After expiration, it can still be used if the catalytic activity does not change.
