Description

Product Model: CUCAT-SW02D


Typical Properties:

Appearance: Light yellow to red transparent liquid

Density (g/cm3, 25℃): 1.060

Viscosity (mPa.s, 25℃): 5 ~ 40

Smell: With special compound smell


Applications:     

It is suitable for polyurethane synthesized from polyester polyols, especially adipic acid polyester polyols, such as “MDI + polyester polyol” and other material of two or three components using small molecular alcohols such as butanediol or ethylene glycol as curing agent, polyester polyol combination such as “TDI + MOCA or other small molecular alcohol as chain extender and curing agent”. It is suitable for normal temperature and medium temperature curing process, typical applications such as transparent outsole shoe glue, KPU vamp glue, mine screen, caster, etc.

 

Features & Advantages:

CUCAT-SW02D is specially developed for polyester polyol polyurethane system. Different from common amine / tin catalysts, CUCAT-SW02D has the following characteristics:

● Tin free: meet the environmental protection requirements of shoe materials, clothing and other export products.

● No bulging and reduce bubbles: the unique targeted catalytic characteristics can effectively reduce CO2 bubbles generated by the reaction of trace water with isocyanate and avoid quality problems such as bulging, bubbles and cracking.

● Low viscosity and long flow period, no fracture of fine glue filament: the initial viscosity of material mixing rises slowly and has good fluidity. It can quickly fill the complex mold cavity to ensure the continuous gluing of fine patterns of complex molds.

● Fast post curing speed: the strength of the gel rises quickly after gelation, and improves the production efficiency.

 

User’s Guide:

◢ It is recommended to be added into polyol (material P) on site during production and stir evenly. If there is a vacuum process, it is recommended to add it after dehydration / degassing; It is not recommended to be added into ISO (I) components, for the long-term storage may have a risk of gelation. If added, risk assessment is needed. 

◢ The dosage is related to the formula and process. The general dosage is 0.05 ~ 0.5% of the weight of P material. 

◢ During normal use, ensure that the cup or other container containing the product is clean and dry, and ensure that the tank mouth is closed immediately

◢ It is normal that the color of the product may gradually darken during storage, which generally will not affect the color of the product.

 

Handling & Storage:

Product should be stored in a cool, dry environment away from sunlight and excessive heat.

 

Package: 25kg / 200kg in HDPE drum

 

Shelf Life: The unopened shelf life is 12 months from the date of manufacture. After shelf life, please do test to make sure the catalytic properties before use.
