CUCAT-HC is suitable for micro foaming playground materials. When used in combination with organic bismuth / zinc, it can adjust the foaming ratio, provide fine and uniform micro foaming effect, have good surface flatness after curing,and avoid large bulges.
Product Model: CUCAT-HC
Typical Properties:
Appearance: Clear, light yellow transparent liquid
Chroma (APHA): ≤200
Density (g/cm3, 25℃): 1.032
Viscosity (mPa.s, 25℃): 75
Solubility: Soluble in normal polyurethane raw materials (polyether polyol, plasticizer)
Applications:
CUCAT-HC is a wide applicable catalyst to be used in 2K PU systems in CASE applications, specially recommended for the MDI+polyester+BOD systems.
Features & Advantages:
High catalytic selection. Effectively catalyze the reaction between isocynates and hydroxyl, balance the reaction activity.
Long pot life to provide favorable flowing property. Slow catalytic rate at early reaction stage can keep low viscosity and improve flowing ability, which is important for reducing mechanical bubbles and filling moulding chamber rapidly.
Catalytic rate accelerate very quickly at post curing reaction stage. CUCAT-HC can catalyze isocyanates-polyols mixture to attain required curing strength quickly during the post curing stage, specially in MDI+polyester+BOD systems showing excellent performance.
User's Guide:
♢ Suggest adding in polyol component after vacuum degassing.
♢ Levels of 0.1-0.5% as supplied by weight on total polyol volume.
Handling & Storage:
CUCAT-HS is sensitive to moisture. There, exposure to atmosphere should be avoided. 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
