Key Performance Benefits
-
Exceptional Shelf Life: Formulated with low selectivity towards isocyanurate, allophanate, and biuret reactions, making it highly stable for One-Component Foam (OCF) and sealant storage.
-
HFO Compatibility: Demonstrates excellent system stability when used in conjunction with modern HFO blowing agents.
-
Highly Blow-Selective: Effectively promotes the water-isocyanate blowing reaction with minimal cross-interference in premature gelation.
-
Cost-Effective Customization: Ideal for B2B clients requiring stable, long-term polyurethane additive supplies.
Suggested Applications & Use Levels
MXC-DMDEE is a versatile catalyst designed for broad industrial applications, integrating seamlessly into existing production lines:
-
One-Component Systems (OCF & Sealants): Ensures very long shelf life. Common use levels are 0.5% to 1.5% of the polyol blend.
-
Two-Component Formulations: Typical use levels range from 0.5 to 3.0 parts per 100 parts of polyol (php), depending on specific formulation requirements.
-
PIR Formulations: Can be utilized as a co-catalyst alongside trimerization catalysts (when low front-end activity is required).
Storage & Handling
-
Shelf Life: Minimum 12 months in unopened, factory-packed containers.
-
Optimum Temperature: Store in a dry and cool environment between 10°C and 30°C.
