Key Advantages
- Exceptional Storage Stability: Features a sterically hindered structure; does not react with NCO groups at room temperature, allowing single-component formulations to be stored for 6–12 months.
- Moisture-Triggered Curing: Catalyzes the reaction between NCO groups and water only upon exposure to atmospheric moisture, thereby initiating foaming and crosslinking.
- Low Odor, Low VOC: Possesses a significantly milder odor compared to conventional amine catalysts (e.g., DABCO).
- High Foaming Efficiency: Promotes the generation of CO₂, resulting in high expansion ratios and low foam density.
- Excellent Compatibility: Miscible with polyether and polyester polyols, isocyanates, and most common additives.
Known Application
A moisture-curing catalyst specifically designed for one-component polyurethane (1K PU) systems, balancing “long-term storage stability” with “rapid curing/foaming upon contact with moisture.”
1) One-Component Polyurethane Foams (Primary Application)
Building Insulation: Spray-applied rigid foam for walls, insulation layers for cold storage/refrigerators, pipe insulation.
Filling/Sealing: Foam sealants for doors and windows, injection grouts for wall cracks, leak-sealing for tunnels and underground structures.
Features: With the addition of DMDEE, the packaged material can be stored for 6–12 months without gelling; during application, it foams and cures rapidly upon contact with moisture, producing a uniform cell structure with minimal shrinkage.
2) One-Component Sealants and Adhesives (1K PU Adhesives)
Construction: Structural sealants for curtain walls, weather-resistant sealants, concrete joint sealants.
Automotive: Windshield adhesives, body seam sealants, interior trim bonding.
Industrial: Pipe sealing, equipment flange sealing, container sealants.
Features: Does not compromise shelf life; offers rapid tack-free time, excellent deep-section curing, and strong adhesion; low odor, making it suitable for indoor and automotive interior applications.
3) One-Component Elastomers and Coatings (1K PU Coatings/Elastomers)
Running Tracks/Flooring: Polyurethane running tracks, sports court flooring, elastic flooring systems.
Synthetic/Artificial Leather: 1K PU resins for synthetic leather, surface treatment agents for artificial leather.
Waterproofing Coatings: PU waterproofing coatings for roofs and basements, anti-corrosion coatings for bridges.
Features: Promotes moisture-induced crosslinking, resulting in a tough, abrasion-resistant, and water-resistant film; does not compromise the shelf life of the coating.
4) Two-Component PU (Auxiliary Application)
Acts as an auxiliary foaming catalyst in flexible foams, semi-rigid foams, and CASE materials (Coatings, Adhesives, Sealants, Elastomers); used in conjunction with DABCO and organotin catalysts to balance the rates of foaming and gelling.
