Product Description

TMI (CAS :2094-99-7) is a highly reactive unsaturated aliphatic isocyanate, a type of aliphatic diisocyanates, renowned for its exceptional chemical stability, robust adhesion, and superior resistance to weathering. These properties make it an industry-leading choice for advanced applications in coatings, adhesives, foam materials, and sealants. TMI’s unique unsaturated structure enables rapid reactions with diverse resins and polymers, forming high-performance crosslinked materials with enhanced durability and versatility.

 

Chemical and Physical Properties

 

1.  Molecular Structure: TMI (CAS:2094-99-7) features reactive isocyanate (-NCO) groups and an unsaturated bond, enabling dual functionality for copolymerization and crosslinking.
2. Appearance: Transparent to pale yellow viscous liquid with excellent fluidity for easy handling and integration into formulations.
3.  Reactivity: Maintains stable performance at room temperature but reacts rapidly with water, alcohols, and amines under controlled conditions to produce high-quality polyureas/polyurethanes.
4.  Chemical Resistance: TMI-modified polymers exhibit outstanding resistance to solvents, acids, and bases, ensuring longevity in harsh environments.

Applications

 

1.  Polymer Modification: TMI (CAS:2094-99-7) acts as a multifunctional additive for grafting NCO groups onto polymers. It copolymerizes with monomers like acrylates to create crosslinkable resins for coatings and adhesives.
2.  Coatings: Used in blocked acrylic copolymers for 1K acid-etch-resistant automotive topcoats and unblocked systems for ambient-cure industrial paints.
3.  Plastic Modification: Enhances surface adhesion of PP/TPO in automotive and packaging industries via grafting.
4.  Foaming Materials: Serves as a polyol dispersant additive, improving foam uniformity and mechanical properties.
5.  End-capping Agent: TMI’s unsaturated NCO is ideal for end-capping polyimide (PI) films, boosting thermal and chemical resistance.

 

Packing & Storage

 

TMI (CAS:2094-99-7) is supplied in 170 kg sealed drums and has a 12-month shelf life when stored in a cool, dry, moisture-free environment.
