Description :

Overview of Hexamethylene Diisocyanate

Hexamethylene Diisocyanate, commonly known as HDI, is an aliphatic diisocyanate widely used in the production of high-performance polyurethane systems. It is valued for its excellent weather resistance, low yellowing tendency, and ability to produce durable, flexible, and chemically resistant materials.

For non-technical buyers, Hexamethylene Diisocyanate can be understood as a core raw material used to manufacture premium coatings, adhesives, and elastomers that need to perform well in outdoor and demanding industrial environments. Compared to aromatic diisocyanates, HDI offers superior colour stability and long-term durability.

Hexamethylene Diisocyanate is classified under aliphatic diisocyanates and polyurethane raw materials, supporting advanced coating, adhesive, and elastomer technologies.

Applications of Hexamethylene Diisocyanate

Polyurethane Coatings & Protective Finishes

Hexamethylene Diisocyanate is extensively used in polyurethane coatings for automotive, industrial, and architectural applications. It provides excellent UV resistance, gloss retention, and mechanical strength, making it ideal for exterior coatings.

Adhesives & Sealant Systems

In adhesive and sealant formulations, Hexamethylene Diisocyanate contributes to strong bonding, flexibility, and resistance to moisture and chemicals. It is commonly used in structural and industrial adhesive systems.

Elastomers & Industrial Components

Hexamethylene Diisocyanate is used in the manufacture of polyurethane elastomers for rollers, seals, gaskets, and moulded industrial components. These elastomers offer high abrasion resistance and long service life.

Speciality Resins & Prepolymers

HDI is also used to produce polyurethane prepolymers and speciality resins. It supports controlled curing behaviour and consistent performance in advanced polymer formulations, often used alongside materials such as Polyurethane Resin and Isophorone Diisocyanate.

Safety & Handling Guidelines

• Store in a cool, dry, and well-ventilated area

• Keep containers tightly sealed and protected from moisture

• Avoid inhalation of vapours and aerosols

• Prevent direct contact with skin and eyes

• Use protective gloves, goggles, and suitable industrial clothing

• Handle only with appropriate isocyanate safety precautions

• Keep away from water, alcohols, and reactive chemicals

• Dispose of packaging according to local regulatory guidelines
