Aliphatic Polyisocyanate Supplier in Malaysia
Aliphatic polyisocyanate is a family of reactive crosslinkers supplied for polyurethane coatings and related formulations in Malaysia. Coatings buyers also describe these materials as polyisocyanate hardeners or isocyanate hardeners, while the required chemistry is defined more precisely by structure and grade.
The family includes HDI trimer, HDI biuret, water-dispersible, blocked and other grade-specific structures. These are separate family members rather than interchangeable aliases, and buyers should specify NCO content, solids, viscosity, free monomer limit, solvent system and resin compatibility where applicable.
Applications include automotive clearcoats, industrial and protective coatings, wood finishes, coil and plastic coatings, adhesives, sealants, printing inks and selected polyurethane elastomer systems. Aliphatic types are distinct from aromatic MDI and TDI products and should not be substituted without formulation assessment.
Send the required structure, specification, quantity, application and delivery location for a quotation. Availability, packing, documentation, delivery timing and quotation validity are confirmed for the selected grade, and supply is subject to applicable requirements.

Aliphatic Polyisocyanate applications
Common questions about aliphatic polyisocyanate
What is an aliphatic polyisocyanate used for?
It is used as a reactive crosslinker or polyisocyanate hardener in polyurethane coatings, adhesives, sealants, inks and elastomer systems. The correct grade depends on the companion resin and cure process.
Are HDI trimer and HDI biuret the same grade?
No. They are different aliphatic polyisocyanate structures with different specification and formulation profiles, so the required structure should be stated in the enquiry.
Is aliphatic polyisocyanate the same as polymeric MDI?
No. Polymeric MDI is aromatic, while this page covers aliphatic polyisocyanates based mainly on HDI or IPDI chemistry for different coating and crosslinking requirements.
Which specification details should I provide?
State the required structure, NCO content, solids, viscosity, free monomer limit, solvent or water-dispersibility requirement and compatible resin system. A matching grade can then be considered for quotation.
Are all aliphatic polyisocyanates solvent-borne liquids?
No. The family includes neat and solvent-borne liquids, water-dispersible grades and blocked types supplied in forms selected for the intended coating or cure system.
What is needed for a quotation?
Provide the complete grade specification, quantity, application and delivery location. Packing, documentation, availability and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.
