Automotive and Transportation
Automotive coatings and interiors are where yellowing resistance, gloss retention and seat comfort are all judged by the end customer rather than by a laboratory.
What Goes Wrong in This Industry
Common Pain Points
- Refinish clearcoats that lose gloss or amber within a few years of outdoor exposure
- Seat foam that does not hold load bearing performance over the life of the vehicle
- OEM lines that cannot switch supplier without requalifying the whole coating stack
What We Supply Against Them
- Aliphatic HDI and IPDI based hardeners give light stable, non yellowing topcoats with high gloss retention
- TDI and MDI supply the flexible and moulded foams used in seating and interior components
- Grade level specifications let you match an incumbent product on NCO content and viscosity before trialling

Quality control across incoming materials, production and finished product inspection, with a batch certificate of analysis.
Packing And Documentation
Export packaging, specialised hazard packing for dangerous goods, and validated cold storage shippers where the material requires it.
Shipment
Sea, land or air routing coordinated through our Hong Kong entity. 20-30 days after the deposit is received.
Related Process Guides

A 2K polyurethane coating is a negotiation between pot life, dry speed, hardness and weathering. This is how we work through it with a formulator.
See The Process
Epoxy work is resin plus hardener plus cure schedule. Changing any one of the three changes the other two, so we specify them together.
See The Process
Cast elastomers, rollers and TPU all come down to three components: the isocyanate, the polyol soft segment and the chain extender.

Aromatic isocyanates are faster and cheaper. Aliphatic isocyanates keep their colour. This guide sets out which property actually decides the choice.
Read The Guide
Both are aliphatic HDI derivatives and both give light stable coatings. Their crosslink density, viscosity and flexibility are not the same.

Which products do you supply into automotive and transportation?
The products listed on this page: HDI Trimer Polyisocyanate Curing Agents, IPDI Trimer Polyisocyanate Curing Agents, HDI Hexamethylene-1,6-Diisocyanate, IPDI Isophorone Diisocyanate, TDI Toluene Diisocyanate, MDI Diphenylmethane Diisocyanate. Each one carries its full grade table on its own page.
Can you match a grade we already use?
Send the datasheet or the key figures — NCO content, equivalent weight, viscosity, solids — and we will say which of our grades matches and which do not. We will also say when nothing matches.
What volumes do you supply?
All international orders carry a minimum order quantity. Standard packing formats in this range are 200 kg steel drums and 1,000 kg IBC, with bulk supply available on request for regular volumes.
How long does a first order take?
Samples about 7 days. Mass production 20-30 days after the deposit is received, once your final approval is given.
Do you provide technical support during qualification?
Yes. We give product selection advice and formulation support based on your application requirements, processing conditions and performance targets.
