Global Supply Chain and Sourcing
Regulated chemical raw materials are not hard to buy. They are hard to buy repeatedly, on time, with documentation that clears customs the first time.
Six Steps From Requirement to Delivered Material
This is the sequence we actually work through with a customer, not an idealised diagram.
Enquiry and Grade Confirmation
You send the performance target or an incumbent grade; we confirm what matches and what does not, within 24 hours.
Sampling
Free samples for laboratory testing and formulation validation, shipped in about 7 days with the buyer covering freight.
Quotation and Terms
Pricing against current market conditions, with 30% deposit in advance and 70% against a copy of the bill of lading.
Production and Quality Control
Quality control across incoming materials, production and finished product inspection, with OEM partners and specialised plants for customised grades.
Hazard Packing and Documentation
High quality export packaging, specialised hazard packing for dangerous goods and validated cold storage shippers for temperature sensitive items.
Multimodal Shipment
Sea, land and air shipments coordinated through the Hong Kong entity, with mass production delivery in 20-30 days after deposit.

Aromatic isocyanates are faster and cheaper. Aliphatic isocyanates keep their colour. This guide sets out which property actually decides the choice.

Both are aliphatic HDI derivatives and both give light stable coatings. Their crosslink density, viscosity and flexibility are not the same.

Read The GuideQuestions About This Process
Do you charge for this technical support?
No. Product selection advice and formulation support are part of supplying the material, based on your application requirements, processing conditions and performance targets.
Can you supply everything in this process from one order?
Yes, where the materials are in our range. That is the main reason buyers consolidate: one purchase order, one packing list, one shipment.
What if none of your grades fit?
We will say so. Customised grades are possible through our OEM partners and specialised manufacturing facilities, and where they are not, we would rather tell you than sell you the nearest thing.
How quickly can we start?
Samples for validation take about 7 days. Mass production is 20-30 days after the deposit is received.
What are the commercial terms?
30% deposit in advance, 70% against a copy of the bill of lading. Bank transfer, Xtransfer or PayPal. All international orders carry a minimum order quantity.
