Ethanolamines
MEA, DEA, TEA and DGA — supplied against a named specification, with the fill date and packing condition confirmed before dispatch.
- Grades
- Standard commercial grades; low-freeze and higher-purity lots on enquiry.
- Packing
- Drums, IBCs and ISO tanks, with nitrogen blanketing where the specification calls for it.
- Handling
- Hygroscopic and colour-sensitive. Storage guidance is supplied with the safety data sheet.
- Repeat volume
- Call-off schedules held against an agreed price rather than re-quoted each shipment.
What usually goes wrong
Ethanolamines discolour with air and moisture, and colour is usually the first thing incoming QC looks at. A lot can leave the producer on specification and arrive off it because of how long it sat, in what, and whether the headspace was blanketed. The certificate that came with the original production run tells you nothing about the drum in front of you.
How we handle it
We confirm the fill date and the packing condition before dispatch and supply the certificate of analysis for the batch delivered, not a typical-value sheet. If you test to a colour specification, tell us the limit and we will quote against it rather than around it.
