Glycols & glycol ethers
Glycols, polyglycols and their ethers and ether acetates — properties, grades and where each one fits in a formulation.
Application notes, material explainers and process guidance written around the chemicals we manufacture and export.
Propylene glycol against its neighbours: how to choose
Where propylene glycol is the right diol, where a neighbouring polyol does the job better, and how to argue a substitution on…
Where diethylene glycol comes from, and how it travels
Diethylene glycol is a co-product of ethylene glycol manufacture, so it exists in volume whether anyone orders it or not. Understanding where…
How TEG dehydration works: absorption and regeneration
Why a triol strips water out of gas, why the regenerator sets the ceiling on performance, and how to read a wet…
Qualifying DCAC as a tail solvent: a bench method
An all-round solvent is a claim about many systems at once. Here is how to test it in the one system that…
Diethylene glycol propyl ether: the homologue in between
Where the propyl homologue sits in the glycol ether series, and how to run a substitution trial that survives the first production…
Anti-blushing solvent: what the nickname really means
Two workshop nicknames for butyl glycol describe one mechanism. Here is the mechanism, and what it means when you specify.
Butyl diglycol as a coalescent in waterborne coatings
How a coalescent divides itself between water and polymer, why that division decides the film, and what stays behind afterwards.
Diethylene glycol monoethyl ether acetate explained
A slow ester-ether solvent for coatings, inks and personal care: what the structure buys, and the hydrolysis question that decides shelf life.
Butyl diglycol in printing inks: a working guide
Diethylene glycol monobutyl ether as an ink and cleaner solvent: what it does on press, how it differs from its neighbours, and…
DPMA in coatings: the solvent that leaves the film last
Dipropylene glycol methyl ether acetate is bought for what happens at the end of drying, not the beginning; here is how to…
