Acidising is the application where an imidazoline earns its price and where it fails most expensively. A 15% or 28% hydrochloric acid job travels down N80 or P110 tubing at bottom-hole temperature, and the corrosion inhibitor is the only thing standing between the string and a corrosion rate measured in millimetres per year.

Two products, the same amino acid, and a price difference that makes the purchasing decision look obvious – until you do the arithmetic on delivered lysine. L-Lysine sulphate (CAS 60343-69-3) at 55% on a dry basis versus L-lysine HCl at 98.5% salt strength: the concentrations differ by a factor of about 1.4, and so does

Ask a swine nutritionist what limits performance in a maize-soy diet and the answer is usually one word: lysine. Ask a feed mill manager what they buy most of in the amino acid line and the answer is the same. L-Lysine sulphate (CAS 60343-69-3) is the volume product of that demand – a dried fermentation

Lysine is the first limiting amino acid in most cereal-based animal diets. That single fact drives one of the largest fermentation industries in the world – and it explains why there are two commercial forms of the same molecule: the purified hydrochloride and the concentrated fermentation product known as L-lysine sulphate (CAS 60343-69-3).

Produced water, desalter effluent and oily wastewater all carry the same problem in different forms: oil droplets and fine solids stabilised by negative surface charge, refusing to separate no matter how long you give them. Cationic polyamine is one of the standard tools for breaking that stability – and one of the most commonly misapplied.

Recycled fibre brought a problem into the paper mill that virgin pulp never had: a load of dissolved and colloidal anionic material that eats cationic additives before they reach the fibre. Retention aids fail, sizing does not hold, and the wet end becomes unstable. The industry’s answer is a low-viscosity cationic polyamine used as an

Seven grades of the same product, all “polyamine, light yellow liquid”, differing only in solid content and viscosity. To a purchasing department they look like a reason to buy the cheapest. To a plant chemist they are a selection variable that decides whether the coagulation programme works at all. This guide is about choosing between

Polyamine is one of those water treatment chemicals that is easy to buy and hard to buy well. Two suppliers can both quote “polyamine, 50% solids” and deliver materials that behave completely differently in a plant – because the property that actually matters is not the solid content but the charge density, and charge density

Every one-pack epoxy system is a trade-off between staying stable in the package and curing fast in the press. Dicyandiamide (DICY, CAS 461-58-5) sits at one end of that spectrum – the most latent, the most forgiving on storage, and the slowest to cure. The alternatives each move you along the same curve. This guide
Dicyandiamide vs Other Latent Curing Agents Read More »
A one-pack epoxy adhesive is a contradiction unless the curing agent refuses to react at room temperature. That is exactly what dicyandiamide does: it sits in the formulation as an inert filler-like solid, survives storage and extrusion, and only reacts when the part reaches 160-180 deg C. The whole one-pack adhesive, prepreg and laminate industry
