How Ester Alcohol Coalescents Work in Latex Paint: MFFT and Film Formation

Coatings & Additives /

Every latex paint formulator knows the frustration: the paint looks perfect in the lab but cracks and powders when applied on a cold wall. The culprit is the minimum film-forming temperature (MFFT), and the solution is a coalescent — most commonly the ester alcohol coalescent known commercially as Texanol (CAS 25265-77-4). This article explains the […]

Xanthate Safety: Handling, Storage and Decomposition of SIPX

Mining & Flotation Reagents /

Xanthates are effective flotation collectors, but they carry a specific set of hazards that every buyer, warehouse manager and plant operator must respect: decomposition to carbon disulfide (CS2), combustible dust, and moisture sensitivity. This guide covers the safety, storage and handling of xanthates such as sodium isopropyl xanthate (SIPX, CAS 140-93-2) — the practical rules

SEX vs SIPX: Ethyl vs Isopropyl Xanthate

Mining & Flotation Reagents /

Ethyl xanthate (SEX) and isopropyl xanthate (SIPX) are the two most common short-chain xanthate collectors in sulfide flotation. They look similar — both are pale yellow sodium xanthates — but the one-carbon difference in their alkyl chains changes collecting strength, selectivity and cost. This article compares SEX and SIPX so mill operators can choose the

SIPX in Copper and Lead-Zinc Flotation: Dosage and Circuit Practice

Mining & Flotation Reagents /

Sodium isopropyl xanthate (SIPX, CAS 140-93-2) is the most widely used flotation collector for copper, lead and zinc sulfide ores. But “widely used” does not mean “used the same way everywhere” — the dose, the circuit position and the combination with other reagents change with ore type, mineralogy and water chemistry. This article covers practical

How to Buy PolyDADMAC: Specs, COA and Grade Selection

Water Treatment Chemicals /

PolyDADMAC (polydiallyldimethylammonium chloride, CAS 26062-79-3) is a liquid cationic polymer sold in a range of solids contents, viscosities and purity grades. Because it has no single “purity” number, buyers often struggle to compare quotes. This purchasing guide covers the specification sheet, the COA, packaging and storage, and the supplier checklist for PolyDADMAC. 1. Reading the

PolyDADMAC in Papermaking: Anionic Trash Catcher and Retention

Water Treatment Chemicals /

In the paper mill, the wet end is a constant chemical balancing act: fibers, fines, fillers and dissolved anionic substances all compete for retention, drainage and cleanliness. PolyDADMAC (polydiallyldimethylammonium chloride, CAS 26062-79-3) is one of the most widely used cationic polymers in papermaking — as an anionic trash catcher (ATC), a retention aid component, and
