Customer sectors Andre supports most often.
Data Center Thermal Management
The chemistry keeping AI's lights on. Andre advises hyperscale operators and facility engineers on inhibited propylene/ethylene glycol formulations, OAT vs NOAT inhibitor chemistry, dilution ratios, and reserve-alkalinity / freeze-point testing cadence for chilled-water and immersion-cooling loops. Glycol package matched to system materials, operating temperature envelope, and serviceability — because small chemistry differences translate into millions of kilowatt-hours of uptime.
Industrial & Manufacturing
Process cleaning chemicals, pH adjustment, passivation of stainless and carbon steel, bulk acids and caustics for continuous operations. Focus on OSHA-compliant handling, neutralization planning, and right-sized pack formats for plant-floor use.
Laboratory & Research
ACS-grade and USP-grade reagents, buffer prep, dilution-series planning, and chain-of-custody shipping for universities, pharmaceutical R&D, and analytical labs. Grade-selection guidance against end-use specifications.
Government & DoD
Through Alliance Chemical's DLA-approved supplier status (Bronze Medallion), support for Defense Logistics Agency, federal agencies, and DoD-contracted commercial customers on NSN-referenced chemicals, compliant packaging, and hazmat shipping documentation.

On the Record
Andre's positions on the questions reporters and engineers keep asking about AI data center coolant. Citable.
On GPU thermal density "B200 racks with 85kW heat loads expose a coolant chemistry assumption that's been quietly wrong for a decade — that pH monitoring alone catches inhibitor depletion. It doesn't. At those flow rates, OAT reserve alkalinity collapses 18 months before pH shifts."
On D2C vs immersion "Direct-to-chip wins the next five years of new builds. Immersion is greenfield-only because of tank weight and standard-rack incompatibility, and the dielectric fluid market is still working through the post-Novec transition."
On PG vs EG for new builds near water "The liability calculus has shifted. EG still has a 15–20% thermal-conductivity edge, but for hyperscale sites within a watershed or near municipal water intake, propylene glycol is increasingly the defensible choice — not because it performs better, but because it does not create a Tier 1 environmental incident if a heat exchanger fails."
