Lubinpla Technical Research
Analysis for specialists who work with specialty chemicals: mechanisms, decision frameworks, case analyses, document guides, regulatory change and test methods, written from primary sources.
Mechanisms
How failures and reactions happen, and the conditions that change them.

Turbine oil varnish: why it forms while antioxidants remain
Varnish forms when degradation products from hot spots, micro-dieseling or static discharge exceed oil solvency, even with antioxidants left. Here is how.
-
Moisture in transformer paper and oil: how temperature moves it
Warming pushes water from transformer paper into oil and cooling pulls it back slowly, so an oil moisture result shows paper moisture only at equilibrium.
Decision Frameworks
Criteria for technical decisions, laid out so they can be applied to a specific case.
-
How to Decide When a Safety Data Sheet Needs Revision
To decide if an SDS needs revision, check classification, exposure limits and risk measures against the OSHA and REACH triggers. See the criteria.

Replace or Re-Inhibit Loop Glycol? How to Decide From Fluid Tests
Decide whether to replace or re-inhibit closed loop glycol by checking reserve alkalinity, pH, glycol percent, metals and microbes against supplier limits.
Case Analyses
Analyses of published cases and what they show.
-
Ester Fluid Failure: How a Hydrostatic Pump Loss Was Traced
A 300 kW ester hydrostatic drive lost its pumps in 12 months. How the published case traced it to loop overheating and fluid oxidation, and what to check.
Document Guides
How to write and check technical documents such as specifications and approval requests.
-
How to Answer a Customer PFAS Questionnaire Without Overstating
A PFAS questionnaire answer needs five sections: products covered, PFAS definition, intentional-use statement, evidence and its limits, and a review date.
-
How to Write a Closed Loop Water Treatment Report Owners Act On
A closed loop water treatment report needs sampling details, results against limits, trends, a diagnosis and owned actions. Structure and a checklist.
Regulatory Change
What a change in a standard or regulation means for products, what to do and by when.
-
Stockholm PCB deadlines 2025 and 2028: what they mean for oil
Stockholm Convention parties aimed to end PCB equipment use by 2025 and manage PCB liquids soundly by 2028. What owners of transformer oil must do now.
-
TSCA PIP (3:1) Rule: What It Means for Phosphate Ester Fluids
Under TSCA, PIP (3:1) hydraulic fluids are allowed only for aviation or military-spec uses. What the 2025 revision changed and what fluid users do now.
Test Methods
What a test measures, which edition applies and how to read the result.
-
ASTM D7843 MPC varnish test: what it tells you and what not
ASTM D7843 MPC reports varnish potential as Delta E, not deposits already in the system. Read results with temperature history, RULER and RPVOT trends.

FZG Scuffing Test ISO 14635-1: What It Tells You About Gear Oil
ISO 14635-1:2023 (FZG A/8.3/90) finds the load stage at which an oil lets test gears scuff: a relative scuffing ranking, not field life. How to read it.
