How to Identify Genuine Kolor Kut Water Finding Paste
Counterfeit Kolor Kut Water Finding Paste has been identified circulating in the European market. It is packaged to closely resemble the genuine product, but differs in composition, performance and origin. Circonis sources Kolor Kut products exclusively direct from the manufacturer in the USA — every tube we sell is genuine. This guide explains how to tell the two apart.
Why Genuine Matters
This isn't just about getting what you paid for. In a safety-critical application, the difference between genuine and counterfeit paste has real consequences.
No Verifiable Safety Data Sheet
A counterfeit product comes with no verifiable Safety Data Sheet (SDS). Without an SDS, the actual chemical composition of what you're applying inside a fuel tank is unknown — it could include solvents, dyes or other substances that are unregulated, hazardous, or restricted under the EU's REACH chemical regulation. For a product used in aviation, marine and fuel-industry safety contexts, this isn't a minor quality concern — it's a genuine unknown risk to personnel, equipment and regulatory compliance.
Unverified Manufacturing Origin
Genuine Kolor Kut Water Finding Paste is manufactured in the USA by Kolor Kut Products Co. under the manufacturer's own quality control. The counterfeit product circulating in the European market originates from unverified production in China, with no traceable manufacturer, no accountable quality process, and no way to confirm what standards — if any — were followed during production.
Reaction Reliability
Genuine Kolor Kut paste reacts instantly and unambiguously on contact with water, producing a sharp, immediate colour change at the water interface. Counterfeit paste has been observed to react with a noticeable delay. In a safety-critical check — confirming a fuel tank is free of water contamination before an aircraft or vessel departs — a delayed or unreliable reaction defeats the entire purpose of the product, and could allow contaminated fuel to go undetected.
How to Tell Them Apart
Compare your product against these reference photos of confirmed genuine and counterfeit Kolor Kut Water Finding Paste.
Box & Tube Colour
Genuine tubes and boxes have a more vibrant, saturated colour. The counterfeit product is noticeably brighter and more washed-out by comparison. The counterfeit box also carries a labelling error — it reads "3OZS" instead of the correct "3 OZ".
Cap Seal
This one is counterintuitive: genuine Kolor Kut tubes do not have an internal seal under the cap. Counterfeit tubes do. Normally a seal signals authenticity — here it's the opposite, so don't assume the sealed tube is the genuine one.
Paste Colour
Genuine paste is a dark orange that transitions into brown. Counterfeit paste is distinctly pink — a clear visual difference once you know to look for it.
Tube Size
Side by side, the counterfeit tube is visibly smaller than the genuine tube.
Every Tube We Sell Is Genuine
Every Water Finding Paste we sell at Circonis is genuine, sourced directly from Kolor Kut Products Co. in the USA — never from third-party resellers or unverified supply chains.
