WHAT THE PRODUCT PHYSICALLY IS IN THE HAND - a liquid, a paste, a gel, an aerosol spray, a solid stick. Every house publishes it, inside the field it calls appearance or viscosity: Henkel's `Appearance (uncured): Black paste`, `Transparent, colorless to straw colored liquid`, `Clear to slightly cloudy gel`, and its `Viscosity: Thixotropic paste`; Permatex's `Appearance: Grey non-sag paste`; Sika's `Non-sag properties: Very good`; 3M's `mist` spray pattern for Super 77. It separates real products that agree on everything else: a brush-on liquid threadlocker and a gunnable paste sealant may share chemistry, cure and strength and are not interchangeable in a workshop. NOT REDUNDANT WITH `color` [A11], although the makers' own field packs both into one string: `Black paste` says black AND paste, and the two go to two slots. NOT REDUNDANT WITH `dynamic_viscosity` either - that is a measured number at a stated temperature, this is the qualitative class the maker sells on, and a thixotropic paste and a thin liquid can publish similar Brookfield figures at different spindle speeds. THIS SLOT ANSWERS THE QUEUE'S H7 QUESTION AND IS ON NOTICE BECAUSE OF IT. The queue asked whether the dispensing form of a maintenance chemical - aerosol, liquid, paste - is one slot shared with H5. IT IS THE SAME FACT, and an anti-rust spray and a carburettor cleaner will answer this property and not a second one. It is minted here rather than on `Product` because a spine change is not a kind proposal's call, and it LIFTS to a common parent under [L5] the moment H7 seeds a maintenance chemical, at which point `AdhesiveSealant` is re-tested under [L3]. That is the shape of H1-f6, H2-f7, H3-f5 and H4-f1, and it is written here so a later session cannot miss it. Distinct from the live `dispensing_mechanism`, which is how a grease gun drives its contents out - a fact about a tool, not about a substance. AN AEROSOL IS NOT A VALUE HERE and that is a ruling, not an omission: Soudal's Soudafoam Gun is a polyurethane FOAM supplied in a pressurised can, so consistency and package are two questions, and the pool already owns the second twice (`spray_mechanism`, `dispensing_mechanism`). UNSPSC agrees, filing `31201621 Aerosol adhesive` and `31201608 Foam adhesives` as two commodities of one class. The label `how it is supplied` was struck for the same reason - it is the packaging reading and this property holds the substance's consistency [A10]. Concern identity: a paste and a foam are two listings.
