## Identity and boundaries

ITW describes **HDP-Pro** as water-based. FUCHS **RENOFORM SVO 453** uses an evaporating base oil and an extreme-pressure additive. The carrier’s evaporation does not establish the absence of a residual additive film. The products have different supplied forms. [ITW product description][hdp-page] [FUCHS US product description][svo]

Use the stated grade and sample basis for properties. A water-containing mixture and a used fluid can differ from the supplied concentrate.

Stamping and drawing terminology overlaps. N 22-3 is described for both. This does not qualify every drawing fluid or machining coolant for stamping. [N 22-3 data sheet][n22]. See the separate [drawing-lubricant reference](drawing-lubricants.md) for drawing-specific product forms.

## Carrier, lubricant, and film

| Form | Source-supported example and distinction |
| --- | --- |
| Evaporative or vanishing liquid | RENOFORM SVO 453 has an evaporating base oil and an extreme-pressure additive. The carrier and lubricating package have different roles. [FUCHS][svo]. |
| Non-water-soluble prelube | N 22-3 is described as thixotropic and leaves an oily film. It is not a dry-film example. [Master Fluid Solutions][n22]. |
| Water-miscible product | VS-HSS is a semi-synthetic micro-emulsion lubricant for progressive dies and multiple forming operations with high-strength steel. [ITW product description][vs-page]. |
| Dry film on sheet | Chemcoaters describes waterborne DFL coatings that form temporary, hard, dry-to-touch lubricating films. It separately describes permanent InterCoat ChemGuard films for galvanized materials. These are range-level descriptions. [Chemcoaters][dfl]. |

**Synthesis.** "Dry film" describes the film on the metal, not necessarily the physical form of the supplied material. A waterborne coating can produce a dry film. A vanishing carrier can leave lubricant behind. "Synthetic" and "semi-synthetic" do not disclose ingredient percentages or establish equivalent performance.

Klüber's UK page identifies Klübertec ST 4-701, article 046067, as ester oil with aliphatic hydrocarbons. It states that solvent constitutes 90%, without specifying a mass or volume basis. The page links solvent evaporation with downstream welding, bonding, and painting being unaffected "in most cases". That qualification excludes a universal compatibility guarantee. The remaining percentage cannot be assigned entirely to ester oil or active lubricant from this description. Its product information and SDS downloads require login and were not evaluated. [Klüber product description][kluber].

## Exact-product liquid properties

These values describe supplied products in European English WEDOLiT sheets. The producer labels them typical data. Density and viscosity use ASTM D 7042. Flash point uses DIN EN ISO 2719. Method editions are unspecified. [FS 4512][fs]; [N 22-3][n22].

| Supplied product | Stated material and role | Kinematic viscosity | Density | Flash point |
| --- | --- | --- | --- | --- |
| WEDOLiT FS 4512 | Solvent-based liquid for punching and bending steel, aluminum, and non-ferrous metals | 2.6 mm²/s at 20 °C | 0.77 g/cm³ at 20 °C | >62 °C |
| WEDOLiT N 22-3 | Prelube for coated carbon steel, including zinc-, zinc-nickel-, and aluminum-coated sheet. Also described for aluminum and its alloys. | 120.0 mm²/s at 40 °C | 0.91 g/cm³ at 15 °C | >190 °C |

FS 4512 lists copper corrosion as undetermined. Its footnote flags possible non-ferrous-metal discoloration. Its low-residue statement depends on fine distribution and says almost no residue, rather than zero. It provides no measured evaporation rate, residue mass, or matched wear-test result. [FS 4512 complete sheet][fs].

N 22-3 reports fulfilled removability under VW-52.01/VDA 230-201 at 1.7 g/m², an analytical film loading, not a coating prescription. It describes phosphating after grease removal, without universal paint-adhesion or weld-quality results. [N 22-3 complete sheet][n22].

## Water-miscible examples and unresolved data

ITW's VS-HSS sheet addresses light- to medium-duty high-strength-steel frame components. It prints specific gravity twice, as 0.99 and 0.95, without resolving the conflict or giving reference temperatures. Its density entry is 8.4 lb/gal with 1010 kg/m³ alongside. The gallon basis is unspecified. The flash point is >200 °F, with >93 °C alongside, but no method appears. Neither value repairs the conflicting specific gravities. [VS-HSS sheet][vs-tds].

The sheet's "Total Chlorine" entry says "None", without an analytical method or detection limit. Its claim that cleaning before welding is unnecessary has no published welding procedure or acceptance test. The claim concerns this product's stated application and does not qualify every weld. The sheet also disagrees internally on color, listing blue in properties and creamy white in packaging. [VS-HSS sheet][vs-tds].

HDP-Pro is a separate severe-duty example. Its sheet identifies heavy-gauge steel, ultra-high-strength steel, and stainless steel. It lists specific gravity 1.02 without reference temperatures, and flash point >93.0 °C by Pensky-Martens closed cup. Viscosity and evaporation rate are unavailable. Its VOC value is 0 g/L explicitly for concentrate, with no method or regulatory definition provided. No active-content or solids value is supplied. These omissions prevent a viscosity or lubricating-solids ranking against the other examples. [HDP-Pro sheet][hdp-tds].

## Disclosed ingredients are not a formula

HDP Pro Metal Stamping Fluid's US English SDS, version 01 issued June 20, 2023, covers MM3402, MM3403, and MM3406. Section 3 reports the following bands. Its column is labeled `%` without specifying mass or volume. These entries therefore remain printed percentages rather than independently established weight percentages. [SDS, pages 1–2][hdp-sds].

| Disclosed identity | CAS number | Printed percentage band |
| --- | --- | --- |
| Triethanolamine | 102-71-6 | 5–10% |
| 3-amino-4-octanol | 1001354-72-8 | 1–3% |
| Diethylene glycol | 111-46-6 | 1–3% |
| Poly(oxy-1,2-ethanediyl), alpha-(carboxymethyl)-omega-(9-octadecenyloxy)-, (Z)- | 57635-48-0 | 1–3% |
| Other components below reportable levels | Not individually identified | 88 to <89% |

The unidentified band is not declared water, oil, or active lubricant. Independent interval endpoints do not reconstruct a mass-balanced formula. The SDS identifies serious eye damage and skin sensitization hazards. Neither water-based identity nor zero stated concentrate VOC establishes absence of hazards. Its viscosity remains unavailable, and its composition is not a current-lot assay. [HDP-Pro SDS][hdp-sds].

FUCHS calls SVO 453 free of chlorine, sulfur, and fat. That exact-product statement provides no phosphorus-free claim, complete ingredient list, or detection-limit evidence. Its extreme-pressure additive is not chemically identified. The US page also states that performance depends on application and environment and disclaims universal suitability. [FUCHS SVO 453][svo].

## Units and conditional deductions

**Synthesis.** Kinematic viscosity in mm²/s, also called cSt, differs from dynamic viscosity in mPa·s. ASTM's public D7042-25e1 scope relates these quantities through density measured at the same temperature. Its stated applicability is primarily Newtonian liquids, and published precision is limited to identified materials and conditions. The product's thixotropic description does not establish a complete viscosity model. [ASTM public scope][astm]. The two WEDOLiT viscosity results use different temperatures, so their numerical ratio is not a matched-temperature comparison. N 22-3's density at 15 °C cannot supply its exact dynamic viscosity at 40 °C.

Density is mass per volume. Specific gravity is a dimensionless density ratio whose reference conditions matter. A bare specific gravity cannot become a measured g/cm³ value without assumptions. A flash-point lower bound is not a boiling point, evaporation rate, or permissible process temperature.

Mass percentage and volume percentage have different denominators. Residual-film mass, total solids, and lubricating active content describe different quantities. None is established by a product's name, color, or VOC entry. The reviewed evidence supports no manufacturing formula or operating recipe.

## Applicability and source limits

**Synthesis.** Tool life, friction, finish, corrosion protection, and formability claims depend on the sheet alloy, coating, tool, and test conditions. The reviewed sources do not provide a matched comparative stamping trial. The descriptions therefore support intended roles, not a universal performance ranking. Downstream cleaning, welding, painting, and bonding claims are product statements rather than customer qualification.

The review date is 2026-10-30 PDT. Both WEDOLiT PDFs were retrieved directly and read in full, including property tables, footnotes, sidebars, and disclaimers. Their retrieved footers display October 30, 2026. These footer dates do not establish a formulation revision. European English literature does not prove equivalence to a product sold elsewhere. [FS 4512][fs]; [N 22-3][n22].

The complete one-page VS-HSS and two-page HDP-Pro sheets are undated and have no visible revision identifiers. The complete seven-page HDP-Pro SDS has the explicit 2023 version above. Current hosting does not establish that it describes today's delivered lot. The ITW product pages, FUCHS US page, Klüber UK page, and Chemcoaters range page have no technical revision identifiers. Only ASTM's public scope was evaluated, without paid standard text. No matched SDS was evaluated for the other named grades. No lot certificate, complete formulation, quantified dry-film composition, or customer-specific approval is established.
