AdhesiveAdditives.com compiles every fact on adhesive chemicals from the body that issued it, labels each value as a requirement, a typical product value or a published estimate, and dates it. Seven kinds of named primary source feed the pages, from ECHA, EUR-Lex and eCFR to ISO, CEN and ASTM, peer-reviewed journals and dated producer data sheets.
The AdhesiveAdditives.com Editorial Team compiles and checks every page and is named as its author; no page names a person as author or reviewer. Below are the sources that decide each fact, the five checks before publication, the rule for unconfirmed facts, and how pages are dated and corrected.
What Sources Does AdhesiveAdditives.com Use?#
AdhesiveAdditives.com draws on seven kinds of source, from EU and US regulators and official chemical registers to standards bodies, peer-reviewed journals, producer data sheets and dated trade publications, and cites each fact to the body that issued it. A data sheet never settles a legal question, and a regulation never supplies a grade value. The table below compares the seven source kinds by issuing body, the facts each decides and where those facts appear.
| Source kind | Issuing bodies | What it decides on this site | Where it shows |
|---|---|---|---|
| EU law and EU agencies | EUR-Lex, ECHA | regulations, annexes, dates of application, CLP classification | adhesive regulation |
| Substance registers | ECHA CHEM, PubChem | CAS number, EC or ECHA list number, structure | adhesive substances |
| US federal and state rules | eCFR, FDA, EPA, OSHA, NIOSH, OEHHA, SCAQMD, CARB | food-contact listings, TSCA, exposure limits, Prop 65, VOC limits | on each page that cites them |
| Standards bodies | ISO, CEN, ASTM, FINAT, PSTC | test methods, classes, editions and status | adhesive standards |
| Peer-reviewed literature | journals and scientific handbooks | mechanisms, measured results | adhesion science |
| Producer technical and safety data sheets | the producer of the named grade | typical product values with grade and date; product hazard data | adhesive raw materials |
| Trade and analyst publications | the named publisher, for example ASI magazine | market estimates and rankings, quoted as the publisher's with scope and year | adhesives market estimates |
Regulators, Official Registers and Standards Bodies#
Official texts decide legal and identity facts: EUR-Lex for EU law, ECHA for EC numbers and CLP classification, PubChem for CAS numbers and structures, and eCFR or the issuing agency for US rules.
A newer official text beats any earlier summary of it, including one on this site. Standards are cited from the catalogue of the body that publishes them, such as ASTM, ISO or CEN. Copies of standards posted without the publisher's permission and Wikipedia are never sources.
Peer-Reviewed Literature and Producer Data Sheets#
Peer-reviewed papers explain mechanisms and measured results; a producer's technical data sheet describes only its own grade on its own date. A paper is cited by researcher, journal and year inside the sentence that uses it.
A data sheet never overrides a standard or a regulation. A safety data sheet is named as the source for that product's own hazard data, never for a substance classification. Loadings always carry their basis, such as wt % of formulation, phr or parts per 100 resin.
How Is Each Fact Checked Before Publication?#
Each fact is read in the document that issued it, then receives a label, an edition or date, SI units with US customary units in brackets and, for a substance, its identity and hazard line. The five checks before publication are listed below.
- Issuing document: the source itself, never a summary of it.
- Value label: requirement, typical product value or published estimate.
- Edition or date: of the standard, rule or data sheet.
- Units: SI first, US customary in brackets.
- Identity and hazard line: for every substance named with a CAS number.
Which label, then, does a number receive?
Three Labels for Every Value: Requirement, Typical Product Value, Published Estimate#
A requirement comes from a standard or rule, a typical product value from a named grade's data sheet with its date, and a published estimate from an analyst or trade publisher with scope and year; the three are never mixed. The label tells a formulator whether a number is a limit, one product's value or a publisher's view. The table below compares the three labels with one example each.
| Label | Where it comes from | How it is written | Example |
|---|---|---|---|
| Requirement | a standard or a rule | instrument or standard, section, edition or date | 21 CFR 175.105(a)(2)(i): the quantity of adhesive that contacts packaged dry food does not exceed the limits of good manufacturing practice |
| Typical product value | one named grade's data sheet | value, grade, producer, data sheet date | Escorez 5415 sales specification, ring-and-ball softening point 115.0 to 121.0 °C (239 to 250 °F), ExxonMobil, 9 February 2021 |
| Published estimate | an analyst or trade publisher | publisher, scope, year; never merged with another publisher's figure | ASI Top 20 2026, published by Adhesives & Sealants Industry magazine on 7 July 2026, ranks finished adhesive and sealant manufacturers by sales; quoted as ASI's ranking |
One grade's value is never written as the range of its class. A class range appears only where two or more producers' data sheets support it, with both sources named.
Test Standard Editions, Dates and Units#
Every standard is cited with its full designation, edition and status, for example ASTM D3330/D3330M-04(2025), active, and ISO 29862:2024. Both are 180° peel adhesion methods for pressure-sensitive tape, and both editions are cited in the same form on the page on peel adhesion testing. The year in brackets after an ASTM number is the year of its latest reapproval.
A withdrawn method is written as "withdrawn, still cited on data sheets", never as a current test. Dates in prose read day, month, year, such as 7 July 2026. Units are SI first with an exact conversion in brackets: °C (°F), mPa·s (cP), MPa (psi) and N/25 mm (lbf/in).
Hazard Classifications and Substance Identity#
A hazard line states the CLP Annex VI entry with its index number where one exists; otherwise it states "No Annex VI entry" with the majority ECHA notified classification. A notified classification is never called harmonized, and the hazard line is the starting point for hazard labeling, never derived from one safety data sheet.
Rosin (CAS 8050-09-7) carries CLP Annex VI 650-015-00-7 Skin Sens. 1 H317. Liquid epoxy resin (CAS 25068-38-6, EC 500-033-5) carries CLP Annex VI 603-074-00-8 Skin Irrit. 2 H315, Eye Irrit. 2 H319, Skin Sens. 1 H317 and Aquatic Chronic 2 H411. How these lines become label elements on an adhesive is covered under hazard labeling for adhesives.
CAS numbers carry their hyphens, and an EC number is written only where ECHA lists one; otherwise the page writes "ECHA list number", as for C5 hydrocarbon resin (CAS 26813-14-9, ECHA list number 608-001-3). Polymers and UVCB substances get no single formula. Clashing abbreviations are spelled out at first use: PVAc (polyvinyl acetate) and PVOH (polyvinyl alcohol), never a bare "PVA". A pending classification process is written as a dated process, never as a classification, and a classification that applies from a future date carries that date.
What Stays Unpublished Until It Is Verified?#
A fact that could not be confirmed in the issuing body's own text stays off the page: it is not hedged, not attributed to a secondary source and not replaced by an estimate. A standard edition the publisher's catalogue does not confirm is named only through the source that cites it.
Food-contact wording shows the rule at work. A page names the jurisdiction, the listing and its condition of use, never a general clearance: under 21 CFR 175.105, listed adhesive components are separated from food by a functional barrier or, for fatty and aqueous food, limited to the trace amount at seams and at the edge exposure between packaging laminates.
How Pages Are Dated, Updated and Corrected#
Every regulatory, standard and company fact on AdhesiveAdditives.com carries its own date, the edition of a standard, the date a rule applies or the date of a company event, and a page is reviewed when one of those sources changes. A company fact is written with the date of its event: the adhesive resins business of Eastman has belonged to Synthomer since 1 April 2022, when the acquisition was completed.
A review starts with CLP adaptations to technical progress, Candidate List updates, Annex XIV and XVII amendments, eCFR changes, SCAQMD Rule 1168 amendments, ASTM reapprovals and withdrawals, ISO and CEN revisions, completed acquisitions and the yearly ASI ranking. Reader corrections follow the same path; the full rules for corrections and disclosure are set out in the editorial policy on corrections.
A correction replaces the wrong value in place, and the modified date of the page changes with it. No response or correction time is promised.
How to Report an Error#
To report an error, send the page URL, the statement and the source that shows the correct value; the Editorial Team checks it against that source. The three kinds of source that settle a report are listed below.
- Register entries: an ECHA CHEM or PubChem record for identity and classification.
- Current editions: the publisher's catalogue entry for a standard.
- Newer data sheets: a later data sheet for the same named grade.
Error reports reach the Editorial Team by email at editorial@adhesiveadditives.com or through the contact form.
