Sources & Image Information
Understand the sources behind technical content and the distinction between reference images and company facts.
Public technical information
Sources support chemical-identity, treatment-option, application-condition and purchasing checks. Third-party documents are not ENVO certificates, product approvals or project records. Historical documents are retained only as relevant technical references.

Image use
Product pages distinguish appearance references, packaging-design references and illustrative application scenes. Product identity illustrations are used where a product photograph is unavailable for publication. Application images illustrate environments; they do not represent ENVO-owned facilities or completed projects.
