11 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.
Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.

This material’s published information has not yet been verified by a human reviewer.
Human verification concerns the stated information and scope. It is separate from an EcoSafe score, certification or safety approval.OSHA identity and chemical data ↗ · Sigma-Aldrich example: mixture of isomers ↗
H₁₂MDI is a reactive building block for light-stable polyurethane systems. Evonik describes applications in elastomers, polyurethane dispersions and radiation-curable urethane acrylates, with coating and paint-protection-film uses.
Specific spray-polyurea recipes and optical performance claims have not been verified for this generic record. It is not a ready-to-use formulation or a drop-in substitute for another diisocyanate.
Evonik product information and applications ↗
OSHA describes a clear, colorless to light-yellow liquid. Commercial isomer distribution, purity and physical properties depend on the supplier grade. Review inhalation, skin, eye and sensitization hazards using current product documentation.
NIOSH chemical hazard reference ↗
TDS: Evonik VESTANAT H12MDI product and document portal ↗. Checked November 2, 2026. The portal lists an English EMEA TDS requiring login; the previously indexed direct PDF URL returned 404. Obtain the current document for the exact purchased grade.
SDS: matching manufacturer document pending. Manufacturing origin: not yet verified; a supplier address or regional document label is not evidence of production country.
This record does not yet count toward the complete SDS/TDS-and-origin milestone.
Sources checked November 1, 2026. Identity checked against OSHA and the supplied Sigma-Aldrich page; application summary based on Evonik. No EcoSafe score or approval assigned.
