MDEA as a Co-Initiator in UV Coatings and Inks

A coatings buyer requests N-methyldiethanolamine (MDEA, CAS 105-59-9) for a formulation trial. Before selecting the grade, clarify the intended function. MDEA has uses in neutralization and in certain photoinitiator combinations, and the application team needs different performance checks for each role.

Define the co-initiator requirement

BASF identifies MDEA as a co-initiator for Type II photoinitiator combinations in coatings and inks. Its product information also describes separate uses as a neutralizing agent. Include the intended function in the sample request so the evaluation addresses the correct formulation requirement. CAS No. 105-59-9 |

For a co-initiator trial, identify the photoinitiator and resin system under review, together with the reference formulation.

Keep the curing conditions with the trial record

Have the application team define the addition levels and evaluation procedure. Record the light-source type, exposure conditions, film thickness, substrate and sample preparation alongside the formulation identity.

Use consistent conditions for reference and trial samples. This helps the team assess how the proposed MDEA grade performs within the selected system.

Evaluate the finished coating or ink

Set acceptance criteria before testing. Depending on the application, the review may include surface cure, hardness, adhesion, appearance, color and storage stability.

Record the MDEA grade, lot number and available quality data with the results. If a trial is approved, those records provide the starting point for commercial purchase specifications and batch documentation.

Request MDEA for your application trial

Send China Amines Co., Limited your intended co-initiator application, sample quantity and required quality parameters. Include any limits for assay, water content or color that your formulation team specifies.

For the commercial quotation, provide the expected volume, preferred packaging and destination port so we can review grade availability and documentation with your inquiry.
