1,3,5-Tris(3-dimethylaminopropyl)hexahydro-s-triazine

Product Overview

1,3,5-Tris(3-dimethylaminopropyl)hexahydro-s-triazine (CAS 15875-13-5) is a tertiary amine catalyst used in polyurethane formulations. Its main application area is rigid polyurethane (PUR) and polyisocyanurate (PIR) systems, particularly those developed for thermal insulation.

This catalyst can contribute to gelling, blowing and trimerization reactions. The balance of these reactions affects how a foam rises, sets and cures. Its performance depends on the complete formulation and processing conditions, so the catalyst package should be evaluated in the customer's own system.

Product Identification

Role in PUR and PIR Formulations

In rigid PUR foam, this tertiary amine catalyst may be selected as part of a catalyst package to help balance foam formation and curing. Gelling supports the formation of the polymer network, while blowing contributes to foam expansion.

In PIR formulations, it may be evaluated as a co-catalyst alongside other catalysts selected for trimerization. The required balance depends on the formulation and the processing method. A dosage suitable for one system should not be treated as a general recommendation for another.

Application Areas

These are formulation applications, not separate guaranteed uses for every available grade. Customers should confirm the suitability of the quoted product through their own trials.

Points to Evaluate During Formulation Trials

When assessing this catalyst, review its effect together with the polyols, isocyanates, blowing agents, surfactants and other catalysts in the system. Useful trial observations include the reaction profile, foam rise, curing behavior and finished foam properties.

For continuous panels, spray foam and appliance foam, processing conditions can differ substantially. Trial results should therefore be assessed against the requirements of the intended production process rather than a single general dosage figure.

Specifications and Documents

Before placing an order, confirm the specification of the grade offered by Aozun. Depending on your purchasing and formulation requirements, you may need to review appearance, amine value, water content, density, viscosity and other grade-specific parameters.

Request the available technical data sheet (TDS), safety data sheet (SDS) and batch certificate of analysis (COA) when discussing an order. Product specifications and batch results should be taken from those documents.

Packaging and Storage

Please confirm available packaging and net weight with your quotation. Keep containers tightly closed and follow the storage, handling and safety instructions in the SDS supplied for the offered product.

Request a Quotation

For a quotation, please provide the required quantity, destination, preferred packaging and any target specifications. If you are evaluating the product for a particular PUR or PIR system, include the application and the product documents you require so that Aozun can confirm the relevant information.

Frequently Asked Questions

Is this product used in rigid PUR or PIR foam?

Yes. This type of tertiary amine catalyst is used in rigid PUR and PIR formulations. Its suitability for a specific foam system should be confirmed through formulation trials.

What does the catalyst do in a foam formulation?

It can contribute to gelling, blowing and trimerization reactions. The relative effect of each reaction depends on the full catalyst package and other formulation components.

Can one dosage be recommended for every application?

No. Dosage should be established through trials using the intended raw materials, formulation and processing conditions.

Which documents should buyers request?

Buyers can request the available TDS, SDS and batch COA to check the offered grade, safe handling information and batch-specific results.
