Physical Properties of product

Molecular formula: C8H20N2O;

Relative molecular weight: 160.3;

CAS number: 3033-62-3;

Light yellow clear liquid;

Purity ≥99%;

Moisture ≤0.5%;

Viscosity (25℃) : 4.1mPa.s;

Density (25℃) : 0.902g/cm3;

Toyocat ET catalyst A-1 can promote chemical reactions alone or as part of an amine catalyst system and is an effective amine catalyst for polyurethane foam. It contains 70% bis (2-dimethylaminoethyl) ether, which is one of the most active catalysts currently used in industry. Niax catalyst A-1 efficiently promotes the basic chemical reaction of polyols with isocyanates and water with isocyanates, improving polyether foaming processes for high-density unfilled foams, filled foams, high-bearing soft foams, low-density foams, and high-density foams. – Elastic moulded foam.

Toyocat ET catalyst A-1 increases the specific rate constant of the chemical reaction between polyols and isocyanates by 10% compared to the next most reactive amine (A mixture of triethylenediamine). Even more impressive, Toyocat ET catalyst A-1 can achieve A specific rate constant 50% higher than that of triethylenediamine in the chemical reaction between water and isocyanate.

Toyocat ET catalyst A-1 has A powerful effect on the reaction between water and isocyanate, helping to promote a controlled acceleration of the chemical reaction between polyols and isocyanates through small changes in stanylous octoate levels – an important feature in commercial open-cell production of flexible, non-cracking polyurethane foams.

An important feature of Toyocat ET catalyst A-1 is the ability to adjust the level used over A wide range to effectively control the foam rise time – without sacrificing the range of operation of stannous capylate.

70% bis (dimethylaminoethyl) ether, a very highly active polyurethane catalyst, which is widely used in the production of all types of foam, and is especially used in more difficult to process soft foam requiring a high permeability foam structure;

Leak treatment

Stop leaks as much as possible while ensuring safety. If a minor leak is found, treat it with sand or other absorbent material and place it in a clean, dry container for subsequent treatment. If a large amount of leakage occurs, the leaked material should be collected for subsequent treatment. Avoid material entering groundwater or surface water, because it is not easily degraded by biological matter. All collected leakage materials should be disposed of in accordance with the relevant regulations of the local environmental protection department.
