DIN, ISO or ASTM methods roughly describe our analytical procedures. But the actual method used internally is more precise and we can provide it on request. Modified with 30% salicylic acid in methanol and cooled.

Properties
VESTAMIN TMD is a low viscosity liquid, at ambient temperature It can be mixed with water in any proportion. It is a strong base with a pH of 11.6 in a 0.1 N solution. VESTAMIN TMD is soluble in many polar organic solvents including esters and alcohols. VESTAMIN TMD will undergo typical chemical reactions of fatty amines, that is, react with phosgene, aldehydes, epoxy resins, organic acids, ketones, etc. There was no significant difference in the reactivity of the isomers.

Applications
VESTAMIN TMD exhibits properties similar to hexamethylenediamine, but Its unique properties allow it to be used in many special applications. Typical areas of application include the production of hardeners for epoxy resin systems and the synthesis of polyamides and polyurethanes. It is also needed at the beginning of the synthesis of anti-corrosion agents, emulsifiers, vulcanization accelerators, biocides, printing and dyeing auxiliaries, flotation media, lubricating oil additives, etc.

Epoxy curing agent
Compared with other short-chain aliphatic diamines, VESTAMIN TMD The pot life is longer, and will not prolong the final curing time. Products cured with VESTAMIN TMD have a transparent appearance, no yellowing, good flexibility and chemical resistance. It can be used with all types of epoxy resins such as electrical resins, solvent-free and solvent-borne varnish coatings.

Shipping and Packaging
VESTAMIN TMD comes in 20 kg non-returnable cans, 180 kg Non-returnable drum or bulk. According to the existing exception license situation stipulated in Appendix C/GGVE and GGVS, we can also use rail tank car and road tank car to provide this product to European users, but such transportation should comply with the relevant regulations of Appendix I/RID (CIM) or ADR special bilateral agreements.
For North American customers: VESTAMIN TMD products are available in 44 lbs Returnable cans and 397 lb non-returnable drums.

Storage
VESTAMIN TMD is slightly hygroscopic and easy to mix with atmospheric Carbon dioxide reacts to produce carbamate. Storage should be in glass, stainless steel and similar containers to keep away moisture and carbon dioxide. Under normal conditions only carbon steel materials are sufficient, but aluminum should be avoided. VESTAMIN TMD is stable for at least one year if stored in the original container below 25ºC.

Safety and Handling
