Branched Aliphatic diamine. Used in adhesives. Acts as a hardner.
تفاصيل
Trimethyl hexamethylene diamine
with approximately equal parts of the 2,2,4- and 2,4,4-trimethyl hexamethylene diamine isomers
- low viscosity
- long pot life
- products cured with Vestamin® TMD are clear and non-yellowing with good flexibility and chemical resistance
Adhesives
as a hardner for epoxy resin systems and the synthesis of polyurethanes and polyamides
the starting point for synthesis in the field of anti-corrosives, emulsifiers, vulcanization accelerators, pesticides, textile auxiliaries, flotation media, lubrication oil additives
casting resins for electrical use
solvent free and solvent containing lacquers and coatings
Vestamin® TMD is slightly hygroscopic and tend to form carbamates by reaction with atmospheric CO2. it should be stored free from moisture and carbon dioxide in glass, stainless steel and similar containers.
Vestamin® TMD is stable for at least one year when stored in original containers at temperatures below 25 °C .
