• D.E.R. 3415 is a bisphenol-A based epoxy resin modified with a catalyst which can be activated at temperature above 50 C
while maintaining very good pot life at ambient temperature
• It can be blended with any other epoxy resins (either aromatic and aliphatic)
• It is compatible with most of the amine curing agents (aromatic and aliphatic amines)
• It can be used to adjust the reactivity of different amine curing systems by adding different levels into the curing systems

Recent Innovation – High Temperature
4,4'-Methylenedianiline (MDA) is a suspected
carcinogen. It is included in the "substances of very
high concern" list of the European Chemicals Agency
(ECHA).
Pure methylenedianiline is a highly toxic, colorless solid.
May be fatal if swallowed, inhaled or absorbed
through skin. Causes irritation to the skin, eyes and
respiratory tract. Combustible solid or liquid when heated.
May cause methemoglobinemia. Affects blood,
cardiovascular system, central nervous system, liver and
kidneys and may cause cancer.
Ancamine DL-50 (MDA-blend)
Highly viscous / solid = light to dark brown @ 50,000 - 55,000 mPa.s (AHEW = 51 gr/eq)
DETDA
Low viscosity liquid = clear amber liquid @ 100 - 200 mPa.s (AHEW = 46 gr/eq)
Need 10% less per 100 kilo epoxy
Much lower viscosity = allows blending and use at much lowers
temperatures (room temperature)
