Epoxy resin curing accelerator DMP-30 is 2,4,6 tris(dimethylaminomethyl)phenol,
which is a tertiary amine curing agent. It can be used as an epoxy resin curing
agent at room temperature, and also as an efficient accelerator for acid
anhydride, polyvinylamine and aliphatic polyamine curing agents.
This product contains phenolic hydroxyl group in its molecular structure, so
the activity is increased and it can be used for fast curing, mainly for
thermosetting epoxy resin curing agent and adhesive, and it can be used as
accelerator of acid anhydride curing agent and amide curing agent for casting
and pressure layer products, the amount of this product as curing agent is
generally about 3-13%, and the amount as accelerator is generally 0.1-3%. This
product can be used as a catalyst in rubber anti-ozone agent and rigid
polyurethane foam raw material combination polyether.

Production process.
2000L reaction kettle, 200kg of phenol, 720kg of dimethylamine, 520kg of
formaldehyde added dropwise below 50 degrees.
kg, after drop addition, raise the temperature to 70 degrees, keep warm for 2
hours, lower the temperature to 50 degrees, add 100 kg of sodium chloride
Sodium chloride, stir, let stand, stratify, and dehydrate the crude product
under pressure.

Method of preparation.
After the reaction of phenol with dimethylamine and formaldehyde, the reaction
products are stratified, dehydrated under vacuum and filtered to obtain the
finished product.

Theoretical unit consumption: (one ton of product)
Phenol: 400 kg
Dimethylamine (40% aqueous solution) 1440kg
Formaldehyde (37% aqueous solution) 1040kg
Produce waste water about 1.8 tons, mainly containing a small amount of
formaldehyde

Dosage:
As accelerator dosage is about 1~5%
As a curing agent dosage of about 10%

Application areas.
Use one
Used as curing agent for thermosetting epoxy resin, adhesive, binder for
laminate material and flooring, acid neutralizer and catalyst in polyurethane
production
Application 2
Used as antioxidant, also used in dye preparation
Application 3
Used as curing agent for thermosetting epoxy resin, adhesive, sealant for
laminate materials and flooring, acid neutralizer and catalyst in polyurethane
production.
