Dimethylcyclohexylamine (DMCHA)
Addocat 726 B is a standard balanced catalyst for rigid foam, applicable to PIR formulations.
Addocat 726 B is dimethylcyclohexylamine.
Addocat 726 B acts as a catalyst for the production of rigid polyurethane foam.
Addocat 726 B is suitable for use in insulation of refrigerators and foam filling of intricately shaped cavities, continuous and discontinuous production of building board (foam thick-ness <80 mm; also with rigid or metal facings) and of insulating panels with flexible facings (foam thickness 15-100 mm), production of insulations by the layer-by-layer method.
Dosage: 1-3 p.b.w., calculated on 100 p.b.w. polyol.
Addocat 726 B has a shelf life of 12 months.
Addocat 726b is a polyurethane catalyst based on a tertiary amine, specifically dimethylcyclohexylamine.

Product information about Addocat 726 B:
Addocat 726 b catalyses the gas and crosslinking reaction of rigid polyurethane systems.
Dosage:
1-3 p.b.w., calculated on 100 p.b.w. polyol. In the foam filling of intricately shaped cavities Addocat PV or Addocat 108 is used at 0.1 - 0.3 p.b.w. as a co-catalyst in combination with Addocat 726 b.
Addocat 102 (at 0.5 - 1.5 p.b.w.) has proved particularly suitable as a co-catalyst in the production of sandwich panels.
Application of Addocat 726 B:
Insulation of refrigerators and foam filling of intricately shaped cavities.
Continuous and discontinuous production of building board (foam thickness < 80 mm; also with rigid or metal facings) and of insulating panels with flexible facings (foam thickness 15-100 mm).
Production of insulations by the layer-by-layer method.
Packing of Addocat 726 B:
metal drums, contents 160 kg
IBC, contents 800 kg
Storage stability of Addocat 726 B:
Addocat 726 b is hygroscopic and must therefore be protected from atmospheric humidity.
Addocat 726 B turns yellow on exposure to air and light, but without losing its catalytic effect.
Addocat 726 b should be stored at temperatures of about 20 °C.
Prolonged exposure to temperatures above 30 °C may cause discoloration, even in closed containers.
The storage life of Addocat 726 B in firmly closed original containers is 12 months.
Handling of Addocat 726 B:
Consult material safety data sheet (MSDS) for additional handling information for Addocat 726 b.
