Carbamide-formaldehyde concentrate (CFC) TY 2181-032-00203803-2003

CFC is used as a semi-product for the production of urea formaldehyde, melamine-carbamide-formaldehyde resins and for carbamide treatment to resist slumping; it is used in woodworking and furniture industry for production of plywood, chipboards, etc.


Production: The CFC production method bases on catalytic oxidation of methanol to formaldehyde along with subsequent absorption of formaldehyde with carbamide solution.

Basic physical and chemical features:


Homogenous viscous liquid

Mass share of total formaldehyde, %

58,0 ± 2,0

Mass share of carbamide, %

23,0 ± 2,0

Mass share of methanol, %, not exceeding


Concentration of hydrogen ions, pH

7,0 - 9,0

Buffer capacity, ml, not exceeding


Mass share of dry residue during calcinations (ash content), %, not exceeding


Mass share of methylol groups, %, at least


Funnel viscosity at temperature (20±05) °С, by flow meter VZ-246 (nozzle 4 mm), s, not exceeding


Terms and periods of storage:

Storage temperature, °С

(+10 +30)

Warranty storage period (since the date of fabrication)

6 months

At low temperatures (down to -40, °С) CFC turns into paste (it gets sluggish). When it is heated in accordance with the requirements of specifications, it returns to the initial state. 


It is supplied in rail cars (model 15-1487-01).

Consumers of these products get considerable benefits.

The use of CFC in the technology of carbamide-formaldehyde resins makes it possible to:

  • Withdraw the product concentration stage from the technological process and reduce production expenditures;
  • Resolve the problem of disposal of formaldehyde containing waste waters, methanol and formaldehyde containing gas discharges;
  • Reduce expenditures for transportation by 40%, as CFC will be required by 1.6-2.2 times lass then formalin;
  • Reduce required carbamide by 25%;
  • Provide synthesis of low-toxic highly water-resistant resins with the spatial structure of polymers;
  • Ensure high quality of obtained carbamide-formaldehyde resins (with methanol content by 0.2%), fabricate particle boards of E1 emission class;
  • Reduce methanol discharges by several times in the process of pressing.
