Description
Carboamidoformaldehyde pitches were widely used by production of plywood, pasting of details of furniture, joiner's and construction products, for production of wafer cores and forms, strengthening of soil, and also for production of press materials, layered

plastics, polyfoams, glues, coverings, processing of paper, fabric.

Also, KFZh is applied as glue to fixing of abrasive grains on the basis of a grinding skin. Shlifshkurka on KFZh is applied to manual and machine grinding of wood, and also to processing of other materials with average loadings without use of cooling liquid
