The crosslinking reaction usually takes put at elevated temperatures. Successful crosslinking temperature vary with the type of amino resin read more from a hundred twenty five to 200°C, and also the reaction is often acid catalyzed. The crosslinking temperature might be decreased by utilizing enough amount of solid acids like hydrochloric acid & organic acid like p-toluene sulphonic acid. Utilizing natural and organic acid curing, temperature can be decreased as good as 80 to 130°C. This system can be employed where by heat sensitive substrates like plastic pieces are to become coated. Amino resins useful for crosslinking are urea resins, melamine resins & benzoguanamine resins.
