Melamine primarily provides a base material for resins, for example melamine-formaldehyde (MF) and melamine-urea-formaldehyde (MUF) resins, which belong to the group of aminoplastic resins. The most common use of melamine-based resins is as a wood adhesive. Melamine-formaldehyde (MF) resins of improved environmental compatibility were synthesized at different molar ratios, temperature and pH. This is because the cost of MUF resins depends on the ratio of melamine and urea. Note. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.)
