Melamine-formaldehyde resins

Positively charged melamine-formaldehyde colloids are developed by CHC as high efficient wet-strength resins. These aqueous resins not only promote the bonding strength among fibers, but also form three-dimensional network to protect water-sensitive chemical bonds. In the paper treated with melamine-formaldehyde resins, its dimensional stability is greatly improved during humidity changes.

Characteristics
1.Synthetic waterborne resins (easy-to-use).
2.Impart high wet and dry strength.
3.Assist in filler retention.
4.Improve paper dimensional stability.
5.Rapid curing rate.

Application
1. All paper and board grades (currency and map papers)
