Melamine Formaldehyde Resin

MELRES – W

MELRES – W, a liquid Melamine Formaldehyde Resin improves the wet strength of paper as well as retains the desired absorbency when added in optimum proportions. It is suitable for most of the grades of paper pulp used in paper/tissue and board manufacturing.

In addition, it imparts resistance to wet rub, the wet tear and the folding endurance when wet. The dry strength is also improved to some extent. Melamine Formaldehyde is resistant to hydrolysis and therefore is preferred if the paper is required to retain its wet strength for long periods, particularly under excessive humid conditions.

It has no affinity for cellulose in the form supplied and required conversion to a cationic acid colloid solution before use.

SPECIFICATION

: Appearance : White Viscous Liquid
    Solid Content  : 56% ± 1%
    PH : 8.5 ± 0.5
    Water Tolerance : 1 : 4.5 ± 0.5
         

APPLICATION

: Resin : 10 Kgs.
    Water : 100 Ltrs.
    Conc. Hydrochloric Acid : 2.8 Ltrs.
         

MIXING  PROCEDURE

: Initially the 10 Kgs. Resin is to be taken in 50 Ltrs. Water. Acid is then added and stirred. Additional quantity of  50 Ltrs. of water is then added and stirred. The solution is then left for ageing before use. This procedure leads to the development in the solution of a blue opalescence characteristic of colloid formation. This “acid colloid” has the necessary cationic properties and is then suitable for addition to the stock in suitable proportions to impart desired wet strength and absorbency.
     

STANDARD PACKING

: 50 Kgs. and 100 Kgs. High Density polythene Carboys.
     

STORAGE LIFE

: 4 weeks, subject to airtight storage in a cool dry Place.
