Cationic retention aid helps to binds pigments, dyes and other additives to the pulp fibres during the papermaking process.
Make a stock solution of 25g to 1 litre of water in a blender and then dilute to 5 litres. Allow to stand for several hours and use within 2-3 days. It has a refrigerated shelf life of around 9 months. Add pigment and other additives to the pulp, pigment first and then additives. Add the retention aid very slowly while stirring the pulp until the pigment is retained in the fibres. If you use too little or too much it will cause the additives to remain separate from the pulp. At this point your water should be fairly clear if not completely clear.
