surface sizing agent 25% anionic styrene acrylic

Product Description Anionic surface sizing agent is a new type od surface sizing agent that synthesized by the copolymerization of styrene and ester.It can efficiently combinate with starch result good cross link intensity and hydrophobic properties.With lower dosage,low cost and easy use advantages,it has good film-forming property which can significantly improve the water-resistance and ring-crush strength of writing and printing paper,such as offset printing paper and electro-photographic paper. Our quality can compete with BASF400DS and BASF8903. Specification&Index

Application It can be applied in combination with anionic and nonionic auxiliaries such as starch,direct dyes,acid dyes and fluorescent whitening agents,etc. The paper does not necessarily have to be sized at the wet end and before it is applied,but this can be an effective means of controlling the extent to which the size is able to penetrate. It can significantly improve the water-resistance and ring-crush strength of offset printing paper and electro-phototgraphic paper. It also has good mechanical stability with less bubbles generated during the operational process. Application temperature should be below 75℃. Packing & Delivery 200kg PE drum or 1000kg IBC drum.
