For the result of Kemira SC 180 VS CM-P 1380, CM-P1360
as below,

1. SC 180 VS CM-P1380 performance result are similar , b
price cheaper then Kemira market price

2. We can provide the wide-products, If customer want t
SSA, you can consider our CM-P 1360, IF customer insi
compare with Kemira, you can choose our CM-P1380.

3. We believed our Surface Sizing agent will be better w
