FennoSize AS is a performance-driven internal sizing program that consists of 100% active liquid ASA sizing products (alkenyl succinic anhydride). The synthetic sizing agents are highly reactive and together with Kemira’s efficient on-site ASA emulsification techniques, they allow over 90% immediate sizing development.
- Applied for hydrophobation of e.g. fine paper, liner, sack paper, packaging board, containerboard, and gypsum board.
- Used typically for neutral and alkaline sizing (pH 7–8), but works over a wide pH range 5–9
- No curing time needed
- Advanced production ensures high ASA sizing purity and quality
