Dis-901
Dispersant Dis‑901
Aqueous Dispersant for Hard and Brittle Materials
Product Overview
Dis‑901 is a block copolymer of ethylene oxide and propylene oxide. Free of APEO, it offers excellent dispersing performance for inorganic particles and can be used as an aqueous dispersant in hard and brittle material processing, including sapphire cutting and photovoltaic wafer cutting.
Product Features
- Temperature Resistance: High cloud point in aqueous solution, suitable for a wide operating temperature range.
- Lubrication & Emulsification: Good lubricity with strong emulsifying and dispersing capability.
- High Activity: Active content ≥99%, solvent-free.
- Environmental Profile: APEO-free and compatible with aqueous processing systems.
- Dispersion Performance: Excellent dispersion of inorganic particles and effective prevention of agglomeration.
