- DP60 Electronic material dispersants
DP60 dispersant This product is an innovative polyester-amine block copolymer aqueous solution. It realizes the construction of a three-dimensional network structure through molecular design. It is specially developed to solve the agglomeration problem of carbon-based nanomaterials (石墨烯, 碳纳米管, 等。) and lithium-ion battery materials (silicon-carbon anode, ternary cathode, 等。) during wet grinding and spray drying. Characterized by FTIR and GPC, its molecular weight distribution D50 = 2000-5000Da, containing 30% active amino groups (calculated in KOH).
