NYACOL® offers colloidal alumina in the form of water based sols, EG sols, and spray dried powders. The alumina is in the form of pseudo-boehmite or boehmite powder with high purity and high surface area. Please refer to the product data sheets for individual product details.
NYACOL® AL-A4 is a well crystallized alpha alumina supplied at alkaline pH and solids of 15-20%. It is designed for polishing of metals, glass, sapphire and plastics, or as a filler for abrasion resistant coatings.
NYACOL® AL10.7 is a new, negatively charged colloidal alumina sol. AL10.7 applications include colloidal alumina rigidizer, catalyst wash-coats and formulated catalysts, paper coatings for ink receptive coatings and for lithium ion battery separator and cathode coatings.
Non-halogen flame retardant additive and flame retardant synergist with high surface area.
A negatively charged alkaline alumina sol for catalyst support.
NYACOL® AL-A4 is designed for polishing of metals, glass, sapphire and plastics, or as a filler for abrasion resistant coatings. The product has a dispersed size of 250 nm.
For use as a binder for high-temperature refractories and ceramics.
NYACOL® AL20-EG is a colloidal dispersion of high purity pseudo-boehmite alumina dispersed in ethylene glycol. It has been designed to be used in PET synthesis or as a coating additive. The solid phase refractive index of the Al2O3 particles is 1.65, which is very close to PET at 1.63. AL20-EG is expected to be a highly transparent antiblocking additive in PET film.
For use as a binder for high-temperature refractories and ceramics.
High-temperature coating/binder. Used in applications where a water-based system cannot be used.
Applications include catalysts, as a binder for ceramics and refractories and paper coatings.
