PRODUCT POSITIONING
M-2377 is a rutile titanium dioxide pigment with zirconia and alumina inorganic coating and organic treatment. Its approved Application directions cover coatings, plastics, masterbatch, printing inks and paper. Sulfate is the approved process classification. Use M-2377 as a candidate when gloss, durability, dispersion and optical properties are relevant to the intended system. Final selection should account for formulation, resin or binder, pigment loading, additives, dispersion process, processing or application conditions, finished appearance and destination documents.
APPLICATION DIRECTIONS
Review each approved direction in the intended formulation, processing, application and end-use conditions.
Evaluate M-2377 in the intended coating formulation and process. The technical source lists interior and exterior coatings, emulsion paints, powder coatings and primer paints. Confirm gloss, dispersion, durability requirements and finished-film performance in the buyer's system.
Evaluate M-2377 in the intended polymer, additive package, pigment loading and processing conditions. Confirm dispersion, optical performance, appearance and end-use requirements.
Test M-2377 in the selected carrier resin, pigment concentration, additives and compounding process. Confirm dispersion, let-down behavior, color and finished-part performance.
Evaluate M-2377 in the intended ink vehicle, pigment loading, dispersion process, print method and substrate. Confirm dispersion, optical response and printed appearance.
Review M-2377 in the intended paper formulation or coating context. Confirm dispersion, whiteness and finished-sheet requirements under the buyer's process.
FORMULATION EVALUATION
Use the documented M-2377 profile and typical data to frame buyer testing.
These evaluation priorities identify what to check during buyer testing. They do not guarantee fixed results.
