binder demand chem.

[Алвико]

помогите перевести, пожалуйста, следующую фразу:
pigments of low (medium, high) binder demand.

мой вариант - пигменты с низкой (средней, высокой) потребностью в связующем.

контекст:
pigments of low binder demand - pigment concentration 25 % (m/m) to 60 %(m/m)
pigments of medium binder demand - pigment concentration 10 %(m/m) to 25 %(m/m)
pigments of high binder demand - pigment concentration lower than 10 %(m/m)

и что такое (m/m)?

[Алвико]

m/m уже нашла
m/m
an abbreviation for "by mass," used in chemistry and pharmacology to describe the concentration of a substance in a mixture or solution. 2% m/m means that the mass of the substance is 2% of the total mass of the solution or mixture.
