x% active calculated as

@ Marga Actually, this is the whole sentence. Here's more:
"XXX is a multifunctional pigment that is used in coatings as corrosion inhibitor, ultraviolet light stabilizer, tannin stain blocking agent, flame retardant, and white rust inhibitor (zinc rich paints). Because it is multifunctional it can replace five or six products commonly warehoused by paint companies. The use of XXX results in less product storage, a faster turnover of raw materials, and a savings in raw material costs.
XXX is the commercial form of modified barium metaborate monohydrate. It is + 90% active calculated as BaB2O4.H2O. Because it has a low refractive index (1.55-1.60) it can be used in a wide variety of colors and whites. It may even be usable in some clears and varnishes."

Es ist ein Pigment. Google findet dies hier:
"Busan® 11-M1 is the commercial form of modified barium metaborate monohydrate. It is 90+% active calculated as BaB2O4 H2O."

Man könnte den Anfang als "Mehr als 90 %" lesen, aber auf welche Eigenschaft sich das bezieht, weiß ich nicht; jedenfalls nicht auf die Photoaktivität, die soll ja möglichst klein sein.

@ LegalTrans D Please could you provide more context, at least a whole sentence. This would help.
