sulfur (Magnetic 6) Chemical Profile 6/84
CHEMICAL NAME: Sulfur
TRADE NAME(S): Magnetic 6, many others (56)
FORMULATION(S): Finely ground sulfur intended for dusting is made
free-flowing by the addition of 1 to 5% clay, talc, gypsum,
tricalcium phosphate, or similar material.
Wettable sulfur is prepared by adding wetting and dispersing agents
to finely ground sulfur, since sulfur by itself cannot be suspended in
Micronized wettable sulfur is made by a special manufacturing
process to ensure an extremely fine particle size carefully balanced to
give optimum efficacy.
Colloidal sulfurs are made up of smaller particles than can be
produced by ordinary grinding processes. They may be produced in several
ways, generally by acidifying lime-sulfur solution or similar reaction.
Flowable sulfur is a microfine sulfur formulation in aqueous
suspension form. Particle size average diameter not more than 5 microns
via coulter counter measurement. It has strong adhesive properties that
will act as a sticker and deposit builder for other spray materials (56).
