V-3 (Diak® No.3)
V-3 is diamines cross-linking agent used in Fluoroelastomer(FKM) as well as Polyacrylic ( ACM)
elastomers .
Compounding and Processing
V-3 used as an acid acceptor system is low activity magnesium oxide. Calcium oxide may be used in
place of magnesium oxide to reduce the shrinkage of compounds of FKM during cure, eliminate air entrapment in thick sections, and improve compression set resistance.
Compounds of FKM cured with V-3 should be mixed on mill that is kept as cool as possible. The FKM
curing agent should be blended thoroughly with the filler before either it or the filler is added to the polymer.
Handling Precautions
- V-3 may form flammable dust –air mixtures.
- They may cause irritation of eyes and skin. Keep away from heat, sparks, and open flame. Use
only in areas Provided with grounded equipment. - Breathing of dust and contact with eyes, skin, and clothing should be avoided.
