Silane crosslinkers



Titanates provide functionality to a multitude of polymers – such as carbonates, sulfur, sulfur donors,sulphates, nitrides, nitrates etc.
They are suitable silane crosslinkers,providing plastics, resins and coatings(inks) with better solvent resistance,weathering, electrical and di-electric properties.
By choosing the proper titanate, this might allow formulators to design waterborne coatings with performance levels, close to solvent based coatings.Titanates crosslink cellulose or water soluble polymers to control the thixotropy of a waterborne coating.
Treated minerals and pigments can be dispersed easily in the polymer matrix, both in aqueous and nonaqueous systems while reducing system viscosity. For plastics and rubber, titanate treated minerals and fillers can increase compounding rates while reducing process  temperatures. With high use levels of certain minerals, like Al(OH)3 or Mg(OH)2 etc. titanates can improve flame retardant properties without using halogens contain compounds.Titanate treated iron oxides can make better plastic / rubber magnets.
