Stronger Bonding and Hardness
Larger particle size yields higher green strengths (i.e., modulus
of rupture) and harder refractory fiber shapes.
Better High Temperature Properties
Larger particle size and lower sodium content gives lower shrinkage
at temperatures up to 2300oF.
Forms 3D gels
Can be gelled with
Wesol D30 colloidal alumina and
refractory fibers to form thick fibrous coatings.
Rigidizes Better
Larger particles soak in farther and giver stronger, harder rigidized
products.
Flocs with Cationic Starch
Negative surface charge flocs cationic starch refractory fibers
together to form a three dimensional floc for good product strength.
