High-surface-area carbon blacks and fumed silica are more efficient on an equal-weight basis as reinforcing agent than other rheology-control additives. Carbon black is used to build viscosity, provide sag resistance, and increase the cohesive strength of automotive windshield adhesives. Coated precipitated calcium carbonates (PCCs) are used for rheology control of STP and polyurethane adhesives and sealants. Those PCCs with hydrophobic coatings (e.g., fatty acid or stearic acid) do yield shear-
Molybdenum disulfide production methods include natural, direct synthesis, ammonium tetrathiomolybdate thermal decomposition, and hydrogen sulfide or sulfur steam reduction methods. Among them, the natural method that molybdenite concentrate purification method, molybdenum concentrate after a certain physical and chemical action, remove impurities such as silicon trioxide, iron, copper, calcium, and lead, and then further refines the process of MoS2. Direct synthesis is when molybdenum and sulfu
