Incorporate ADDSiL™ 8900 before grinding or processing to achieve the optimum effect. When post-addition is necessary, it is recommended to incorporate ADDSiL™ 8900 with sufficient mixing.
Due to its high active content, ADDSiL™ 8900 silicone additives can be prediluted to a 10% suspension with an aromatic solvent. This can allow easier incorporation. Such solutions have only limited storage stability as the hydrophobic silica will tend to settle out.
ADDSiL™ 8900 exhibits thixotropic properties. Its viscosity may increase during storage. This is normal and it is advisable to stir well before use.
ADDSiL™ 8900 silicone coating is supplied in 25Kg / 200Kg plastic drum or steel drum or according to customer's request.
In the original unopened packaging, ADDSiL™ 8900 has a shelf life of 24 months.
