Colloidal Silica By Prabhat Silicon Pvt. Ltd.

We are instrumental in exporting, manufacturing and supplying of Colloidal Silica in Mahesana , Gujarat , India. Colloidal Silica systems are very stable; able to form a long life ceramic slurry with a large range of refractory materials due to the binder's chemical inertness. This versatility allows Colloidal Silica to form the basis of ceramic shells used for the casting of a large range of metal alloys. Ceramic shells formed with colloidal silica binder's offer several advantages for the investment process. The exceptionally strong bonds formed by the colloid enables ceramic shells to have a superior green and fired strength. Benefiting the investment caster with: An increased maximum pour weight Reduced material usage in the back up coat Better handling Furthermore, use of colloidal silica binders has allowed investment casters a greater freedom of design with an increased level of intricacy to castings. Ceramic shells using colloidal silica binders also display excellent refractory properties, high thermal resistant, with good resistance to thermal shock and crucially.
