Abstract
A method of coating a substrate with a white molecular coating. A colloidal based primer is prepared having on a mass basis between 30-40% suspensions of fine-sized spherical particles of nonporous silica dispersed in liquid phase. The primer is applied to the substrate and allowed to dry. A molecular adsorber coating is prepared by treating a zeolite with a colloidal silica binder thereby providing a treated pigment having a mass ratio of the colloidal silica to the zeolite is in a range of 2.0 to 2.6, then processing the treated pigment into a powder thereby facilitating sprayability and then mixing said treated zeolite with a colloidal solution containing silica. The coating is then sprayed onto the primer and allowed to dry. The resultant coating provides adequate bond stability and strength necessary for flight applications within an environment for vacuum of space applications.
