Title: Karikath Su Varma: Innovator in Fire Resistant Glazings

Introduction

Karikath Su Varma is a notable inventor based in Southport, GB. She has made significant contributions to the field of fire resistant glazings, holding 2 patents that showcase her innovative approach to enhancing safety and performance in glazing materials.

Latest Patents

Her latest patents include a method for the production of fire resistant glazings that feature improved properties. This method involves a silicate-based interlayer containing 35% to 43% by weight of water, produced using a cast-in-place process. The water content in the interlayer can be reduced by concentrating the silicate solution or by introducing silica in the form of a silica sol. Additionally, a mixture of an aqueous sol and an organosol is preferred. To further enhance the properties and reduce water content, polyhydroxy compounds and saccharides may be incorporated into the interlayer. The resulting silicate-based formulations are pourable and can be cured to form an optically clear interlayer. Another patent focuses on the incorporation of polyvalent metal ions, such as aluminium and zirconium ions, into a silicate-based interlayer in laminated fire resistant glazing, which improves the properties of these glazings.
