Disinfectant Glass

SynThera has recently developed and patented a unique set of bioactive glass materials and formulations that achieve disinfection of a variety of surfaces over timespans as long as 48 hours post application. SynThera’s disinfectant formulations comprise: (1) bioactive glass powder as the active ingredient for long-term disinfection and (2) a liquid disinfectant medium for instantaneous disinfection. In this system, the bioactive glass achieves long-term disinfection by release of ions of calcium, phosphorus, sodium, and metal ions of our choice over an extended period of time. The release of such ions leads to significant pH changes in the surrounding environment, thereby inhibiting microbial growth. Interaction of these ions with microorganisms causes disruption of cell wall permeability, resulting in nutrient uptake failure. Also, metal ions bond to various parts of the cell, such as the DNA and RNA, cellular proteins and respiratory enzymes, causing all life support systems in the cell to be immobilized. As a result, cellular growth and cell division are impacted, causing the microbes to no longer multiply and eventually die out. The ion release also leads to an increase in osmotic pressure which creates an environment not suitable for microbes. The metal ions are known to possess antiviral effects by disrupting the viral coating and destroying its RNA. The product is non-toxic and noncorrosive in nature. This is a recently patented technology in India. We are open to partnerships with companies to further develop the technology and bring it to the global markets. Please reach out to us if you would like to find out more about this pioneering technology and how it can be incorporated in your products!

Sealing Glass

Offering tunable thermal expansion properties, stability under thermal cycling, and resistance to chemical attack, sealing glasses are used to produce reliable hermetic seals between glass, metal, and ceramic components. Sealing glasses are special types of glass used to seal or bond various electrical and electronic components. For many decades, they have been used widely in the electronics industry to create structural, hermetic, and highly insulating electrical seals between different materials such as metal, glass, or ceramics. More recently the use of sealing glasses has expanded to a broader range of applications. But different devices and usages have different demands, making it crucial to select the sealing glass with optimum compatibility. The most critical characteristic of a sealing glass is the coefficient of thermal expansion (CTE), which should be as close as possible to the substrate material being sealed – typically called a “matched” fit – to prevent stress within the glass and/or substrate that can lead to cracking and failure. In some special configurations, a “compression fit” can be employed, allowing the joining of two significantly different thermal expansion materials by an intermediate glass. We at SynThera can offer sealing glasses of standard as well as customized compositions depending on the customer’s requirement. We are particularly enthusiastic to work with our customers on sealing glass materials that are suitable for their complex requirements.
