Demand Market Survey For /Temperature Sensitive Paints
Importance of the Topic
Exposure to higher temperatures, than recommended, adversely affects the potency of large number of drugs, vaccines and vitamin preparations. Frozen and some of the processed food items also become unfit for human consumption, if exposed to higher temperatures. The problem is acute in India, where storage facilities at required temperature temperatures at retail outlets, especially, in remote areas, are either not available or not effective. For most of the time, due to frequent power cuts and / or failure, more so during summers, when the ambient temperature, in most parts of the country, during major part of the day is more than 300C the problem gets compounded.
In addition, there are numerous industrial applications where one needs temperature indicators reversible as well as irreversible. Reversible temperature sensitive paints and labels would find applications in the processes of repetitive nature while he irreversible ones would be suitable for endurance tests or applications where one wants to know whether a particular temperature was achieved or not at the end of the process.
The temperature sensitive paints and labels are best suited for temperature measurement, where conventional indicators can not be applied.
The applications of temperature sensitive paints (TSPs), reversible as well as irreversible, and their market potential in India in the subject of the pre cent study.
Need for Temperature Sensitive Paints / Labels
The conventional mechanical, electrical, electronics, pneumatic, hydraulic, temperature indicators do not provide a solution for measurement / monitoring of temperatures for a number of applications. Temperature sensitive paints / labels may the right candidates for such applications. Temperature indicators qualifying for the following contests may be in a position to provide a solution.
| To record the maximum temperature to which on item has been exposed during storage or transportation. | |
| To record the duration of exposure to higher temperatures. | |
| To record more than one exposure to higher temperatures. | |
| To be able to have sensor unit in / alon with each packing. | |
| Where the indicator units should occupy very little space and be not bulky. | |
| Indicator unit have to should be commensurate with the cost of the item under observation. | |
| There is a need for the Indicator unit to remain functional / effective in all the operating conditions. | |
| The indicator unit should have to be non-toxic, non-reactive to the items / contents being monitored. |
None of the available conventional temperature indicators, namely electrical, electronic, mechanical, hydraulic, pneumatic or combination of them, qualify for the above. At the outset, it appears that only temperature sensitive paints are suitable for above mentioned requirements. World over, temperature sensitive labels have been developed for complete temperature range. In India, labels are being manufactured for temperature higher than ambient and the labels for low temperature applications are yet to be developed. Though, temperature sensitive paints hold potential for a number of regular as well as strategic applications, their use and awareness has remained quite limited in India. The possible types of indicators (temperature sensitive paints / labels ) are:
| Go-No-Go Without Delay | |
| Go-No-Go with Delay | |
| Time / temperature Integrator | |
| Real-Time Recorder | |
| Multi-Temperature : Go/No-Go | |
| Multi-Temperature with Time Element. |
Availability of Tempearture Senstitve Paints/ Lables
A detailed scrutiny of appropriate publication, visits to relevant institutions and discussions held with concerned officials / research workers revealed, that till date, no development work has been carried out in India on irreversible temperature sensitive paints or labels required for pharmaceutical industry. The institution presently engaged in imparting education and carrying research on paint technology are :
Department of Chemical Technology, University of Bombay, Matunga, Bombay.
| Department of Chemistry, Pune Universiy, Pune. | |
| Harcourt Butler Institute of Technology, Kanpur. | |
| Department of Chemical Engineering, IIT, Delhi | |
| Department of Chemical Engineering, IIT, Bombay | |
| Laxmi Narayan Institute of Technology, Nagpur |
