Coating can indicate contamination

Monday, 8 February 2010

Chemists look for self-decontaminating coatings based on chemical adsorbtion and reactive agents containing catalysts.

A strippable paint coating that can decontaminate itself after absorbing chemical agents is the aim for scientists at the Defence Science Technology Laboratory (Dstl). Currently, strippable coatings are used on military vehicles in theatre to change the colour of vehicles quickly. The application of these coatings requires minimal training and can easily be applied and removed by soldiers. 90 % of the coatings can be removed by scoring flat areas with a knife and then manually peeling it off, complex areas can be scored and then removed with high-pressure water. The coatings also have a use in temporary camouflage as the paint can be used to flexibly adapt a vehicle’s colour and glint signature, reducing the vehicle’s visibility. The current generation of coatings have at least a 12 month life span on the vehicles. Researchers evaluate the coatings for use in decontamination to become the next coatings generation which will be able to absorb chemical biological and radiological agents (CBR), therefore protecting those operating inside and around the vehicle. Furthermore the chemists look at reactive coatings which would contain catalysts and possibly enzymes in order to create self-decontaminating coatings.
