Context
Cameras mounted in sealed enclosures on autonomous mobile machines, in permanent outdoor duty. Condensation was forming on the optics and degrading image capture.
Test
Comparative test run by the manufacturer: one camera fitted with a 10 cm² AS-B sticker, one identical control camera with nothing. Fogging induced by chilling.
Result
Fogging appeared on the control camera, none on the equipped camera.
Where the customer stands
The manufacturer decided to fit its fleet in series. Oven-cycling tests are planned in addition, without affecting that decision.

Context
A 0.6 L IP67 camera enclosure installed outdoors, with no possibility of on-site intervention. Winter condensation on the optics made the system unusable.
Test
Climate chamber, 48 h at −1 to +3 °C and 90–94 % RH, with one AS-B strip inside, sized to the rule of roughly 10 cm² per litre. The test was run by the customer and recorded in their own technical investigation report.
Result
Inner glass and optics completely dry across the full 48 hours.
Where the customer stands
The customer was evaluating heated glass in parallel. They chose the passive solution, at 0 W, and placed an order.
Diagram of the test set-up. Schematic representation, not to scale.
Context
Camera and electronics enclosures on autonomous agricultural machines, IP65+, in two formats. Silica gel and pressure compensators were already fitted and were not sufficient: even the small enclosures were affected.
Test
Evaluation run by the customer’s engineering team, on enclosures pre-loaded with moisture, with the pressure compensator left in place.
Result
The sticker draws the moisture out of the enclosure despite the compensator being present. Internal report validated and escalated to management.
Where the customer stands
The internal report was validated and escalated to management, then confirmed by a technical review at CTO level. The project has moved into industrialisation.
Diagram of the test set-up. Schematic representation, not to scale.
Context
IP54 instruments for which internal condensation must be controlled over a service life of more than ten years.
Test
The manufacturer ran its own thermal cycling of enclosures, with and without the AS-B sticker, under controlled humidity — entirely independently, on material bought from our online shop.
Result
Preliminary data judged promising by the manufacturer, who confirms the sticker’s potential in their configuration.
Where the customer stands
On the strength of its own measurements, the manufacturer has started listing the product with its purchasing and supply chain teams, with series production in view.
Diagram of the test set-up. Schematic representation, not to scale.
Context
Large sealed volumes housing critical electronics, with the humidity tolerance raised to 80 % RH and fire and smoke qualification required on any added material, to aerospace standards.
Test
Three campaigns. (a) 300 cm² of active material in a closed box against an unequipped control box. (b) Vertical 12 s flammability, and smoke density and toxicity, at an independent laboratory. (c) A real 60 L container, 0.1 m² of material sized with our simulator, 10 days at 38 °C and 95 % RH, benchmarked against desiccant sachets with an aluminium witness box.
Result
No condensation on the equipped side, while the control box goes above 100 % RH. Performance validated at both 160 cm² and 300 cm². Smoke density and toxicity: pass. Flammability: pass once the material is bonded to an aluminium plate, whatever the binder.
Where the customer stands
Humidity-control performance is settled. The remaining tests address other criteria — fire behaviour on the new formulations, adhesive ageing, tests on target objects — not anti-condensation efficiency.

Context
Sealed connected water-analysis sensors, manufactured in volume, with humidity-sensitive electronics inside a closed housing.
Test
Evaluation carried out in our laboratory on the customer’s actual housings, with the report handed to their product team.
Result
Results in line with the customer’s expectations, on their own enclosure geometry.
Where the customer stands
Moved to series integration on the production line, in pre-cut reel format. First production runs delivered, with volume ramp-up committed for the following year.
Diagram of the test set-up. Schematic representation, not to scale.
Context
IP65 charging stations of 95 litres, installed outdoors and connected. The daily temperature swing inside reaches 14 °C: the enclosure breathes, humid air enters through the seals and cable glands, and moisture accumulates.
Test
An 85-day field study in mid-winter, from 25 January to 20 April, on three identical stations from the same fleet: two controls and one fitted with two AS-C strips (0.32 m² of active material). Four temperature and humidity loggers at a 5-minute interval, including an outdoor reference, giving 24,385 aligned measurements.
Result
Time spent above 95 % RH — the band where condensation forms on cold walls and components — drops from 13.3 % to 5.1 %, a factor of 2.6. Internal humidity variability is divided by 3 and correlation with outdoor humidity falls to 0.02: the atmosphere inside the station is decoupled from the weather. No power, no maintenance.
Where the customer stands
The measurements make it possible to derive the water flux entering through the sealing defects, about 200 mg per day, and therefore to size by calculation rather than by rule of thumb.

Context
Self-storage units and storage containers, unheated and unventilated, where condensation damages the goods inside and generates customer complaints. Salt absorbers and desiccant sachets are consumables that have to be replaced continuously.
Test
Pilot phases on sites in real operation, at several French operators: AS-C strips installed on the ceiling of the units, then monitored over a full season with the operations teams.
Result
The pilots proved out site after site, and converted into repeat orders — the most reliable signal in this business, since an operator only reorders once their customers stop complaining.
Where the customer stands
The solution is in routine operation at French operators, across dozens of equipped sites, with regular repeat orders. It is the oldest and widest deployment of the AS-C range.
Diagram of the test set-up. Schematic representation, not to scale.
Context
Thermally uninsulated shipping containers, where the day/night swing produces "container rain": relative humidity climbs sharply at night and water drips from the ceiling onto the goods.
Test
Two identical 10-foot containers instrumented for temperature and humidity. Three days empty first, to verify that both behave identically with no outside influence. Then a sized strip installed in one of the two, with readings continued over several months.
Result
The equipped container stays below 80 % RH, under the condensation threshold, while the control follows the day/night cycle undamped. The strip’s spontaneous regeneration is visible on the curves every day.
Where the customer stands
The strip stayed in place for close to a year with no loss of performance — the longest continuous observation we have of the material regenerating.
Read the full field study →In most of these enclosures, something was already fitted: a pressure-compensation vent, a desiccant sachet, sometimes a heater. Those three solve different problems.
It equalises pressure and blocks liquid water. It does not remove the vapour already inside the enclosure, and it lets humid air back in on every breathing cycle.
Silica gel and molecular sieves adsorb from very low humidity, then saturate. Once saturated they do nothing, and they cannot regenerate in service — hence a replacement interval.
It works, but it draws power continuously. On a mobile machine or a remote site, that energy is not always available — nor free.
SRD is a mesoporous alumina, chemically inert. Most of its capacity sits in the 60–100 % RH band, which is where condensation actually forms, and it desorbs on its own as humidity falls. Every day and night cycle regenerates it. No power, no maintenance, nothing to replace over the life of the equipment.
That is why several of the cases above moved into multi-cycle or multi-year qualification rather than a single-shot test.
On request
Alongside the cases above, further evaluations are running at industrial customers. They have no consolidated result yet, so we publish neither conclusions nor company names. Here are the sectors covered.
16 evaluations — Status as of 24 September 2026
If your application resembles one of these families, we will send you the anonymised detail of the relevant evaluations: enclosure type, volume, exposure conditions, test protocol and current stage. No company names, and no result presented as established while it is not.
Sizing is one rule: about 10 cm² of active material per litre of internal volume, meaning one 50 × 20 mm sticker per litre, oversized for severe climates. Nothing else to calculate beyond the internal volume of the enclosure.
No minimum quantity, no purchase order to raise. That is exactly how case 4 started.
