Abstract [en]

The Swedish company ThermoGaia AB has sole sales rights in the Nordic region for

ThermoShield® brand, which the company markets under its own brand

Termoskydd. The paint is marketed with properties such as energy savings by heat

reflection and solves moisture problems because the paint can both be diffusion

open or closed due to climatic conditions and function like a variable vapor barrier.

These unique features come from a combination of a special binder with ceramic

beads. The unique properties of the color at varying humidity conditions are in

particular of interest to study and evaluate, which is also the purpose of the this

study.

By experimentally creating two different closed climates with differentiated relative

humidity between both sides of a material, concentration differences will occur in

the prevailing vapor concentrations provided that constant temperature prevails.

Variations in vapor levels create pressure differences that become the driving force

of the moisture transport that takes place in the form of diffusion that occurs onedimensional.

The method used in the study is a modified version of the standardized

cup method. Periodic measurements of weight differences continued until stationary

conditions were reached. The collected measurement data is then used to calculate

the water vapor migration.

The result of the study shows that the color has the ability to have a lower resistance

if the surrounding climate has low relative humidity, the greater the concentration

difference between the vapors. When the surrounding climate instead has a high

relative humidity, the color showed a higher resistance when the greatest

concentration difference occurs. The study's conclusion from the problem

formulation is that the causal relationship between the relative humidity and water

vapor migration for the color tends to change the resistance, depending on the vapor

content of ambient air, provided that stationary conditions prevail.
