I measured the water vapor permeability using the multilayer film of Coat-X! It's perfect for moisture-proof purposes.
The multilayer coating of Coat-X is effective for waterproofing and moisture resistance. We will introduce the results of measuring the water vapor permeability. It is a higher performance coating than conventional single-layer coatings.
This article presents the results of measuring the water vapor transmission rates of the multilayer coatings CX-mC and CX-mF from Coat-X. Our company processes polymer monolayers and multilayer coatings of polymer + SiO2, and this time we compared three types: monolayer, CX-mC, and CX-mF. We hope this helps you envision which coating is suitable for your application. The water vapor transmission rate is the value indicating how many grams of water vapor (moisture) pass through one square meter in 24 hours. (Unit: g/m²/day) Polymer monolayer: 8 g/m²/day CX-mC (multilayer coating): 0.0065 g/m²/day, heat resistance: 115°C CX-mF (multilayer coating): 0.013 g/m²/day, heat resistance: 350°C CX-mC offers excellent moisture barrier properties but has a heat resistance of about 115°C. CX-mF has slightly lower moisture barrier performance compared to CX-mC but maintains a heat resistance of about 350°C. It has been confirmed that both coatings have moisture resistance approximately 100 times greater than the monolayer for CX-mF and about 1000 times greater for CX-mC. Our company proposes coatings tailored to your needs to meet your requirements.
