Using calcium thin film substrates, evaluate the barrier performance of flexible substrates and adhesives, as well as the outgassing of dam and fill materials.
Our company manufactures and sells calcium (Ca) thin film substrates that can evaluate barrier (sealing) performance. These Ca thin film substrates are suitable as substrates for evaluating water vapor transmission rate (WVTR, calcium corrosion method) as specified by JIS and other standards. WVTR can be calculated by determining the area of the oxidatively degraded (translucent) region of the Ca thin film with precisely defined thickness, estimating the amount of oxygen and moisture that reacted with calcium from the remaining film thickness and Ca density. This value allows for accurate comparative (quantitative) evaluation between samples. The thickness of the Ca film on the substrate is strictly managed by regularly checking the deposition and film formation conditions. Additionally, during Ca film thickness measurement, aluminum with good coverage and reproducibility is deposited on the thin film to prevent swelling of the Ca film, allowing for accurate thickness measurement and calculation of deposition conditions. 【Features】 ■ Highly reactive to moisture and oxygen, with good sensitivity ■ Much more cost-effective than using devices like organic EL as sensors ■ Changes before and after oxidation (from metallic luster to translucency) are visually easy to understand ■ Safer than other metals and easy to handle after use *For more details, please download the PDF or feel free to contact us.
