Application Data

Michem® Flex P1309 may applied via flexo, gravure or smooth roll coater. It can be diluted 1:1 with water or with a 50:50 pre-mixture of water and isopropyl alcohol prior to use. It has good compatibility with both Ethanol & Methanol but limited compatibility in IPA solvent. It is recommended that IPA must always be diluted with water before use. It is recommended to corona or flame-treat substrates prior to priming and dry thoroughly with hot, circulating air. This product is highly recommended for application in-line to a target coat weight on film substrates of 0.025 0.075 dry g/m2. This product was specifically designed for and is available only in Asia.
