11、Technology is suitable with any Cellulose-based substrates Oil resistance of more than 4 days at room temperature,more than 24 hours at 60 oC was fabricated Water resistance of more than 4 days at room temperature,and cobb of less than 2 MVTR of 2 digits is achievable with promising to go to lower MVTR(20 g/m2.day)Thank you
