①All data above were tested under standardized condition.
②All data listed in the chart were for the generalized item in the series; please refer to the related data sheet for special items.
③Storage condition has a direct impact to the products’ shelf life, Please refer to the instruction for special items’ storing.
Material preparation: Stirring in the original drum, then pouring into dispenser.
To avoid bubbles inside of finished products, both tank should be usually kept 30 to 50 minutes under the vacuum pressure 0-2mmHg.
Max tolerance: Mixing proportion of deviation may affect mechanical properties, tolerance should be less than 1%.
Through the production, should always maintain the tank airtight . the compressed gas should
be dry If need, otherwise part B will become sticky, and influence the mechanical properties.
