    ◆Operation

    preparations

    Material preparation: Stirring in the original drum, then pouring into dispenser.

    To avoid bubbles inside of finished products, both tank should be usually kept 40 to 60 minutes under the vacuum pressure 0-2mmHg.

    Max tolerance: Mixing proportion of deviation may affect mechanical properties, tolerance should be less than 1%.

    Other: 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.

    Suggestion of molding condition

    Machine    low pressure Pouring machine 

    Mould temperature    50-60 ℃

    Material temperature  

    Part A   25-30 ℃ 

    Part B   25-30 ℃                        

    Demoulding time  10~60min 

    Manual process

    Temperature: Before using, keep the material under 25 ± 2℃ to ensure its reactivity and viscosity.

    Mixing:weigh the material at a ratio according to the above.

    Preparation:Dry all containers and mould in 70-80 ℃ oven for 1-2 hours to remove moisture.

    Process : put A and B into a container. Mixing 1-2 minutes. Degassing under 0.1 Mp negative  pressure to avoid the bubble. then potting smoothly . Should avoid the excessive speed to involving into air bubbles. 

    Cleaning: cleaning the containers by organic solvents, such as acetone and chloroform,etc.

    Comparison between the ratio and hardness

    SP2204 A : SP2204 B           hardness (DIN 53505)

    100 : 60                                70 Shore D

    100 : 55                                65 Shore D

    100 : 46                                90 Shore A

    ◆Package and Storage

    Package                           

    Each part is 200kg/pail            

    Transported as general chemical    

    Storage 

    The opened drum should be sealed

    Avoid moisture, and be used out in a short time

    Shelf life: 12months for part A; 6months for part B
