Process condition

1.Ratio for reference

    Dilute the product with ethyl acetate or dimethylbenzene.(viscosity:130s-150s(4# cup))
    Ratio of main agent and curing agent:10:2-3
    Add curing agent into mixed liquid cement, and stir the mixture uniformly.
2 .Temperature of Drying Tunnel:first stage:50℃ ~60℃;second stage: raise the temperature by degree until 120℃ above.
3.flow velocity of coating material in drying tunnel is subject to the curing degree of adhesive.
4.If curing agent isn't added, composite should be baked at 120℃-160℃ for 10-20 minutes in baking oven.
