Additional Notes
<1>. The standard specifications listed above are suitable for hand lay-up, filament winding, and pultrusion. Other variants, such as the anti-sag type SWANCOR 901-T or the accelerator-containing type SWANCOR 901-P, are also available in various specifications and can be supplied in large quantities upon customer request.
<2>. SWANCOR 901 is a reactive resin and should be stored in a cool place. If stored for an extended period, open the drum lid to allow air to enter and extend its shelf life.
<3>. The gelation characteristics of SWANCOR 901 are affected by climate, temperature, hardener content, accelerator content, and additives. Before altering the formulation, it is advisable to test the gelation time with a small batch to ensure proper processing.
