Cross-contamination can result in cured
material in fluid lines which could cause
serious injury or damage equipment. To
prevent cross-contamination:
• Never interchange component A and
component B wetted parts.
• Never use solvent on one side if it has
been contaminated from the other side.
Always provide two grounded waste
containers to keep component A and
component B fluids separate.
