摘要：
A hydrogel composition is formed by conveying separate first and second liquid components subject to a selectively applied application pressure P(A) into an outlet path for mixing and discharge. A liquid flushing agent is automatically conveyed into the outlet path subject to a substantially constantly applied purge pressure P(P) when the application of P(A) is interrupted, to continuously flush residual hydrogel composition from the outlet path.
