JL-322 water swelling water-proofing gel(the JL-322) is a type of water-swelling, single-fluid and elastic sealant.
With prepolymer of polyurethane as the base, it contains urethane produced by special technology.
It has dual-sealing water –stop of concrete construction joints and antiseep of various pre-embedded components.
JL-322 may solidify at humid environment. The curing time depends on environment temperature and humidity.
The higher of the temperature and humidity , the shorter of the curing time.
Carry out next concrete grouting after the surface hardened (tacky dry).
