 Water swelling sealing glue 
 Water swelling sealing rubber expansion rate PJ220 and PJ400 features of a case of wet hardening single-liquid type, excellent construction. Two. 
 Water swelling sealing effect can be more reliably play. Concrete, metal, glass paste is very good. 
 Swellable super-sealing plastic sealing material PJ220 and PJ400 as construction excellent sealing material, is the expansion of the water of the critically acclaimed single-liquid type sealant. A hardened into a good recovery rubber elastomer, after immersion in water volume expansion, filling the gap to play the exact sealing effect. As civil engineering, construction engineering waterways peripheral sealing material can play a good performance, use very wide. 
 PJ220 and PJ400 features composite GB: JG/T312-2011 
 Expansion for the determination of water swellable super-sealing plastic sealing material PJ220 and PJ400 water conditions ● after hardening (7 days) soaking in water, determination of its rate of increase of volume. 
 ● the size of the test piece: 40X2X40mm ● Water temperature: 20 ± 5 ° C expansion rate due to the shape of the coating cross-section varies.
