A 600ml piece of Hengshui Ruida rubber is preferred as a high-quality polyurethane water swelling sealant

  Super water stop materials pj220 and pj400, as water stop materials with excellent constructability, are water expansion single liquid sealant
Once hardened, it will become a rubber elastomer with good recovery
After immersion, it will expand its volume and fill the gap, so as to give play to the real water stop effect
As a water stop material around waterways in civil and construction engineering, it can give play to excellent performance and a wide range of applications
Chinese Name: water swelling water stop adhesive special , Excellent constructability and good water stop effect , The expansion rate of black paste expansion ratio pj220 (yx220) and pj400 (yx440) varies with the shape of the coating section , It is used for concrete, plastic secondary products and other physical properties
Water expansion paste sealant catalog 1 Introduction 2 characteristics 3 water expansibility 4 purpose introduction editing
Water expansion water stop adhesive is divided into pj220 and pj400 according to expansion ratio
Feature editing 1 Because it is a wet hardening single liquid type, it has excellent workability
2
Expansion in case of water can give more definite play to the water stop effect
3
Good adhesion to concrete, metal, glass, etc
