Waterproof one-component polyurethane sealant for embedded components in underground railway construction joints is water-proof. Water-proof one-component polyurethane sealant for embedded components in underground railway construction joints is water-proof. One-component polyurethane sealant for embedded components in underground railway construction joints is water-proof. Water-swellable sealant is water-tight for embedded components in underground railway construction joints. One-component polyurethane sealant that is water-swellable is water-tight.
Water-proof one-component polyurethane sealant for embedded components in subway construction joints is water-tight.
Water-swellable sealant is water-tight. Performance characteristics of water-stop glue:
Good water-stop effect: it has a double sealing mechanism of elastic water-stop of rubber and slow-swelling water stop when exposed to water. It can withstand maximum water pressure
and has strong durability and quality. Low change rate: It has good chemical stability and can withstand chemicals such as salt water, calcium hydroxide, and has a service life of up to 10 years at room temperature.
, Environmental protection: safe, non-toxic and environmentally friendly product that can be contacted with drinking water
, convenient construction: single-component, paste can use standard caulking adhesive construction equipment
, construction is tight Paste: can be firmly adhered to the concrete surface regardless of whether the base surface is wet, smooth or rough
Good cost performance: performance is better than traditional construction joint waterproofing materials such as steel edge rubber waterstops or waterstop strips at moderate prices.
2. Product use:
Waterproofing of circumferential, longitudinal and horizontal construction joints of various underground structures such as railway tunnels, highway tunnels, urban subways, building underground structures, sewage treatment pools, etc.:
, sealing joints around embedded parts (such as manholes, box-shaped trenches, cable trenches, pipes)
, sealing joints around steel materials
, sealing rough surfaces (such as cement walls) Joints with concrete floors
, strip sealing strips attached to rough surfaces
, sealing bolts or gaps around embedded holes.
3. How to use:
Clean the coating surface to remove dirt
Cut off the front end of the hose according to the width of the coating and pierce the moisture-proof film
Continuously apply the Water-swellable water-stop glue
After application, avoid contact with water until it hardens.
