What is Concrete Joint Sealant
Concrete Joint Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the gap of the configuration to play a sealing role. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation, and heat insulation.
It is usually made of dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, etc., combined with inert fillers such as talcum powder, white clay, carbon black, titanium dioxide and asbestos, and then added with plasticizers, solvents, curing agents, accelerators, etc.
Types of Concrete Joint Sealant
Polysulfide sealant is a sealant made of liquid polysulfide rubber as the main material, combined with tackifying resin, vulcanizer, accelerator, reinforcing agent, etc. This type of sealant has excellent resistance to fuel, hydraulic oil, water and various chemicals, as well as heat resistance and atmospheric aging resistance.
One-component polyurethane sealant is a solvent-free, one-component, room-temperature curing sealant. The sealant is in paste form and can be extruded or applied. It has anti-sagging properties and fills vertical joints and top joints without flowing. The cured adhesive layer is rubber-like and elastic. It has adhesion to metal, rubber, wood, cement components, ceramics, glass, etc.
Water-swelling water-stop glue Super Water-stop Material PJ220 and PJ400 are water-swelling single-component sealants that are excellent in construction performance. Once hardened, they become a rubber elastic body with good recovery properties. When immersed in water, their volume expands and fills the gaps to exert a reliable water-stopping effect. As a water-stop material around waterways in civil engineering and construction projects, it can exert excellent performance and has a wide range of uses.

1. During manual construction, weigh components A and B in proportion (10:1) and mix them evenly with a putty knife, fill them into the sealing groove, compact, fill and remove excess glue. Pay attention to repeatedly scraping in one direction to prevent a large number of bubbles from mixing into the glue.
2. During mechanical construction, the glue is mixed by an automatic metering and mixing device (10:1), and the glue amount and speed are controlled by a manual injection gun or a fully automatic glue sprayer. When using a glue injection gun, hold the gun nozzle and move it at a uniform speed in one direction to ensure that the glue is filled to prevent bubbles from moving too fast or reciprocating.
3. Precautions:
It cannot be mixed with silicone sealant, otherwise it will affect its bonding performance.
The construction temperature is above 5°C, otherwise it will affect its bonding and curing speed.
Do a small sample test before construction.
1. Wide adjustable performance range and strong adaptability;
2. Good wear resistance;
3. High mechanical strength;
4. Good bonding performance;
5. Good elasticity, excellent recovery, can be used for dynamic joints;
6. Good low-temperature flexibility;
7. Good weather resistance, service life up to 15~20 years;
8. Good oil resistance;
9. Resistant to biological aging;
10. Moderate price.
1. Since it is a single-component type that hardens when wet, it has excellent workability.
2. It expands when exposed to water, and can more reliably exert the water-stopping effect.
3. It has good adhesion to concrete, metal, glass, etc.
4. Water expansion test conditions
● After hardening (after 7 days), soak in water and measure its volume increase rate.
● Test piece size: 40X2X40mm
● Water temperature: 20±5℃
The expansion rate varies depending on the shape of the coating section.
Application of Polysulfide Sealant
Polysulfide sealant is suitable for waterproof sealing of hollow glass, metal and concrete curtain wall joints, underground projects (such as tunnels and culverts), reservoirs, water storage tanks and other structures.
Polysulfide sealantas also used in expansion and expansion joints of highway pavements, runways, etc., and repair and restore the sealing of building cracks.
Keep away from fire sources and avoid ventilation.The temperature is 5℃～30℃.
Application of Polyurethane Sealant
Polyurethane glue has a high elongation of more than 3 times and a bonding strength of more than 2 times. After the single-component polyurethane glue is fully cured, it is non-toxic and can be used in drinking water projects. It has been authoritatively tested. Polyurethane sealants are widely used in civil engineering, transportation and other industries:
1. Application in construction – filling and sealing of doors, windows, glass, etc.;
2. Application in civil engineering – caulking and sealing of highways, bridges, runways, etc.;
3. Application in automobiles – assembly and sealing of car windows (mainly windshields).
Application of Swelling Waterstop Sealant
Water-swellable waterproofing glue is a water-swellable single-component sealant that is a waterproof material with excellent construction performance. Once hardened, it becomes a rubber elastic body with good recovery properties.
When immersed in water, its volume expands and fills the gaps to exert a reliable waterproofing effect.
It can exert excellent performance as a waterproof material around waterways in civil engineering and construction projects, and has a wide range of uses.
