Epoxy resin bonded steel adhesive JGN modified epoxy resin bonded steel adhesive

  JGN epoxy resin pouring steel adhesive jgn801 steel adhesive is a two-component modified epoxy resin structural adhesive
The adhesive is divided into three specifications: normal temperature curing type, low temperature (- 10 ℃) curing type and wet environment (or underwater) curing type

Jgn803 pouring steel bonding adhesive is a two-component modified epoxy structural adhesive
It is a special adhesive suitable for fixing first and then pouring steel bonding
It is mainly used for pouring construction of high-strength bonding surface

1、 Product features
· No crystallization during winter construction and no extension of curing time (low temperature type)

· Good operability, no layering, no segregation, no precipitation, good thixotropy, no flow in construction, which can save the amount of glue

· With complete types, it can solve the construction technical problems under various harsh conditions (low temperature, high temperature, wet surface and underwater)

· The material has high strength, excellent aging resistance and medium resistance (acid, alkali and salt)

· High bonding strength, good toughness, earthquake resistance and impact resistance

· The material is green and environment-friendly, does not contain volatile solvents, and is safe and non-toxic

4、 Scope of application
Steel adhesive
· Bonding and reinforcement of steel plates by concrete members, masonry members and wood members

· Curtain wall installation, bonding and installation of marble, granite, ceramic tile, etc

· Repair and bonding of concrete members and steel members

Pouring steel glue
· Concrete components are reinforced with wet wrapped steel plates, and large-area steel plates are poured and bonded outside bridges and other components
· Grouting repair of concrete cracks (1-5mm) and internal defects (honeycomb and holes)

· Anchor bolts, secondary grouting of equipment base plate and epoxy resin self flowing floor construction

5、 Instructions for use
Steel adhesive
· Clean the surface of the substrate: polish the bonding roller to remove the laitance and loose layer on the surface, expose the new surface, blow off the dust with an air compressor, and then remove the dirt with acetone

· Derusting of steel plate surface: sand blasting, abrasive cloth or steel wire brush can be used for grinding and polishing until metallic luster appears

· Weigh the required amount according to a ∶ B = 3 ∶ 1, mix it fully, apply it on the surface of the steel plate to be bonded, the thickness is 1-3mm, and make the middle of the adhesive layer thick and the edge thin

· After the steel plate is pasted in place, it shall be fixed with chemical anchor bolts or expansion bolts immediately and properly pressurized

· Do not move the adhesive before the adhesive is cured, so as not to affect the bonding effect

Pouring steel glue
· Clean the surface of the substrate: polish the bonding roller to remove the laitance and loose layer on the surface, expose the new surface, blow off the dust with a compressor, and then remove the dirt with acetone

· Derusting of steel plate surface: sand blasting, abrasive cloth or steel wheel can be used for grinding until metallic luster appears

· According to the design requirements, the steel shall be placed in place and welded, and then the gap between steel and concrete shall be sealed with joint sealant or epoxy repair mortar
The rubber injection pipe and exhaust pipe must be buried in appropriate positions

· Weigh the required amount according to the proportion, mix it fully, pour the mixed steel glue into the pressure pump and start the machine for pouring
Glue injection sequence shall be from bottom to top

Do not move the adhesive before the adhesive is cured, so as not to affect the bonding effect

· According to the weight ratio: a ∶ B = 3 ∶ 1& middot; Reference dosage: 5~7Kg/ m2
