Construction Columns Retrofitting Steel Epoxy Adhesive With High
Strength
XQ-JGN Steel Epoxy Adhesive
JGN Steel epoxy adhesive is a two component epoxy resin adhesive
which has features as bonding with all kinds of base materials
(cements, stones, bricks etc.), high strength, strong anchoring,
metal and steel plates, fast curing, good acid and alkaline
resistance, ageing resistance, etc. Widely used for bonding and
reinforcement for conrete with stone and steel plates, as well as
all kinds of section units. Good stability within expected period,
suitable for heavy section units.
Range of Application
Anchoring reinforcement for water conservancy facilities,
bridges,docks, roads, and other projects
Repairing and reinforcement for all building of industry and
residence, bridge, tunnel, etc.
Reinforcement for all kinds building structures, and steel bonding
reinforcement of walls, floors, beams and poles etc.
Features
Good acid and alkali resistance, aging resistance, low moisture
sensitivity;
Can be used in wide temperature range, no precipitation;
Two component, modified epoxy rein, fast curing at room
temperature, good bonding strength, stable mechanical properties
Free base layer adhesive, easy to handle and reduces the effect of
construction technology on mechanical properties;
For bonding between same or different materials of metal, ceramics,
plastic, rubber, wood etc.
Excellent thixotropic performance, easy to paint and avoid
hollowing and waste;

Processing Flow
- Anchoring
- Maintenance
- Positioning
- Base materials treatment
- Cleaning
- Mixing the adhesive
- Painting
Positioning: mark the steel bonding position;
Base material treatment: Remove the painting layer on concrete surface and to drill derust
and polish the steel;
Cleaning: using compressed air to blow the surface from dust, clean with
acetone;
Mixing the adhesive: according to the weight ratio of A:B=3:1, weigh and mix in the
barrel;
Painting: paint the above mixed adhesive onto the surface of concrete and
steel plate, do not have bubbles inside;
Anchoring: attach the steel plate directly on the surface of coated
concrete, remove the surrounding excess adhesive,then fix with
steel frame;
Maintenance: fix for conservation at room temperature no less than 24 hours.
