Water emulsion epoxy resin Mortar:
Made from emulsion epoxy resin cement High quality mineral aggregates, organic additives and synthetic polymers. It can ensure the early and final strength of mortar and other materials used for repair concrete Important performance required, suitable for repairing a steel bar The concrete peeling caused by corrosion can repair the defects of general concrete components, such as honeycomb holes and cement slurry loss. Some epoxy mortar is only used for aesthetic reasons to make decorative repairs to the concrete without reinforcement and without bearing function, while others are used to maintain and re-establish its structural stability and function and repair the damaged load-bearing reinforced concrete structure. Epoxy resin mortar is a part of the concrete repair system, which is used for repair and restoration of roads and bridges, parking lots, tunnels, chimneys, sewage pools, etc.
characteristic:
·High compressive strength, rapid curing
·Good bonding performance and firm old and new bonding surface
·High temperature resistance and thermal shock resistance
·Wet base construction
Application:
· Anti erosion, anti cavitation, anti freezing and thawing protection of hydraulic structure flow surface, and repair after damage.
· Anti wear protection and repair of roads, bridges, airport runways, workshops and other engineering parts.
· Chemical, petroleum, factory, wharf and other concrete or Metal Protection and repair of components against acid, alkali and salt corrosion.
· Reinforcement of cracks, holes, spalling and other parts of buildings, and repair of defects such as concrete honeycomb, loopholes, cracks, damaged protective layer and missing reinforcement.

Product construction
·Material preparation: Material A: Material B: Material C=1:3:16. First pour material A and material B into the bucket in a ratio of 1:3 and mix them evenly, then slowly add material C while stirring until they are mixed into a uniform mortar shape. be careful: (1) Materials A and B may be slightly layered after being stored for a long time. They should be shaken well before use. (2) It is strictly prohibited to use the mortar that is not mixed evenly or has been in the initial setting state.
· Construction:
A 、 Local repair of defect:
According to the construction requirements of the project, the prepared daub shall be applied to the repaired part with a spatula. When applying, it shall be compacted and polished at the same time. It can be put into use 7 days after completion.
B 、 Large area integral surface plastering construction:
When used as an integral surface course, the thickness shall not be less than 3mm steel structure The whole surface layer shall be made twice on the surface of. The interval between each time shall not be less than 24h. When the next plastering of * * is carried out, it shall be leveled at one time, and repeated plastering is not allowed.
C Construction of ground abrasion resistance improvement treatment:
Apply the mixed glue on the ground to be repaired, and the thickness should not be less than 3mm. No maintenance is required after construction. People can get on for 2-3 days, and heavy loads can be loaded after 7 days.
packing
· packing: The packaging specification is 20kg/barrel, or (15kg+45kg+240kg)/group.
· Storage: Stored in a dry and ventilated environment, waterproof and moisture-proof, the shelf life is 6 months when unopened, and can be transported as general goods. Epoxy mortar, epoxy mastic, epoxy mortar
Cement self leveling is a kind of polymer mortar. Its main raw material is cement, and its environmental performance is very good Epoxy mastic Its main component is emulsified epoxy resin, so this is not the same thing at all!
