Epoxy mortar is generally formulated by epoxy resin, curing agent and add appropriate proportion of cement, quartz sand and other fillers. After curing to meet certain physical and mechanical properties. Can be widely used in road and bridge, water conservancy engineering, waterproofing engineering and other building defects repair and used as seepage leakage materials.

The role of epoxy mortar

• repair repair
• anti-seepage and leakage
• decoration.

Features of epoxy mortar

Epoxy resin itself has good adhesion and bonding, strong mechanical properties, good resistance to acid and alkali and salt spray performance, low curing shrinkage and other advantages, a variety of materials such as concrete has a strong adhesion, with room-temperature curing agent, the appropriate cement, quartz sand and other fillers made of mortar, this mortar has high strength, good adhesion, corrosion, waterproofing, and can be completed curing in a humid environment. It has the advantages of high strength, good adhesion, anti-corrosion, waterproof, and can be cured in wet environment.

The main components of epoxy mortar composition

1.Ordinary bisphenol A type epoxy resin

• YL-128 Epoxy Equivalent (g/eq): 184 ~ 190 Viscosity (cps/25℃): 12000 ~ 15000 Product Description: General standard bisphenol A epoxy resin.

•  YL-127 Epoxy Equivalent (g/eq): 176 ~ 184 Viscosity (cps/25℃): 8000 ~ 11000 Product Description: Low-viscosity standard bisphenol A epoxy resin.

2.Curing agent

Curing agent can be selected from aliphatic primary amine cured at room temperature.

Polyamide

• Viscosity (75°C/mPa s): 3100-3700 Amine value (mgKOH/g): 240-260 Characteristics and applications: High viscosity polyamides for reactive adhesives, solvent based coatings.

• Viscosity (75°C/mPa s): 700-900 Amine value (mgKOH/g): 340-370 Characteristics and applications: medium-viscosity polyamide for reactive adhesives, solvent-borne coatings, mortars

• Viscosity (25°C/mPa s): 700-2000 Amine value (mgKOH/g): 250-290 Characteristics and applications: Used in high solids coatings, very excellent adhesion on wet surfaces

Diethylenetriamine

Diethylenetriamine is a typical representative of vinylamine. Abbreviation: DETA Molecular formula: H2N(C2H4NH)2H Approximate molecular weight: ~103 Active hydrogen equivalent: ~20.6 Reaction with epoxy resin Theoretical dosage: 8~11 parts

3.Filler

Weakly alkaline or neutral hard powder and granule can be used.

Powder can choose quartz powder, silicon powder, cement, etc.; granular material can choose quartz sand, hard river sand, etc.

Typical applications of epoxy mortar:

• Used as concrete structure repair and repair.

Such as high-speed roads, water conservancy projects, bridges, culverts, tunnels and other building defects repair and reinforcement.

• Used as tile, marble, granite bonding material.

• Used for steel structure and concrete bonding. Such as steel adhesive.

• Used in chemical industry, petroleum, marine industry, wharf and other concrete structure of anti-corrosion protection and repair.

• Used for underground pipelines, hydroelectric power stations, dams and other buildings sealing anticorrosion and waterproof seepage treatment.

• Used as landscape decoration. Such as landscape walkway paving materials, wear-resistant flooring.
