Description
Main Feature
Good penetration and adhesion to porous substrates such as concrete
Strong adhesion, forming a physical anchor state with the cement base after curing
High solid content, low VOC emissions and low odor
Not suitable for surfaces with very smooth and dense surfaces that cannot be sanded to open pores and achieve penetration.
Detailed introduction
E811 solvent-free epoxy primer is a solvent-free epoxy resin varnish, which is composed of liquid epoxy resin, low viscosity curing agent and monofunctional small molecule epoxy.
Application scope
This product can be used as a sealing primer on concrete, terrazzo or other base surfaces in industrial plants, warehouses, underground parking lots, offices, etc.
This product can also be used as a material for repairing damaged foundation floor expansion joints.
Product Information
The material is divided into two components: A and B.
Component A transparent liquid 20kg/barrel
Component B brown-red liquid 10kg/barrel
Ratio: A component: B component = 2:1
Packaging: Printed metal packaging drum. It is recommended to stack it in three layers when stacking.
Storage: The storage temperature is 5-35℃. It should be stored in a cool, ventilated and dry warehouse.
Keep away from fire and heat sources, and strictly prohibited from exposure to the sun
Technical data
Status: Uniform, no lumps, no impurities
Bonding strength: ≥2.5MPa
Drying time: Surface dry: less than 4 hours

(Temperature is 25℃, relative humidity is 50%)
Grassroots requirements
The compressive strength of the concrete floor should be ≥20Mpa, the tensile strength should be ≥1.5Mpa, and the flatness should be ±4mm/2m by ruler. The base surface must be dry, clean, and free of oil and other contaminants. Base treatment
Construction Conditions
Ground base temperature: 5-35℃
Construction environment temperature: 5-35℃
Ground base moisture content: <8%
Relative humidity of construction environment: <80%
Construction methods/tools
Dilution: 0-30%
Construction method: Roller coating, scraping coating, spraying can be used. Pay attention to even application without accumulation or leakage.
Tools: push knife, roller brush
Instructions for use
Surface treatment: Before construction, dust, sand, cement laitance, grease, old coatings, etc. should be removed from the base surface, and polished to form a rough surface to open the capillary pores on the base surface.
Theoretical dosage: about 0.15 kg/square meter
Ratio: A:B=2:1 (weight ratio), mix evenly before construction.
Opening time: Materials A and B should be used within 20 minutes after mixing. If the viscosity of the material is found to be significantly increased, it cannot be used anymore and should be discarded.
Precautions
1. For the safe use of the product, please request the product safety data sheet (MSDS) from the manufacturer.
