| | EPX55 is a two-component (A & B) solvent free epoxy filler compound. | | |
| • Welding concrete with other construction materials.
• Embedding steel bars in old reinforced concrete to execute new stairways or balconies, ceilings and extension in old buildings (taking in consideration the structure of the building to withstand the new load).
• Concrete repair and reinforcement.
• Filling holes, voids and surface discontinuities in concrete structures.
• Fixing heavy equipment’s and steel-structure’s elements or frames.
| | |
| • Easy to use.
• Does not flow even if used under elevated temperature.
• Solidification without shrinking or cracks.
• Excellent adhesion to concrete and other materials.
• Excellent abrasion, compression and tensile resistance even in the early stage of application.
• Restores concrete to its original shape.
• Can be applied to fill up to 3cm gaps.
| | |
| | • Method of Application : | By a suitable injection instrument when needed or by a floor trowel, wide bladed putty knife
or by means of rubber gloves. | | • Mixing Ratio : | (by weight)
3 to 1.6 (A to B) | | • Mixing : | The individual components of EPX55 should be thoroughly stirred before the two are mixed together. Combine components (A & B) in supplied proportions and mix thoroughly using a slow speed mixer for at least 3 minutes to achieve uniform consistency; "DO NOT USE HIGH SPEED MIXER". Never mix more material than can be used within potlife. Material that has begun to set must be discarded. | | • Pot life : | Temperatures (° C) Potlife (minutes)
40 10
30 20
20 40
10 90 | | • Thinner / Cleaner : | Do not thin. Due to potlife limitations, clean all mixing equipment and application tools by thinner S405 "known as Epoxsol" immediately after application is completed. | | • Curing : | The reaction between the epoxy and its curing agent (A & B) can not be guaranteed unless a temperature of
at least 10° C is maintained for the mixture and the substrate until complete curing. Temperature of
substrate should be at least 3°C above dew point to avoid moisture condensation during application. |
| | |
| | • Component B : | CAT25 | | • Color : | Gray | | • Volume Solids : | 100 % (ASTM-D2697) | | • Flexibility : | Excellent | | • Recommended film thickness : | 250 microns “dry” | | • Theoretical spreading rate : | 4 m²/L at 250 microns “dry” | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Very good | | • Solvent Resistance : | Very good | | • Number of Coats : | 1-2 | | • Specific Gravity (mixed) : | 1.7 kg/L (ASTM-D1475) | | • Packaging : | Component A “base” 1800 g in US Gallon
Component B “drier” 960 g in US Quart | | • Compressive Strength : | 450-500 kg/cm² | | • Note : | Tensile strength with concrete:35 kg/cm²
Tensile strength with steel :150 kg/cm²
All values are obtained after full cure (7 days at 20° C).
In case of EPX55 is used to embed steel bars in concrete, the table below shows the relationship between the maximum tensile load (taking in consideration the security factor) that can be applied to a various hole depth and diameter of a high resistance steel bars embedded in concrete having a specific cubic resistance of 220Kg/cm².
-Diameter of high resistance steel bars (mm):8 Hole depth (mm):80 Hole diameter (mm):10 Max. tensile load (Kg):2000
-Diameter of high resistance steel bars (mm):10 Hole depth (mm):100 Hole diameter (mm):12 Max. tensile load (Kg):4200
-Diameter of high resistance steel bars (mm):12 Hole depth (mm):110 Hole diameter (mm):14 Max. tensile load (Kg):5500
-Diameter of high resistance steel bars (mm):16 Hole depth (mm):130 Hole diameter (mm):20 Max. tensile load (Kg):8000
-Diameter of high resistance steel bars (mm):20 Hole depth (mm):170 Hole diameter (mm):25 Max. tensile load (Kg):12500 |

| A well-prepared-surfaces is an essential condition of coating successfulness. In general, surface must be clean, dry, undamaged and free of all contaminants prior to coating. Remove fins and other protrusions by stoning, sanding or grinding.
CONCRETE
New concrete: Must be cured at least 28 days at 21?C and 50% RH, or equivalent time.
Old concrete: Abrasive blasting is best to remove all previous coatings, form oils, laitance and other foreign matter.
STEEL
Exposed reinforcing bar should be cleaned to Sa2½ by abrasive blasting in accordance with ISO8501-1. The reinforcement may be coated with 2 brush coats of EPX13 to a minimum dry film thickness of 150µm.
| | |
| | • Dry to Touch : | 4 hours (ASTM-D1640). | | • Dry to Handle : | 24 hours (ASTM-D1640). | | • Fully Cured : | 7 days. |
| | |
| • Epoxy system, in general, especially component B, has to be kept in a cool and well ventilated place, protected from heat and direct sunlight.
• Shelf life is one year from packing date in unopened original containers at 10 to 40°C. Containers should be kept tightly closed.
Safety:
• Well-ventilated conditions should be provided during application.
• Do not breathe or inhale mist.
• Wear air-mask and avoid skin or eye contact.
