FC900-4 Epoxy Self-leveling Antistatic Floor Coating

Product Overview

Modern industry develops towards the direction of automation and electronic; high science and technology enterprise and key laboratory have very high requirements for ground environment, this not only requires ground to have anti-static function, but also requires ground to have high wear-resistance, epoxy self-leveling antistatic coating system can meet these requirements, and realize such three of high wear-resistance, high impact-resistance and antistatic into one.

Application scope

◇ Ground system of special locations for chemistry, powder, organic solvent production, operating room and computer room.
◇ Enterprise workshop ground of computer, electron, microelectrorics, precision instrument manufacturing, confidential machinery manufacturing, electrical communication, communication, printing, military industry and aerospace, etc.

Performance characteristics

◇ With evelasting antistatic effect.
◇ Leak electrostatic charge rapidly.
◇ With all excellent functions of epoxy self-leveling floor.

System characteristics

◇ Non solvent type, two components, various colors, light or matte.
◇ Thickness 1-5mm.
◇ General service life is 8-15 years.

Construction Process

Process name	Specific practices and requirements	Reference application amount
Close layer	1.Use epoxy self-leveling antistatic close primer: Mix master paint and curing agent by proportion and stir them evenly; 2.Use scraper to conduct closed screeding.	0.15-0.20kg/m²
Intermediate coating mortar	1.Use floating coating of non-solvent epoxy paint: adding appropriate quartz powder of 40-100 meshes to stir evenly after mixing master paint and curing agent by proportion; 2.Use scraper to scrape the whole for 1-2 times. 3.After cure, grind defect like scrapping mark with clean treatment.	0.16-1.2kg/m²/mm
Grounding copper network	Lay copper wire or copper foil according to requirement and use conductive putty to scrape and fill seams.	Interval 2m×2m
Priming coat	1.Use epoxy antistatic primer: Mix master paint and curing agent by proportion and stir them evenly; 2.Use roller and hairbrush to paint evenly, without holidays; 3.Use hairbrush to paint in door edge, wall corner, wall foot and machine foot.	0.15-0.20kg/m²
Top coating layer	1.Use epoxy self-leveling antistatic primer: Mix master paint and curing agent by proportion and stir them evenly; 2.Use prepared trowel to conduct self-leveling flat trowel surface or use airless sprayer to spray.	0.8-1kg/m²

Construction Planing Surface

Base Surface Treatment

1.New cement floor: New cement floor shall be maintained for more than 4 weeks generally. In summer it needs more than 2 weeks, guaranteeing moisture to volaillize adequately, moisture content is less than or equal to 8% and concrete solidifies completely.
2.Old floor: Whether ground intensity satisfies the conditions of paving epoxy floor; vacant shell and peeling on base surface must be broken and removed throughly until floor is hard and film. Original coating shall be tested to see whether it is compatible with the floor coating to be painted so as to decide whether to construct directly or construct after removing it throughly.
3.Damaged area: Before painting primer, use epoxy mortar to repair smoothly and throughly consider its bonding strength and intensity.
4.Ensure construction ground to be clean, dry and film without dust.
5.The ground with oil stain shall be clean with orgainc solvents and wiped dry ,if these solvents are not be obtained, a cement mortar layer can be laid on it directly again.
6.Wall corner or other places not required to be plastered shall be affixed with pink tape for protection to avoid painting.

Notes

1.Construction temperature: ≥5℃
2.Ensure air to flow when construction, and the prepartion time for application amount shall not exceed 30min.
3.Maintenance shall be done will during construction and avoid dust and sundries intruding so as to affect coating effect.
4.After construction, it shall be maintained for atleast 7 days then can be put into use; during maintenance, it shall be nout soaked by water or all kinds of solvents.
5. It is strictly prohibited to interfuse other coating.
6.Curing agent shall be added according to specified proportion strictly.
7.Keep painted object surface clean and moisture of painted object must be less than 7%.
8.Maintain coating environment clean, and prohibit constructing under environment with a large number of dusts.
