Type
Suggested use
As a rehabilitation and high performance lining for thinned/
corroded pipes and where additional tensile properties are required,
Corrocoat Fibrecoat may be applied in single or multiple layers at up to 118 mils (3000 microns) per coat.
Health & safety
Before handling or using this product the material safety data sheet should be
read and all precautions observed.
Chemical resistance
Refer to the chemical resistance list. Affected by some highly polar solvents and some solutions having a high pH above 122°F (50°C).
Surface preparation
Metals: The surface must be decontaminated, degreased and loose materials removed from the surface. Where possible and for optimum performance, grit blast to SSPC–SP10 (ISO standard 8501-1 Sa 2½) or equivalent. (For full details refer to Corrocoat Surface Preparation SP1.)
Application equipment
Airless pump of 45:1 ratio or greater. Fit leather and PTFE seal combination and remove all fluid filters. Fibrecoat is designed to be applied using the Agmec Pipe-sprayer.Refer to Corrocoat Technical Services for further instructions.Brush applicationis not recommended.
Mixing
Weigh out only the proportion of material which can be used
within the pot life and place into a suitable mixing container.
Measure the correct proportion of catalyst for the amount of
base and carefully add this to the base using a suitable clean
implement. Mix thoroughly then add dye where necessary
and mix to an even color.
Storage life
Base and catalyst (Hardener) 6 months, stored at temperatures below 68°F (20°C), away from heat sourcesand out of direct sunlight. Frequent temperature cycling will shorten storage life. See ‘other information’ in the Corrocoat ‘Tech Manual’ for extension of shelf life.
Color availability
Std. Off-White or Translucent Brown. Other colors are available on request but the addition of dyes adversely affects chemical resistance and air
inhibition suppressant is required for color stability.
Theoretical spreading rate
13 sf per gal at 118 mils (0.33m²/litre at 3000 microns)
Volume solids
This material contains volatile liquid convertible to solids. Volume solids obtained will vary dependent upon
polymerization conditions. Nominally 99% of the product is convertible to solid.
Practical spreading rate
10 sf per gal at 118 mils (0.25m²/litre at 3,000 microns). NOTE: This information is given in good faith but rate may vary significantly dependent upon environmental
conditions, the geometry, and the nature of work undertaken and theskill and care of application. Corrocoat accepts no responsibility for any deviation from this value.
Specific gravity
Corrocoat Fibrecoat base: 0.04lbs/cubic inch (1.11 gms/cc). Hardener: 0.03lbs/cubic inch (1.07 gms/cc).
Catalyst type
Methyl Ethyl Ketone Peroxide, type P2-45.
Curing time
With standard inhibitor level, tack free circa 6 hours, full cure 3-4 days at 68°F (20°C), but may be immersed in many environments after 24 hours.
Cleaning fluid
Methyl Ethyl Ketone, Methyl Iso Butyl Ketone – before gel.
Application
Dependent on intended use and site conditions, Corrocoat Fibrecoat is normally applied direct to the surface wet on wet at films >118 mils (3000 microns). Single coat applications are recommended
Recommended DFT
Greater than 118mils (3000 microns) dependent upon duty and environment. This material is a barrier coating and the thickness needed is dependent upon serviceconditions and the existing condition of the substrate
Mixing ratio / mixing
98:2 base to hardener. For inhibitor use and mixing instructions refer to Polyglass Application Data Sheet. Adding inhibitor after the catalyst will ruin the product.
Pot life
Circa 2 hours at 68°F (20°C) but may be varied by use of inhibitor or special manufacture for low applicationtemperatures, refer to Polyglass Application Data Sheet.
Thinners
Corrocoat Fibrecoat is adversely affected by the addition of solvents and their use is prohibited. Thinning can be achieved by the addition of no more than 0.25 gal (1 liter)of styrene monomer per 5.25 gal (20 liters) of base. It should be noted that dilution with styrene mayaffecthold upand chemical resistance.
Packaging
1 Gallon and 5 Gallon Kits
Mixing ratio
98:2 base to hardener, refer to Application Data Sheet for inhibitor levels.
Flash point
82°F (28°C).
Hardness
45 Barcol after full cure.
Cathodic disbondment
0-1mm.
Adhesion
> 10 MPa (ASTM D4541).
Temperature limits
194°F (90°C) immersed. 320°F (160°C) non-immersed. No known lower limit.
Abrasion resistance
137 mg loss/1000 cycles/1000 gm load. (H18 wheel)
Overcoating
It is important to observe maximum over coating times and note these will vary
substantially with climatic conditions.Minimum, as soon as gel has occurred and while still tacky. Maximum, at 68°F (20°C) 48 hours. Strong ultra-violet/sunlightwill substantially reduce over coating time. Once
maximumover coating time has been reached, adhesion values attained by any subsequent coat will reduce dramatically. Should this occur over coating should be treated as a repair,with the coating flash blasted to provide a physical key. Styrene cannot be used to reactivate the surface of thisproduct and may impair adhesion. Take care to avoidcontamination before application of subsequent coats. Ensure ventilation during cure.
