Description

Carboline Plasite 4550 S is a two-component, 100% solids, flake filled, premium novolac epoxy coating designed for internal steel and concrete substrates. It is a two-component system consisting of four-parts by volume of Part A resin and one part by volume of Part B hardener. It is applied by plural component or single component spray equipment, from a total thickness of 500-1500 microns in a single coat application for a variety of applications. This product has been tested and is approved for crude oil storage and transportation up to 177°C (350°F).

It has superior thermal shock resistance over the range -40 to 177°C (-40° to 350°F). Typical Uses: Crude oil tankers, chemical storage tanks, wastewater clarifiers, plating vats, oil storage tanks, catwalks, pulp and paper liquor tanks or concrete exposures in wastewater applications.

VOC Values: As Supplied: 0 g/L
Dry Temp. Resistance:

Non-Continuous: 204°C (400°F)

The film build (per coat) will decrease with age of the part A as follows but the cure mechanism and performance is not affected 3 months or less: Over 1524 microns (60 mils) is typical 3-6 months: 762-1270 microns (30-50 mils) is typical 6 months or older: Can be less than 762 microns (30 mils)

Follow intercoat preparation requirements when applying multiple coats

Storage Temperature:

10-29°C (50-85°F)

For 24-48 hours prior to use narrow the storage temperature to 21-29°C (70-85°F) to facilitate ease of mixing



Drying Times


Curing Schedule
Surface Temp Dry to Handle Final Cure Immersion
10°C (50°F) 30 Hours 7 Days
16°C (60°F) 24 Hours 4 Days
24°C (75°F) 12 Hours 36 Hours
32°C (90°F) 4 Hours 24 Hours



  • * And 50% relative humidity @ 24°C (75°F): dry to touch in 12 hours, firm dry in 24 hours
  • Final cure above is for mild immersion service
  • Epoxies may form amine blush under some curing conditions. Blush must be removed before coating or placing in some services



Surface Preparation


General

  • Surfaces must be clean and dry
  • Employ adequate methods to remove dirt, dust, oil and all other contaminants that could interfere with adhesion of the coating

Steel

  • Immersion: Prepare by abrasive blasting to a minimum near White Metal Finish (NACE NO 2, SSPC-SP10) with a minimum 75 micron (3 mil) dense, sharp anchor profile
  • For special applications involving stainless steel used in wet FGD applications a minimum of 50 microns (2 mils) dense angular anchor profile is acceptable

Concrete or CMU

  • Clean, dry and remove all loose, unsound concrete
  • Do not apply coating unless concrete has cured at least 28 days @ 21°C (70°F) or equivalent
  • Prepare surfaces in accordance with SSPCSP13/NACE No. 6 Surface Prep of Concrete
  • Voids in concrete may require filling and/or surfacing
  • Consult Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for recommended primer/sealer



Application Methods


Product Information
Mixing: Mix each component separately to a smooth, uniform consistency. Any settling in the container must be thoroughly scraped and re-dispersed. Use a Jiffy type mixer and avoid plunging it up and down in the bucket, which can fold air into the resin causing bubbles to form in the coating after it has been applied

For touch-up only:

Jiffy type mixers are recommended for all mixing and stirring. Avoid plunging the mixer up and down in the bucket. This can fold air into the resin which may cause bubbles to form in the coating after it has been applied. Individually stir separately Part A and Part B to a smooth uniform consistency and colour. Any sediment in the container must be thoroughly scraped up and re-dispersed

Thinning: Thinning not normally required. Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied
Pot Life:  24°C (75°F): 45-60 minutes
General:

Lining Repair:

Before any touch up or recoat material can be applied the first coat must be properly prepared for intercoat adhesion. The first coat must be cured firm to touch. Coating on floors must be able to support foot traffic. Scrub the first coat with soap and water and thoroughly rinse and dry

If the first coat cures more than 24 hours, sand or mechanically abrade the surface after scrubbing it down. Any surface to be touched up or recoated should be protected. When the recoat material is applied the surface must be dry and free of all dirt, dust, debris, oil, grease or other contamination

Airless Spray:

Use air motor with an air ratio of 42:1 or larger

All filters should be removed from the pump. Use a 3/8 in. spray hose from pump to gun, not to exceed 100 linear ft

It is best to bring the material directly to the gun body and not go through a tube in the handle. The size of airless spray tip should be from 0.019-0.035 inches

The mixed material temperature should be 24-38°C/75-85°F for best spraying properties. Temperatures above 29°C (85°F) will shorten pot life

Immediately before applying spray coat, stripe all continuous welds and edges with a brush coat to assure adequate protection of these areas

Apply material to specified thickness using 200-350 microns (8-14 mil) per pass

Apply in a crisscross, multi-pass technique, moving gun at a fairly rapid rate and maintaining a wet-appearing film

Use a wet film gauge to monitor film build

Plural Component Airless Spray:

Use a fixed (4:1) ratio plural component spray rig with heated hoppers, heated hoses to a mixer manifold through a static mixer to a 50 ft whip hose and self-cleaning reversible tips from 0.017" to 0.035"

The Part A material should be a minimum of 43°C (110°F) and the Part B should be  32-38°C (90-100°F). Take care to prevent mixed material from setting up in your hoses

For best results keep hoses as short as possible, purge them immediately with Carboline Thinner 76 if work is interrupted, keep them out of direct sunlight and insulated from hot surfaces



Application Conditions


Product Conditions
Condition Material Surface Ambient Humidity
Minimum 24°C (75°F) 10°C (50°F) 10°C (50°F) 0%
Maximum 29°C (85°F) 52°C (125°F) 32°C (90°F) 85%



  • Do not apply material when temperature will fall within 3°C (5°F) of the dew point
  • Material temperatures listed above are optimal for standard airless spray. For plural spray: Part A should be a minimum of 43°C (110°F) and Part B 32-37°C (90-100°F)



Health and Safety


Clean Up

Safety

  • Read and follow all caution statements on this product data sheet and on the safety data sheets for this product and use personal protective equipment as directed
  • Employ normal workmanlike safety precautions

Ventilation

  • When used in enclosed areas, thorough air circulation must be used during and after application until the coating is cured.
  • The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used
  • User should test and monitor exposure levels to ensure all personnel are below guidelines
  • If not sure or if not able to monitor levels, use MSHA/NIOSH approved supplied air respirator

Caution

  • Fire and explosion hazards: This product contains less than 1% volatile components, however, vapours are heavier than air and can travel long distances, ignite and flash back
  • Eliminate all Ignitions sources. Keep away from sparks and open flames
  • All electrical equipment and installations should be made and grounded in accordance with applicable local regulations
  • In areas where explosion hazards exist, workers should be required to use non-ferrous tools and wear conductive and non-sparking shoes
  • Refer to the product data sheet and safety data sheet in the attachments section above for further details
