Description

Carboline Carboweld 11 is a weldable pre-construction inorganic zinc primer for shop use only. Designed to protect steel during construction phase of projects under normal conditions, Carboweld 11 can be topcoated for additional long-term protection for atmospheric exposures.

Welds made over Carboweld 11 coated steel are equal in every respect to welds made to uncoated steel. Can be welded as quickly and easily as bare steel at production line speeds without loss in strength or consistency of the weld.

For shop use only

Flash Point: 11°C for Base
Shelf Life: Part A: 18 months at 24°C
Part B: 24 months at 24°C
Storage Temperature and Humidity: 4°-43°C
0-95% Relative Humidity



Drying Times


Curing Schedule
Surface Temp Dry to Handle Final Cure General
-18°C 2 Hours 5 Days
4°C 40 Minutes 12 Hours
16°C 15 Minutes 6 Hours
27°C 5 Minutes 4 Hours
38°C 3 Minutes 2 Hours



  • Drying times are based on a 20-40 micron dry film thickness. Higher film thickness, insufficient ventilation or cooler temperatures will require longer cure times and could result in solvent entrapment and premature failure
  • For shop applications or if the relative humidity is too low, the curing time can be reduced by raising the relative humidity by steam or water spray on the coated surface after an initial dry time of 1 hour at 24°C



Surface Preparation


General

  • Remove all oil or grease from the surface to be coated with Thinner 2 or Surface Cleaner 3 (refer to Surface Cleaner 3 Instructions) in accordance with SSPC-SP1

Steel

  • Abrasive blast to achieve a sharp angular profile of 1.0-1.5 mils for most applications. Where high build topcoats are used; 1.5-2.5 mil blast profile is recommended

Stainless Steel

  • Abrasive blast to a 1-1.5 mil profile and apply material direct to substrate or over appropriate nonzinc primer
  • Immersion (see Limitations): SSPC-SP10
  • Non-Immersion: SSPC-SP6

Welding Data

  • Automatic- Carboweld 11 when applied at recommended thickness may be welded at speeds up to 48” per minute. This is dependent upon plate thickness and bead size. This includes the following processes: 1) Submerged arc 2) Flux core 3) Short arc and 4) Metal Inert Gas (MIG)



Application Methods


Product Information
Mixing: Power mix base, then combine parts, sifting zinc filler slowly into base and mixing with continuous agitation. Mix until free of lumps. Pour mixture through 30 mesh screen
Do not mix partial kits
Keep under mild agitation during application
Thinning: Not normally required, but may be thinned up to 25.6 ounces per gallon with Thinner 21 in cool weather (below 4°C)
For hot or windy conditions, use Thinner 33 up to 25.6 ounces per gallon
Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether express or implied
Ratio:

3 Gal Kit

Part A (Base): One 5-gal can (partially filled)

Part B (Zinc Filler Type II): 14.6 lb unit (6.6 kg)

15 Gal Kit

Part A (Base): Three 5-gal cans (partially filled)

Part B (Zinc Filler Type II): 73 lb. unit (33.1 kg)

Pot Life: 48 Hours at 24°C and less at higher temperatures. Pot life ends when coating becomes too viscous to use
Spray Application: Agitate the mixed material continuously during the spraying operation. If spraying stops for more than 15 minutes, recirculate the material remaining in the spray line
Conventional Spray: Pressure pot with dual regulators, agitator, 3/8” I.D. minimum hose, 50’ maximum material hose length .070” I.D. fluid tip and appropriate air cap. Keep pot at same level as application
Airless Spray: Pump Ratio: 30:1 min
Volume Output: 3.0 gpm min
Material Hose: 3/8” I.D. min
Tip Size: .019-.023”
Output PSI: 1500-2000
Filter Size: 60 mesh
Brush: For touch up of areas less than one square foot only. Use medium bristle brush and avoid over brushing
Roller: Do not apply by roller

  • This product simply requires the substrate temperature to be above the dew point
  • Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate
  • Special application techniques may be required above or below normal application conditions



Health and Safety


Clean Up

  • Use Thinner 21 or Isopropanol
  • In case of spillage, absorb and dispose of in accordance with local applicable regulations

Safety

  • Read and follow all caution statements on this product data sheet and on the safety data sheet for this product and use personal protective equipment as directed
  • Employ normal workmanlike safety precautions
  • Hypersensitive persons should wear protective clothing, gloves and use protective cream on face, hands, and all exposed areas

Ventilation

  • When used as a tank lining or 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 insure all personnel are below guidelines
  • If not sure or if not able to monitor levels, use MSHA/NIOSH approved respirator

It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.
