 Product Description

Benco #B17 Industrial Paint Remover / Powder Coatings Stripper (5 Gallon Drum)

 b17.png

#B17 is the most effective product available for the removal of powder coatings.

 

Retains stripping effectiveness better than any other available product.

Will strip most coatings in a small fraction of the time required by all other products.

Has the added benefit of being used at room temperature and requiring no heating to increase effectiveness.

Typical strip time for most powder coating is 5-15 minutes for complete delamination and removal of the coating.

Strips in less than 10% of the time required for blast stripping without damage of the substrate caused by blasting.

INTRODUCTION

  • Benco #B17 Industrial Paint Remover is a liquid, non-flammable remover widely used to remove durable coatings from steel and aluminum. #B17 is the most aggressive formulation developed by Benco Sales for the removal of technologically advanced coatings designed for extreme durability and chemical resistance. Epoxy coatings, powder coatings, electrocoat coatings, polyurethanes, and UV/EB coatings are rapidly removed by submersion in #B17. #B17 is also effective on recently developed ceramic coatings.
  • #B17 is an acidic solution containing methylene chloride and phenol. #B17 is also formulated with ingredients that limit evaporation and that provide formulation stability, allowing the product to be extensively used and reused without performance deterioration. #B17 can be used in temperatures ranging from 35 degrees F to 100 degrees F. The product will begin to boil at 104 degrees F and will not freeze. #B17 was developed more than 15 years ago and has been an effective stripping solution on coatings not able to be stripped by other products or only stripped by blasting with abrasives.

 

USES

  • #B17 is the most effective product available for the removal of powder coatings. It is a stable, non-flammable product used at room temperature. With most coatings, the removal process involves rapid swelling of the coating and delamination from the substrate, although there are a few coatings that are removed by dissolving the coating. Since most coatings are delaminated, they are easily removed from the stripping bath, and when dried will not contain residue of the stripper. Typical strip time for most powder coating is 5-15 minutes for complete delamination and removal of the coating. There should be no agitation of the stripping bath. It is not necessary to remove the stripped coating from the bath, as the stripped coatings will not affect stripping effectiveness of #B17. The best time to removed stripped coatings is when they are affecting operation of the bath. #B17 retains stripping effectiveness better than any other available product and will perform until almost all product is used up by either carry-out or evaporation.  #B17 has the added benefit of being used at room temperature and requiring no heating to increase effectiveness. #B17 will strip most coatings in a small fraction of the time required by all other products capable of removing powder coatings. #B17 strips in less than 10% of the time required for blast stripping without damage of the substrate caused by blasting.
  • #B17 contains a small percentage of VOC’s, and will not contribute significantly to atmospheric pollution through formation of smog, to the depletion of stratospheric ozone, or to global warming.
  • #B17 is most effective when the item to be stripped is immersed in a bath of #B17. #B17 is used at full strength and not diluted. The best receptacle to store #B17 for use is an HDPE container. Blow molded HDPE containers are readily available in all sizes. The container should be covered, but the cover does not need to be airtight. #B17 contains ingredients that limit evaporation, and when air movement over the stripping receptacle is precluded by a cover and the temperature is less than 90 degrees F, the evaporation of the product is substantially limited. #B17 can also be used in a steel receptacle. The minimum gauge recommended is 12 gauge. #B17 should not be used or stored in an aluminum container. The only other appropriate plastic container is HDPP. #B17 will melt most other plastics.
  • #B17 is safe to use on all steel items. It is widely used to strip coatings from aluminum, but will etch aluminum if contact time exceeds 2-3 hours. #B17 is not appropriate for use on magnesium items or on galvanized surfaces because it will rapidly etch these surfaces and may damage them.

 

STRIPPING PROCEDURES

  • Apply Benco #B17 by submerging item in the stripper. Do not apply by a flow or continuous flow pump system. Application by brush may be appropriate for smaller items.
  • Immerse and allow product to strip all coatings prior to removal.  
  • For items with multiple coatings, one application will remove multiple coatings. If one application does not remove all coatings, immerse again immediately and residual coatings should be rapidly removed.
  • If the product has dried on the surface, reapply a coat of stripper prior to removal of finish for best results.
  • Stripped finishes can be removed with a scraper or brush, although brushing is not necessary on most items. Removed finishes with stripper can be reapplied to extend the life of the stripper.
  • For best results, once finishes are removed from the surface, rinse with water.
  • Do not use on magnesium surfaces.
  • Use extreme caution with this product, as it will severely burn skin and eyes on contact.
  • Consult the MSDS for more specific product and safety information.
  • Clean up with water. Immersing in a tank of water is effective for most applications. A heated water bath is more effective. A water bath heated above 104 degrees F will also flash off all methylene chloride, leaving no residual methylene chloride in the water bath. The water bath should also be maintained with a pH of 8-10. As the pH of the water bath will decrease with extended use, adjusting the pH with soda ash to the 8-10 level is recommended. The pH can be checked with pH strips, available from Benco Sales or from any pool & spa supply store.

 

BEST PRACTICES

  • In most cases, aluminum parts are cleaned sufficiently for re-coating. Steel parts may flash rust after stripping, and a rust inhibitor like Benco #G21 can be applied to prevent flash rusting. The rust inhibitor is easily removed with soap and water prior to re-coating.
  • #B17 is best used in a well-ventilated isolated area in an HDPE tank with a cover. The cover can be either HDPE or plywood. It is acceptable for the stripping tank to be located outside if no sunlight can reach the tank and if temperatures do not exceed 104 degrees F. Since #B17 contains methylene chloride, it should not be used in any area where contact with a gas flame or electric heating element can occur. While non-flammable, contact with gas flames or electric heating elements can break apart methylene chloride into chlorine and phosgene fumes that are hazardous and can corrode heating systems. The best heating system for the stripping area is infrared heating where the element temperature is less than 1000 degrees F. Infrared heat is widely available and is very efficient because it heats the individual rather than air. 
  • Regulations require that the stripping tank be placed in an area with secondary containment that is capable of containing the contents of the stripping tank in case of failure of the tank. A concrete pad with a concrete berm is an acceptable secondary containment. For tanks smaller than 42” X 42”, placing the tank inside the bottom half of an HDPE tote is an effective means of secondary containment.
  • #B17 will rapidly and possibly irreversibly burn on skin contact, so it is essential that proper safety equipment be used in all facets of handling #B17. Essential safety equipment includes:
  • Ventilation: Controlling airborne concentrations below the OSHA TLV exposure guideline is recommended. OSHA TWA is 25ppm. OSHA STEL is 125 ppm for 15 minutes. OSHA Action level is 12.5 ppm. Use only with adequate ventilation. Local exhaust ventilation is necessary for most applications. Lethal concentrations may exist in areas with poor ventilation.
  • Respiratory Protection: Atmospheric levels should be maintained below the exposure guideline. If this level is exceeded, use an approved continuous flow air
  • Skin Protection: Wear chemical resistant rubber gloves, apron, boots, and plastic arm sleeves. Appropriate chemical resistant gloves are butyl rubber or chlorinated treated natural rubber (such as electrical lineman’s) gloves.
  • Eye Protection: Use safety glasses. Where contact is likely, use chemical splash goggles and a safety visor.
