Benco Sales is the exclusive manufacturer of B17 stripper, the fastest and safest way to remove powder coat and OEM finishes from aluminum and steel wheels
Benco B17 Industrial Coatings Remover is a liquid, non-flammable remover widely used to remove the most 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, electro-coat 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 and 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.
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. Typical strip time for most powder coating is 5-15 minutes for complete delamination and removal of the coating. Do not agitate or aerate the strip tank as it will encourage evaporation of chemicals in the blend. The delaminated coatings are easily removed from the stripping tank, and when totally dried will not contain residue of the stripper. It is not necessary to remove the stripped coating from the tank, the stripped coatings will not affect stripping effectiveness of B17. The best time to remove stripped coatings is when they are affecting operation. B17 retains stripping effectiveness better than any other product available and will continue to perform until almost all product is used up by either carry-out or evaporation. B17 has the added benefit of being effective 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, and B17 strips in less than 10% of the time required for blast stripping without damage of the substrate caused by blasting.
B17 is most effective and intended to be used by submerging the item into B17 liquid. B17 is used at full strength and not diluted. The best receptacle to store B17 for use is a container made of HDPE (High-Density Polyethylene), a 12 gauge steel or heavier, or of stainless steel. Do not store in aluminum and the only plastic is HDPE as B17 will melt other plastics. It is recommended that you cover your B17 when not in use. It 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 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. Please use B14 for those applications.
B17 is best used in a well-ventilated isolated area in an HDPE tank or heavy gauge steel tank with a cover. 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 item rather than the air.
