Glycolic acid 70% for Concrete removal Introduction

Glycolic acid 70% property:

Product name: Glycolic acidhttp://www.chinaglycolicacid.com/wp-content/uploads/2016/01/79-14-1-1.gif

Molecular formula: C2H4O3

Risk category: UN 3265 8/PG 3

Product property:Colorless to light yellow liquid

Glycolic acid 70% function:Glycolic Acid is significantly less corrosive than mineral acids such as HCl. The results are that Glycolic Acid is preferable to use on many metals and surfaces including stainless steel, aluminum, painted surfaces, and most plastics.

Why we use glycolic acid 70% in concrete removal field? Also called Key Attributes

(Used fields: Clean and maintain your tools, equipment, and vehicles with Glycolic Acid based concrete remover formulations.)

1> Efficient at penetrating and loosening concrete.

2> Highly effective calcium complexing agent.

3>Low to no corrosion on most metals and coatings.

4>significantly lower corrosion than hydrochloric acidbased removers.

5> Active ingredient is readily biodegradable.

6>Glycolic Acid is found in natural products, such as fruits and vegetables.

Glycolic acid 70% Application:Glycolic Acid’s high water solubility and small molecular size allow it to penetrate deep inside concrete residues and reactfrom within. Because of its less corrosive nature Glycolic Acid can be used on most surfaces and equipment without concerns for etching and damage. In addition, readily biodegradable

Glycolic Acid is easier to dispose of than other cleaning agents such as phosphoric acid or HCl.

Glycolic acid 70% Corrosivity:Solutions at 10% (100% basis) concentrations of Glycolic Acid, phosphoric acid and HCl were tested for corrosion on 1018 carbon steel, 1100 aluminum, 304, and 316 stainless steel.The tests were performed, in triplicate, at 23°C (73°F) for 48 hours with no agitation. The results are the average of the percent weight loss.

Glycolic acid 70% Instructions:

1>Concentrate

1.1Dilute 1:4 with tap water for use.

1.2 Spray onto surface needing concrete removal.

1.3 Wait at least 30 minutes (allowing to react overnight or between shifts is acceptable).

1.4Powerwash equipment and parts to remove residual concrete

1.5 Extremely heavy residuals may require 2 treatments.

1.6 Wear appropriate personal protection equipment.

1.7 As with all acids it should not be sprayed on hot surfaces.

2>Ready-To-Use

2.1 Spray onto surface needing concrete removal.

2.2 Wait at least 30 minutes (allowing to react overnight or between shifts is acceptable).

2.3 Powerwash equipment and parts to remove residual concrete.

Extremely heavy residuals may require 2 treatments.
Wear appropriate personal protection equipment.
As with all acids it should not be sprayed on hot surfaces.
