Durasoil®, a synthetic, non-petroleum-based dust suppressant from Soilworks, successfully met all Boeing BSS7432 testing criteria for use around aircraft, confirming its compatibility with sensitive aviation materials and coatings. The product passed critical assessments including the Sandwich Corrosion Test, Acrylic Crazing Test, Paint Softening Test, and Hydrogen Embrittlement Test, demonstrating no corrosive effects, material degradation, or structural compromise. These results validate Durasoil’s effectiveness in high-risk aviation environments where dust control must not interfere with operational safety or equipment integrity.
Ideal for runways, helipads, taxiways, and aprons, Durasoil offers long-lasting dust suppression without water, making it especially suitable for areas requiring strict control of foreign object debris (FOD). Its clear, odorless, and non-corrosive formulation ensures safe use in high-traffic zones while supporting compliance with FAA and aerospace standards. For aviation professionals seeking a durable, eco-safe solution to airborne particulates, Durasoil delivers unmatched performance with proven material compatibility.

Sandwich Corrosion Test: Specimen preparation, testing, and interpretation must be in accordance with ASTM F1110 using the following materials and with the following exceptions:
a. Reagents and materials exception:
(1). Clad 7075-T6 aluminum alloy in accordance with AMS-OO-A-250/13 (AMS 4049 or AMS-QQ-A-250/13 optional) (2024-T3 Alclad specimens are neither required nor optional.)
(2) Bare 7075-T6 aluminum alloy in accordance with AMS-QQ-A-250/12 (AMS 4045 or AMS-Q-A-250/12 optional) anodized in accordance with BAC 5019 or MIL-A-8625, Type I.
(3) Anodize must be sealed. (2024-T3 nonclad specimens are neither required nor optional).
(4) Distilled or deionized water may be used in place of ASTM F1193, Type IV reagent grade water for control specimens.
(5) The filter paper may be Whatman No. 5 or equivalent in place of Whatman GFA glass fiber paper.
b. Procedure exceptions:
(1) The filter paper strips must be 1 by 3 inches and must be placed in the center of the sandwiched specimens.
(2) Each sandwich specimen must be held together with waterproof tape, with no more than 1 piece of tape (maximum width 0.75 inch) on each of two opposite edges.
c. Interpretation of result exceptions:
(1) Leaching or lightening of the chromate sealed anodize coating must not be
cause for rejection.
(2) Deposits or residues from the material being tested that are not products of corrosion of the test panel surface must not be cause for rejection.
(3) Special procedure for evaluation of fire extinguishing foams and liquids. Panels with very light darkening or staining, which have no obvious metal attack or pitting, may be swabbed (cotton-tipped swabs or cotton gauze) with a 0.26 mole/liter sulfuric acid solution and re-examined. If the coloration is substantially removed and there is no evidence of metal attack or pitting, the condition must not be cause for rejection. (The 0.26 mole/liter sulfuric acid solution can be prepared by adding 1.5 cc of concentrated sulfuric acid (SG = 1.84) to 100 cc of distilled or deionized water.
(4) Panels must have a rating of 1 (no more than 5 percent of the surface area must be corroded) or better in accordance with ASTM F 1110. The preferred method of determining the corroded area is by using image analysis. Other means approved by the purchaser may be substituted.
(5) Any corrosion in excess of that shown by the control group must be cause
for rejection.

Acrylic Crazing Test:
The material being tested must not craze, crack, or etch acrylic test specimens when tested in accordance with ASTM F 484 using Type C (stretched acrylic plastic in accordance with MIL-P-25690) stressed to an outer fiber stress of 4500 psi.
PRODUCT: No crazing, cracking, or etching

Paint Softening Test Procedure:
a. Testing must be in accordance with ASTM F502 using the following coating systems.
(1) BMS 10-79, Type II primer applied in accordance with BAC5882 plus BMS 10-60, Type II enamel in accordance with BAC5845.
(2) BMS 10-79, Type Ill primer applied in accordance with BAC5882, plus
BMS 10-100 coating in accordance with BAC5797.
b. Three specimens conforming to Section 7.7.a.(1) and three specimens conforming to Section 7.7.a.(2) must be used for each test condition.
c. The material being tested must not produce a decrease in film hardness greater than two pencils, or any discoloration or staining.
NOTE: Slight darkening of the BMS 10-100 surface is acceptable.
As received: Paint system 1: < 2 pencil hardness change after 24 hour post-exposure dry time. Paint system2: < 2 pencil hardness change after 24 hour post-exposure dry time.
