DESCRIPTION/WORK STATEMENT/SPECIFICATION

FOR

De-Rusting Compound Contract

1.0 Scope:

This contract establishes the use of an alkaline chemical to: (1) primarily remove rust on ferrous and stainless materials and (2) be a first step in the cleaning process. This is for the turbine engine shop and for the plating lines in Building 114. This process is an immersion process that uses house compressed air for agitation and may cause the need for a de-foamant for foam control in the vat. The vat is heated with steam heat and can reach temperatures in excess of 200˚F for extended periods of time. This requirement is for one year with the potential for an annual renewal for up to four additional years.

2.0 Background:

The material is used in three vats on depot totaling 2000 gallons for the removal of rust from ferrous and stainless products as well as being a first step in a cleaning process and carbon removal process. The material is used at 20-40% BV and heated to 180-200˚F. Parts are submerged into the solution for 1-4 hours depending on the amount of rust to be removed. The solution is dumped once it becomes ineffective. This is done every 2-6 months with the current material.

3.0 Contractor Requirements:

3.1 The contractor shall provide a material that is alkaline in nature and will have a minimum of the following ingredients:

Sodium hydroxide: 30%.

Potassium Hydroxide: 5%.

Gluconate family of chemicals: 25%.

3.2 Material cannot be corrosive to ferrous materials.

3.3 Material must be provided in 55 gallon drums.

3.4 Contractor must provide the following documents:

3.4.A Universal Safety Data Sheet 3.4.B Full formula disclosure 3.4.C Technical Data Sheet with operating parameters and titration procedure.

3.5.D Provide a one gallon sample, if requested, from ANAD within 10 days of the formal request for a sample

3.5 Material cannot have any component listed in the ANAD RED BOOK for prohibited items (See list below).

3.6 Material must be a single component product (all in one drum).

REVISED 2/6/2020

3.7 Material must not have any SARA 313 Reportable agents or Hazardous Air Pollutants (HAPs)

3.8 Material must not have any component that is listed as a US federal government recognized Carcinogen.

3.9 Contractor must be able to supply material within 25 calendar day from time of order.

3.10 Contractor must be capable of 200 drums per year in order increments of 20 drums.

3.11 Testing Requirement:

3.11.A foam generation- no foam with the introduction of compressed air 3.11.B Rust removal evaluation of fresh solution by manufacturer's recommendation concentration at 180F 3.11.C rust removal evaluation of same solution with 10% oil and 5% of 50Be Sulfuric acid added at 180F 3.11.D Cleaning effectiveness testing after extended heating at 200+F
