Overview

Public consultation on alternatives

Reference: AFA062-01

Applicant:   

Cytec Engineered Materials GmbH in its legal capacity as Only Representative of Cytec Industries Inc (StC)
Indestructible Paint Ltd (StC)
PPG Industries (UK) Ltd (StC, PHD)
Wesco Aircraft EMEA Ltd (StC)

Application type: Review report

Substance name:

• Strontium chromate (StC)
  • EC Number: 232-142-6
  • CAS Number: 7789-06-2
• Potassium hydroxyoctaoxodizincate dichromate (PHD)
  • EC Number: 234-329-8
  • CAS Number: 11103-86-9

Proposed use: Use of primer products other than wash or bonding primers containing strontium chromate and/or potassium hydroxyoctaoxodizincate dichromate in aerospace and defence industry and its supply chains

Broad information on use applied for (conditions of use and function):

The proposed use covers primer products other than wash or bonding primers containing strontium chromate and/or potassium hydroxyoctaoxodizincate dichromate in aerospace and defence industries (comprising of the civil aviation, defence/security, and space industries, along with aeroderivative products). Primer products other than wash or bonding primers are basic primers, structural primers, fuel tank primer, and aluminised primers; where the following key functions are required: Corrosion resistance (including active corrosion inhibition); and Adhesion promotion. It is currently a critical and irreplaceable role in ensuring components meet product performance, reliability and safety standards.

The applicants have identified a shortlist of potentially suitable alternatives. Due to the complexity of design challenges, performance requirements, safety requirements and regulatory controls that must be tested for each listed alternative, and the need for industrial implementation in the whole supply chain, the applicants are seeking a review period of 12 years.

This “applied for use” involves the continued use of strontium chromate across approximately 130 sites across Great Britain (GB).

List of descriptors:

• Sector of end use (SU): 0: Other: Aerospace and defence industry and its supply chains
• Environmental release category (ERC): 5
• Process category (PROC): 0, 5, 7, 8b, 9, 10, 21, 24, 28.
• Product category (PC): 9a

• Technical Function: "Other: Corrosion resistance (including active corrosion inhibition); and Adhesion promotion"

Annual tonnage used:  

• <51.22 tonnes/year - StC
• <2.38 tonnes/year – PHD

Review period requested: 12 years
