At LCS Laboratory Inc., we are committed to supporting safer construction practices through innovative analytical services. Our latest development addresses a growing concern in the building industry: the formation of Methylenedianiline (MDA) in cured construction foam.

Understanding the Risk: MDI and MDA

Construction foam is widely used as an insulation and sealing material in residential, commercial, and industrial projects. It is typically produced through self-polymerization of Methylene Diphenyl Diisocyanate (MDI) — a reactive compound that hardens to form a durable, lightweight structure.

However, when MDI is exposed to moisture during application or curing, it can react with water to form Methylenedianiline (MDA), a carcinogenic compound. Incompletely cured foam or prolonged exposure to humid environments can increase the likelihood of this dangerous transformation.

MDA is not only harmful to workers during installation — it can also pose long-term risks in finished buildings, especially when disturbed during renovation or demolition.

Our New Testing Method

To address this concern, LCS Laboratory has developed a specialized method for detecting trace levels of MDA in cured construction foam. Based on a modified NIOSH Method 5029, our procedure includes:

  • Extraction of MDA from foam materials
  • Quantitative analysis using High Performance Liquid Chromatography (HPLC) with UV detection

This method is optimized for sensitivity and reliability, even when testing small or aged samples. It is ideal for:

  • Industrial hygienists assessing indoor air quality and material safety
  • Occupational health and safety officers
  • Environmental consultants investigating legacy building materials
  • Construction and remediation companies concerned with hazardous exposures

Why This Matters

MDA is recognized as a probable human carcinogen and should be avoided or minimized in any building environment. By offering this service, LCS Laboratory enables clients to:

  • Confirm the chemical safety of insulation foam
  • Support compliance with occupational exposure regulations
  • Identify sources of chemical contamination in indoor environments
  • Make informed decisions during construction, renovation, or demolition projects
