Indoor air quality is becoming a competitive factor for furniture and building material makers. Adhesives are a small but critical part of the equation.
What is VOC?
Volatile organic compounds (VOC) are organic chemicals that evaporate easily at room temperature. Solvents in solvent-based adhesives, such as toluene, acetone and ethyl acetate, are the main sources. High VOC raises concerns for worker health, fire risk and end-user exposure.
Formaldehyde
Some reactive dispersions and especially amino-resin glues can release formaldehyde. Furniture and panel buyers ask for low-emission classes such as E1, E0 and CARB.
Isocyanates
PUR hot melts and PU systems contain isocyanates. The cured product poses no risk, but application needs ventilation and protective equipment. Low-monomer (MR) PUR and isocyanate-free POR or MS polymers reduce the risk.
Low-emission alternatives
| Need | Low-emission solution |
|---|---|
| Instead of solvent contact adhesive | Water-based PU dispersion or PSA hot melt |
| Instead of solvent spray | Spray hot melt |
| Instead of classic PUR | Low-monomer PUR or POR |
| Instead of formaldehyde glue | PVAc or 1C PU prepolymer |
| Instead of PU foam/sealant | MS polymer |
Other dimensions of sustainability
- Bio-based raw materials: lower carbon footprint.
- Lower application temperature: energy savings.
- Lower consumption: less material for the same performance.
- Recycling compatibility: formulations that don't hinder packaging recovery.
