2.2 Lowering VOC Emissions: Breathing Easier with DMCHA

Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. VOCs are emitted from a wide array of products, ranging from paints and coatings to adhesives and cleaning agents. They contribute to air pollution, smog formation, and can have adverse health effects.

DMCHA can help reduce VOC emissions in several ways:

Water-Based Formulations: DMCHA can be used as a neutralizing agent in water-based formulations, allowing manufacturers to replace traditional solvent-based systems. Water-based systems significantly reduce VOC emissions, making products safer for both the environment and human health.
Reactive Diluents: DMCHA can be incorporated into reactive diluents, which are substances that react with the main components of a formulation, becoming part of the final product. This reduces the amount of volatile substances that are released into the atmosphere.

2.3 Promoting Resource Efficiency: Doing More with Less

DMCHA can contribute to resource efficiency by:

Reducing Waste: By acting as an efficient catalyst, DMCHA helps minimize side reactions and maximize the yield of desired products. This reduces the amount of waste generated during the manufacturing process.
