Heating, Ventilation, Air Conditioning (HVAC)

WACKER introduced vinyl acetate-ethylene (VAE) for caulks and sealants already in the 1980s. Today, WACKER is a technology leader in VAE applications for caulks and sealants. With the global trend towards more environmentally friendly products, there is a need for alternatives to products that are solvent-based. Recent regulations call for lower VOCs, such that low-VOC technologies are rapidly gaining favor. WACKER offers a high-quality, environmentally compatible product portfolio for HVAC applications.
