Moisture in concrete can arise from various sources, including trapped moisture, saturated sub-base soil, groundwater, and poor drainage. It migrates through concrete slabs due to capillary pressure and temperature gradients, potentially causing floor failures like blistering, delamination, and dampness, leading to significant repair costs.
To prevent adhesive failure, it's essential to minimize moisture vapor transmission, which can be achieved with a resin-rich barrier coating. Two-component epoxy coatings are favored for their strong adhesion and low moisture vapor transmission but often require plasticizers for optimal performance.
Evonik has developed new amine curing agent technology that reduces or eliminates the need for plasticizers, resulting in lower emissions while maintaining high curing performance. This webinar will showcase the benefits of this technology, including rapid property development and customizable curing rates, enabling the creation of ultra-thin coatings with effective moisture vapor barrier properties.
