Additives for Pavement Sealers

Improve the performance characteristics of sealers with premium polymer additives or modifiers.
Additives allow adjustments to mix designs that facilitate various applications from high-sand loading to decreased curing times. However, not all additives are the same. Each has a unique blend of polymers to affect adhesion, cohesion, and viscosity in different ways and to different degrees. It is important to carefully choose the appropriate additive to work with the unique situation at hand. For assistance in selecting, consult the comparison chart.
