Asphaltic waterproof coatings

Polymers and additives for asphaltic waterproofing formulations

Polymer-modified asphaltic waterproof coatings are bitumen-based fluid-applied coatings often for below-grade applications. Asphalt has very good water resistive properties, however, lacks strength at ambient temperature and flexibility at lower temperatures. Formulations using polymer-modified asphaltic emulsions see major improvements in coating performance.

BASF’s portfolio offers depth and breadth of technological knowledge in raw materials for traditional polymer-modified asphaltic waterproofing coatings including styrene butadiene latex polymers and formulation additives to optimize performance.
