Mastic waterproof coatings

Polymers and additives for mastic waterproofing formulations

Mastic waterproof coatings are one-component ready-to-use coatings that can be rolled or sprayed onto horizontal and vertical surfaces on various substrates. In above-grade applications, these waterproofing membranes prevent water intrusion into construction elements.

BASF’s portfolio offers depth and breadth of technological knowledge in raw materials for ready-to-use mastic waterproofing coatings including styrene acrylic and styrene butadiene latex polymers as well as formulation additives to optimize performance.

Binders

ACRONAL® 4040Styrene-acrylic copolymer designed for water-based concrete cure and seal coatings to deliver both benefits of a curing agent and sealer in a single coating application.
ACRONAL 4160Styrene-acrylc emulsion polymer ideal for waterproofing coatings on masonry/concrete surfaces. Formulated coatings resists standing water, withstands negative-side hydrostatic pressure, prevents water intrusion.
ACRONAL 5041Multi-purpose styrene acrylic copolymer dispersion for various low-emission applications including waterproofing over various substrates. Fast drying with superior adhesion and good crack bridging properties.

Additives

DISPEX® CX 4320Polymeric dispersing agent for TiO2 and extender pigments. Efficiency and high water resistance.
FOAMSTAR® ST 2420Defoamer for pigment dispersing. Low use level, excellent persistence, good choice for very low VOC systems.
FOAMASTER® MO NXZGeneral purpose, broad spectrum mineral oil defoamer for water-based formulations.
RHEOVIS® AS 1130Highly efficient low-shear viscosity builder. Highly shear thinning for anti-sagging and anti-settling properties.
RHEOVIS PU 1341Excellent high-shear viscosity builder. Imparts excellent flow.
HYDROPALAT® WE 3320Low foaming, non-ionic surfactant. Extender pigment acceptance with improved substrate wetting.
