Exterior Paints & Coatings
For exterior paints, WACKER offers solutions based on silicone chemistry, organic chemistry or a combination of both.
Our silicone-based water repellents for concrete and masonry provide the most effective protection against water damage by forming an extremely stable, and thus highly durable, three-dimensional silicone-resin network that repels water but is permeable to water vapor.
Our VAE co- and terpolymer dispersions are attractive alternatives to conventional acrylic and styrene-acrylic systems for outdoor applications.
The color stability of exterior paints formulated with a VAE dispersion is far superior to that of paints based on typical styrene acrylics. After 6 weeks of UV exposure, the color of the paint sample containing VINNAPAS® based on VAE (pictured above) matches the original far better than the styrene-acrylic paint sample.
VINNAPAS® co- and terpolymer dispersions allow the formulation of exterior paints with an excellent balance of environmental and performance benefits. They can be used as the sole binder or in blend systems for a variety of exterior applications, such as architectural paints or general wall paints.
Benefits:
- Good water resistance
- Good mechanical strength for high durability
- Protection against efflorescence
- Alkaline hydrolysis resistance
- Low flammability
- Outstanding exterior weathering behavior
- Low solvent demand
- Low levels of formaldehyde
PRIMIS® includes a range of binders, co-binders and highly effective additives for innovative, high-value exterior paints. The outstanding properties of PRIMIS® products enable the development of formulations with unique properties that would hardly be possible otherwise.
Some of the benefits:
- Reduced dirt pick-up
- Excellent color stability
- Reduced emulsifier leaching ("snail trails")
- Immediate protection against rain
SILRES® BS for silicone-modified silicate coatings are nonionic, solvent-free water-dilutable emulsions of a reactive polysiloxane. They are used in undiluted form as water-repellent additives for waterborne architectural coating materials.
Benefits:
- Water-repellent
- Improved ease of processing and storage stability
- High vapor permeability
SILRES® BS for silicone resin emulsion paints and plasters (SREP®) in exterior applications are solvent-free, waterborne emulsions based on silicone resins or silicone additives. They have extraordinary processing properties and remain securely and irreversibly anchored to substrates.
Benefits:
- Low water uptake
- Combination of water-repellency and breathability
- Low dirt pick-up
- Very high UV resistance
- Suitable for eco-label-certified coatings
- Support energy-saving facades (CO2 reduction)
