Polyether-based silane-terminated polymer
Featured Product from Wacker Chemical Corp.
GENIOSIL® WP1
Waterproofing, silane-modified polymers
GENIOSIL® WP1 is a polyether-based silane-terminated polymer suitable as
binder in moisture curing formulations. It is a clear liquid with a slight but characteristic odor and differs to conventional silylated polymers due to its high reactivity. This is a direct consequence of the structural proximity of the nitrogen atom to the silicon atom in the dimethoxy(methyl)silyl-methylcarbamate group (alpha-effect). It hydrolyzes in the presence of moisture to finally form a stable siloxane network initiated by mild catalysis as opposed to heavy metal ions.

Construction Sealants
Waterproofing
GENIOSIL® WP
New Generation of Liquid Waterproofing Coatings
Waterproofing is a wide-ranging topic for the construction sector: the diversity of applications from basement to roof is matched by that of the products. Waterproofing products processed in liquid form are becoming increasingly important and have established themselves securely on the market. Our innovative GENIOSIL® WP binders are setting a trend here.
Based on WACKER’s α-technology, these hybrid polymers are the key to innovative waterproofing products, whose properties are comparable to those of polyurethane-based liquid waterproofing coatings. Thanks to its particularly low viscosity, GENIOSIL® WP is easy to formulate – without the addition of solvents, plasticizers or tin catalysts.
The one-component end products do not require classification as hazardous substances and adhere to most substrates without pretreatment. They can be applied by roller, brush or airless sprayer – so craftsmen can work as normal. Due to their moisture-curing properties, they can be processed in all kinds of weather – even on cold, wet days and on damp substrates.
Curing results in a tack-free waterproofing membrane that is rainproof in no time and features good mechanical strength and excellent resistance to chemicals. Furthermore, it bridges cracks and is watertight, yet permits diffusion.
Thanks to their unique property profile, the hybrid waterproofing products can be used in a variety of applications, e.g.:
- Waterproofing for balconies, patios and flat roofs
- Horizontal under-tile waterproofing
- Moisture barrier under floor screeds
- Horizontal waterproofing coating to provide resistance to internally or externally pressing water
- Sealants for horizontal expansion and movement joints
