Water-Based Caulks

VINNAPAS® and VINNOL® vinyl acetate-ethylene (VAE) dispersions are used as core-strength binders for water based and flame retardant caulking applications. WACKER’s state-of-the-art application labs are equipped to perform tests confirming compliance with ASTM C834 and ASTM C920 norms.

VINNAPAS® and VINNOL® Based Sealants and Fire Retardant Caulks

In connecting joints as well as in sealing gaps and cracks, VINNAPAS® and VINNOL® VAE co- and terpolymer dispersions offer numerous advantages, including high filler acceptance and excellent adhesion to many substrates. They are ideal in the formulation of sealants and caulking compounds.

  • Low-Tg grades are an excellent choice when the use of external plasticizers is not desired.
  • Our binders can be used to formulate sealants that meet the requirements of ASTM C834 and C920 norms.
  • We also offer products tailored specifically for applications in which intumescence or flame retardation is essential.
  • Due to their low odor, they are ideal for interior applications.

The results: reduced odor and an advantageous cost-in-use balance.
