Dispersible Polymer Powders

Polymer powders are produced by spray-drying polymer dispersions. In contact with water, the dispersible polymer powder grains disintegrate and release the individual dispersion particles again. The dispersed polymer powder has the same properties as the original dispersion. Polymer powders were first produced in WACKER laboratories in 1957. Today, WACKER is the world market-leader in polymer powders.

Dispersible Polymer Powder Production Process

PVAc increases the adhesion of mortars. When the dry-mix mortar is mixed with water on the job-site, the polymer powder redisperses and forms polymer bridges as shown here.

Polymer powders based on VAE are marketed under the trade names VINNAPAS®, VINNACEL® and ETONIS®.

Main Characteristics:

VAE polymer powders combine the adhesion of vinyl acetate with the flexibility of ethylene. This leads to various ecological and economic benefits without compromising performance.

Main Benefits:

  • Excellent Cohesion
  • Very good adhesion to critical substrates such as wood, plastics or polystyrene
  • Flexibility can be engineered without the need to add plasticizers
  • Good low-temperature film forming without additional coalescing agents
  • Glass transition temperatures (Tg) from high to low are possible
  • All modern polymer powders are produced without added APEOs

Main Application Areas:

  • Construction
  • Concrete modification
  • PVAc

Co- and terpolymer powders based on vinyl chloride are marketed under the tradename VINNAPAS®.

Main Characteristics:

VC-based dispersible polymer powders show excellent water resistance.

Main Benefits:

  • High water resistance
  • Excellent open time
  • Excellent tensile adhesion
  • High hydrophobicity

Main Application Areas:

  • Cementitious tile adhesives
  • Cementitious tile grouts
  • Skimcoats

Terpolymers based on VAcE and VEOVA are marketed under the trademark VINNAPAS®. VEOVA and vinyl laurate monomers are marketed under the name VERSA®.

Main Characteristics:

Polymer powders based on VAcE and VEOVA have a very low Tg.

Main Benefits:

  • Very good crack-bridging behavior
  • Excellent tensile adhesion strength
  • Non-slump behavior
