DOWSIL™ IE 6683 Water Repellent

What is DOWSIL™ IE 6683 Water Repellent?

A silane/siloxane emulsion blend, dilutable in water to formulate a less than 200 g/l VOC water repellent. (Low VOC)

Imparting water repellency to porous construction materials such as cementitious materials (mortar and render/stucco), bricks and stones or wood

A water based silane-siloxane emulsion which can be used as supplied or diluted in water to formulate water repellent products
Can be diluted with water
No added Si-H based polymer
Solvent-less and releases little Volatile Organic Content (VOC) upon reaction
Can be applied by vacuum impregnation or surface treatment (brushing/ rolling/ dipping) for the surface treatment of wood
Small molecular structure allows silanes to impregnate the substrate
Silanes react chemically and bond with the substrate which produces durable hydrophobic treatment
Construction materials post treated with DOWSIL™ IE 6683 Water Repellent Emulsion are more resistant against capillary absorption of water
Dilutions of DOWSIL IE 6683 Water Repellent Emulsion are effective as water repellent at weight % of active ingredients as low as 4%
Impregnation of wood with DOWSIL IE 6683 Water Repellent Emulsion does not change surface appearance of impregnated substrates
