Protectosil WS 405 A

Aqueous emulsion based on organofunctional silanes for the water repellent impregnation of absorbent, mineral substrates with excellent beading effect.

Protectosil WS 405 A

For most applications a concentration of from 5% (1 part Protectosil® WS 405 A 9 parts of water) to 20% (1 part of Protectosil® WS 405 A 1,5 parts of water) of the active ingredient in demineralized water is recommended. The amount of Protectosil® WS 405 A to be applied and the concentration to be used are highly depending on the absorbance of the substrate and the desired penetration depth. Very absorbent substrates may require up to 1 l/m² of Protectosil® WS 405 A. The substrates to be treated should be dry and clean. Acceptable surface cleaning methods include sandblasting and water blasting. During application outside temperatures and surfaces temperatures should be between 5 °C and 40 °C. Protectosil® WS 405 A should not be applied during strong wind or rain.
