SYNTECH POLIUREA SPRAY - N

100% pure polyurea for waterproofing in general not suitable for driveways

Code: SYN.0304

Components: 2

Appearance: Liquid

SYNTECH POLIUREA SPRAY - N is a 100% pure polyurea of the aromatic type. It does not contain VOC and can only be applied by spraying using suitable bimixer machines which vaporise the material when hot. It is characterized by a high degree of elongation. SYNTECH POLIUREA SPRAY - N is a coating elastomer obtained from the reaction of an aromatic type isocyanate with an amine. Both materials are extremely fluid and with low viscosity and have the property of reacting very quickly.

Use fields

SYNTECH POLIUREA SPRAY - N is generally used as elastic waterproofing and/or as a protective coating for concrete surfaces for water containment tanks, primary containment, flooring, purification plants, EPS coating, coating and protection of sheet metal, roofs, Eternit roofs, balconies and canopies in wood, tanks and pools.

Preparation of supports

All surfaces must be free of contaminants, with humidity not exceeding 3%; the substrate temperature must be at least 3°C above the dew point. The support must offer a mechanical grip on a solid and non-yielding substrate. For this reason, where necessary, we recommend a preparation carried out with shot-peening, bush-hammering, smoothing or hydro-washing. If necessary, consult Azichem technical staff for a correct evaluation. It is recommended to use a primer from the SYNTECH POLIUREA PRIMER range and always contact Azichem technical personnel for clarifications on the most suitable type to use.

Use method

Pure polyurea SYNTECH POLIUREA SPRAY - N requires a bimixer system capable of producing pressure above 180 bar and temperatures above 65°C. Contact Azichem technical staff for clarification on the best type of gun to use and details of the system air.
