Benefits of technology

The patent aims to provide coating systems, particularly roofing systems, that offer superior performance, durability, and insulation properties. These systems are based on a limited number of components that can be processed effectively and prepared in a cost-effective manner.

Problems solved by technology

The preparation of such multilayered coating systems is very labor-, cost- and time-intensive.
Furthermore, many different components have to be applied resulting in a complex logistic at the building site.

Embodiment Construction

[0007]Light weight aggregate are generally known as low density aggregates, such as vermiculite, perlite, poraver glass beads, hollow glass spheres, natural lightweight aggregate, like pumice, expanded clays or shales, like ridgelite or utelite, sintered pulverised fuel ash.

[0008]Suitable polymers from ethylenically unsaturated monomers are for example those based on one or more monomers from the group comprising vinyl esters of carboxylic acids having from 1 to 15 carbon atoms, methacrylic esters or acrylic esters of carboxylic acids with unbranched or branched alcohols having from 1 to 15 carbon atoms, olefins and dienes, vinylaromatics and vinyl halides.

[0009]Preferred vinyl esters are vinyl acetate, vinyl propionate, vinyl butyrate, vinyl-2-ethylhexanoate, vinyl laurate, 1-methylvinyl acetate, vinyl pivalate and vinyl esters of α-branched monocarboxylic acids having from 9 to 13 carbon atoms, for example VeoVa9R or VeoVa10R (trade names of Shell). Particular preference is given ...

Abstract

The invention provides coating systems comprising a) a base layer, b) middle layer and c) top layer, whereby each of the layers a), b) and c) is based on mineral binder, filler, polymers from one or more ethylenically unsaturated monomers and optional further additives, and whereby the middle layer contains additionally light weight aggregates.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the national phase filing of international patent application No. PCT / EP2011 / 060806, filed 28 Jun. 2011, and claims priority of United Arab Emirates application number 2010 / 724-P, filed 30 Jun. 2010, the entireties of which applications are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to coating systems, particularly roofing systems, comprising three layers on the basis of mineral binders, fillers, polymers as well as processes for the preparation of such coating systems.BACKGROUND OF THE INVENTION[0003]In construction engineering it is very common to prepare coating systems comprising a number of different layers in order to fulfill the requirements for heat and sound insulation as well as protection against rain or snow. Due to the long-term use of buildings and the high costs for their renovation it is of high importance that each constructional unit of buildings satisfies high ...
