Germany-based Wacker Chemie has launched the flexible dispersible polymer powder Vinnapas 4240 N at the Paint Istanbul show last week.
The product offers an exceptionally good balance between flexibility and tensile adhesive strength, the company said.
The powder, which is based on vinyl acetate-ethylene (VAE), is extremely well suited to various wall applications such as adhesive and embedding mortar in external thermal insulation composite systems or finishing plasters, it said.
Wacker also showcased Primis SAF 9000/9001, Silres BS 710, and Silres BS 6920 from its portfolio for various easy-to-clean applications.
Wacker is expanding its portfolio of dispersible polymer powders to include Vinnapas 4240 N. The high proportion of ethylene in the polymer chain means that Vinnapas 4240 N has a low glass transition temperature. It, therefore, displays good crack-bridging properties and improves the flexibility of mineral mortars, which provides excellent compensation for tensions that occur as a result of temperature fluctuations, weathering, shrinkage of construction materials, or vibrations.
The flexible dispersible polymer powder also features particularly good resistance towards severe impacts, which plays a major role for embedding mortars in external thermal insulation composite systems as well as finishing plasters.
In addition, Vinnapas 4240 N enhances the cohesion of the end product, thereby improving adhesion to inorganic and organic surfaces. Consequently, an extremely strong adhesive bond can be formed between EPS panels and masonry, for example, in adhesive and embedding mortars in external thermal insulation composite systems.
In thick-layer finishing plasters such as thermal insulation plasters, the greater cohesion also generates improved mechanical properties.
Recently Wacker Chemie AG Group announced that its sales reached €4.92 billion ($6.092 billion) in 2017, up 6% year over year (2016: €4.63 billion).
The company met or surpassed its own projections for all its performance indicators in 2017, it said presenting its annual report.
The group’s net income for the year was €884.8 million (2016: €189.3 million). It included €634.7 million in income from discontinued operations from Q1 2017. This amount comprised both the gain associated with the deconsolidation of Siltronic as a Wacker Group segment and Siltronic’s net income in the first quarter of 2017, the company said.
The Munich-based chemical company announced that the rise was mainly due to higher volumes in chemicals and in polysilicon. As a result, Wacker more than compensated both for negative currency effects due to the euro’s strength against the US dollar and for prices that, on balance, were somewhat lower, it said.
