The VINNAPAS EF 3107 from Wacker Chemie AG sits in a plain white sack, but the powder inside quietly decides how your tile adhesive feels under the trowel and how the bathroom wall looks ten years later.
What VINNAPAS EF 3107 is made for
VINNAPAS EF 3107 is a dispersible polymer powder based on vinyl acetate-ethylene, designed mainly for cement-based tile adhesives and repair mortars. It redisperses in water, forming a flexible polymer film in the hardened material.
Product manager Markus Huber at Wacker explains in technical notes that EF 3107 targets standard wall and floor tile adhesives where a balance of adhesion strength, flexibility and workability is more important than chasing laboratory record values.
How it changes mortars in practice
On site, a bag of dry-mix mortar with VINNAPAS EF 3107 smells faintly of cement and chalk when opened, but once water is added, the mixture becomes smoother and more creamy under the steel trowel instead of dragging.
The polymer content improves tensile adhesion strength to typical ceramic tiles and helps mortars bridge hairline movements in substrates, reducing the risk of cracks or delamination in everyday use.
Background on Wacker Chemie shares
VINNAPAS EF 3107 is part of Wacker Chemie’s polymers segment, which supplies countless dry-mix producers and underpins the long-term earnings story behind the Wacker Chemie shares.
Key technical properties
According to the official technical data sheet, VINNAPAS EF 3107 has a glass transition temperature of around +10 °C, which positions it in the middle ground between very rigid and very soft polymer grades. This supports flexibility without turning mortars rubbery.
The powder has a residual moisture of max. 2 percent and bulk density around 500 g/L, which dry-mix producers consider when setting dosing and storage conditions. Wacker recommends storing sealed bags below 30 °C and protecting them from humidity.
Where the longseller fits in the portfolio
EF 3107 is part of a broader VINNAPAS portfolio that spans higher-flex grades for demanding substrates and façade insulation, as well as more rigid products for standard renders. In Wacker’s product finder, EF 3107 appears as a workhorse option for tile adhesives.
The polymers business sits within Wacker’s Construction Chemicals activities, alongside dispersions and other additives that dry-mix formulators combine to tune open time, slip resistance and water retention in mortars.
Who uses it and how it feels
A contractor mixing a wall tile adhesive with EF 3107 can feel a smoother glide as the adhesive combs out, with ribs that stay stable instead of collapsing too quickly when tiles are pressed in. That tactile feedback matters over a long day on site.
Customers in Europe and Asia typically get VINNAPAS EF 3107 through regional building material suppliers who buy polymer powders in bulk and repackage them into branded dry-mix systems, making the polymer an invisible but vital ingredient.
Environmental and regulatory notes
Wacker highlights in its documentation that VINNAPAS EF 3107 complies with key EU chemicals regulations and is designed for low emissions in indoor applications, supporting modern building codes on volatile organic compounds.
The powder itself is not classified as hazardous for normal handling, but safety data sheets still advise avoiding dust formation and wearing appropriate personal protection when emptying bags into mixers.
Context and share reference
Overall, VINNAPAS EF 3107 shows how Wacker Chemie turns polymer chemistry into a quiet backbone of construction materials, far from the spotlight but present in countless tiled bathrooms and floors worldwide.
Wacker Chemie shares (ISIN DE000WCH8881) trade on Xetra, with the price influenced by demand for long-running polymer products such as VINNAPAS EF 3107.
