New Product: SILIPELL SP2 – Admixture for precast Concrete

In 2016, Tech‑Dry launched Silipell SP2, a new generation admixture for long‑term concrete protection. Silipell SP2 is a silicone‑based emulsion designed for precast and high‑slump concrete. When added during production, it penetrates the concrete matrix and blocks water absorption. This keeps surfaces cleaner for longer and prevents efflorescence, mould, corrosion, and discolouration.

Silipell SP2 builds on the success of Emulsion KR2, another major Tech‑Dry innovation. Both products bond permanently within the concrete. They do not wash out or degrade over time. This sets them apart from common admixtures like stearates and oleates, which are biodegradable and only offer short‑term protection. Silipell SP2 provides durable, long‑lasting performance because it becomes part of the concrete itself.

By reducing water permeability, Silipell SP2 significantly improves durability. The concrete stays stronger and more stable, even in harsh weather. Maintenance needs drop, and refurbishment is often unnecessary. Manufacturers gain a cleaner, more reliable product without changing their production process.

Silipell SP2 suits a wide range of applications. It works in slabs, blocks, pavers, precast elements, and insitu concrete. Because the admixture sits within the material, not on the surface, it protects from the inside out. It also leaves no oily residue and integrates easily into existing production workflows.

Silipell SP2 offers a practical, permanent solution for moisture‑related problems in modern concrete construction. It extends service life, reduces maintenance, and improves overall performance. For full product details, visit the Silipell SP2 product page.
