Mineral Fibres for Coatings

Mineral fibres support coating reinforcement, making it more resistant to cracking, chipping, and wear caused by external factors. The high aspect ratio (length divided by diameter) of Lapinus mineral fibres further reinforces the application.

Our products Lapinus MS fibres remain stable up to 1.100 °C, while Lapinus CF fibres remain stable up to 700 °C. In intumescent coatings, MS fibres physically reinforce the char, while CF fibres can chemically interact with reactive components to strengthen the char layer. This thermal stability creates an effective heat barrier and reduces structural damage.

Temperature fluctuations and mechanical movements can cause micro-cracks. Stone wool fibres hold the structure, providing controlled flexibility that prevents cracking or deformation. This helps the coating remain smooth, uniform, and durable over time.

Properly dispersed fibres help control the coating’s viscosity, making it easier to apply. They allow thicker layers without sagging or running, ensuring a smooth and uniform finish every time.

Mineral fibres hold pigments and fillers in place, keeping coatings strong, durable, and visually appealing. They are compatible with wetting and dispersing (W&D) agents, which ensures the fibres integrate well into the formulation and that the coating maintains its performance and decorative appearance over time.

Lapinus fibres are made entirely from stone and provide long-lasting reinforcement. The mineral fibres strengthen the coating without changing its composition. This helps the protective and decorative features last longer. By keeping the coating effective over time, they reduce the need for frequent maintenance or re-application, supporting more sustainable and environmentally responsible solutions.
