Lapinus for Coatings

High performing mineral fibres for durable and fire protective coatings

Lapinus mineral fibres are used in a wide variety of coatings to improve their mechanical and thermal properties. Our fibres help to make paints more durable by improving mechanical and aging resistance, from architectural decorative paints to industrial coatings. Thanks to their high temperature resistance, our fibres play an important role on fire protection coatings by providing a controlled char formation and improved char strength. Made from 100% stone, our inorganic mineral fibres contribute to a ‘greener’ coatings solution for you.

Our mineral fibres have a L/D ratio up to 100:1 which provides a unique dimensional stability for a stronger coating structure

Stable performance up to 1000°C fire protective coatings using our mineral fibres will buy more time, ensure higher safety and reduce damages in case of fire

Made by 100% of stone, our inorganic mineral fibres are safe for human and environment, contributing a greener product for you

Applications

Fire protective coatings

High performance fire protective coatings

Our mineral fibres are widely used in both hydrocarbon and cellulosic intumescent coatings. In case of fire they can:

- Provide a controlled char formation by reducing slumping and char cracks (also tubular)
- Improve char strength with longer lasting time by providing dimensional stability (mechanical and chemical reinforcement), reducing internal stress

Durable paints

More durable paints with ease of application

Durability and ease of application are two key elements for a high performance paint product, our mineral fibres help to:

- Improve mechanical strength (impact, abrasion, and scratch resistance) and aging resistance (weather and chemical-proof) by providing dimensional stability and reducing internal stress
- Improve method of application by reducing tendency to sag and giving possibility to applying thicker layers
- Improve dry film forming properties by increasing crack resistance and gap bridging

Instructions

Processing

A uniform dispersion of Lapinus’ fibres minimizes their impact on the viscosity of the system and ensures maximum dimensional stability. Dispersing fibres in paints is usually done by using a high speed dissolver with tooth blade. Fibres can be added at any stage during the formulation process as long as there is enough shear available to separate them. Wetting and dispersing agents can be used to optimize dispersion.

Spray ability

A good dispersion of fibres benefits the spray-ability. The short grade of Lapinus CF and Lapinus MS can be spray applied. Middle-long and long grade fibres need a 419 nozzle without the use of filters.

Packing and surface area

Fibres need to be incorporate into the coating system to see the optimal effect. Addition of fibres or exchange fibres with fine or coarse particles can result in differences in performance:

Fibres change the packing due to the their particle size and shape;
Fibres have a very low surface area and change the Pigment Volume Concentration (PVC) and binder ratio.

High temperature behaviour

Lapinus' fibres give an excellent performance at elevated temperatures up to 1100 °C. For intumescent coatings Lapinus MS maintain their shape and gives a physical reinforcement of the char. Lapinus CF reacts with some of the reactive components and gives a chemical reinforcement of the char layer.
