Waxes and Water-Repellent Additives 

ADIWAX® and CERFOBOL, surface performance and protection for coatings

Wax-based additives play an important role in coating formulations, helping to control surface appearance, improve mechanical resistance and provide water repellency and specific handling properties.

Lamberti offers a range of wax emulsions , solvent dispersions and specialised water-repellent additives for water-based and solvent-based coating systems.

The ADIWAX® portfolio includes synthetic and natural wax technologies designed to modify the appearance, protection and feel of coated surfaces. CERFOBOL  R/75 complements this offering with a solution specifically developed to improve water repellency in architectural coatings.

ADIWAX® – Tailoring Surface Properties

ADIWAX<sup>®</sup> – Tailoring Surface Properties

The ADIWAX® range provides formulators with different wax chemistries and preparation technologies to achieve specific surface characteristics.
Depending on the selected grade and formulation, ADIWAX® additives can deliver benefits across three main areas:

  • Appearance: gloss and matting control, improved orientation of metallic and effect pigments.
  • Protection: scratch and mar resistance, water repellency and reduced surface marking.
  • Surface feel and handling: slip control, soft-touch effects and antiblocking properties.

Solutions for Different Coating Applications

In wood coatings, wax additives contribute to both the aesthetic and functional properties of the finish.

ADIWAX® solutions help achieve uniform matt surfaces, improve scratch and mar resistance and provide a pleasant soft-touch effect. Selected wax dispersions can also enhance the efficiency of silica-based matting agents, supporting consistent surface appearance and formulation stability.

In metal coatings, including direct-to-metal (DTM) systems, wax additives can help improve surface properties such as scratch resistance, slip and water repellency, depending on the formulation.
For coil coatings, selected ADIWAX® grades provide slip and scratch control while maintaining the desired gloss.
In industrial anticorrosive coatings, specialised wax-based additives can also contribute to rheology control, anti-settling and sag resistance, supporting the stability and application properties of highly pigmented formulations.

Wax dispersions can play an important role in controlling the orientation and stability of aluminium and pearlescent pigments.

Selected ADIWAX® DSP grades help improve pigment orientation and reduce settling, supporting a uniform metallic appearance and the desired flip-flop effect.

In leather finishes and foil topcoats, wax additives help modify surface characteristics, providing water repellency and slip control.

Selected ADIWAX® emulsions and dispersions allow formulators to adjust surface behaviour and achieve the desired balance between appearance, protection and handling properties.

In architectural wall paints, wax emulsions can improve surface water repellency, helping to limit water wetting and enhance the protective properties of the coating.

ADIWAX® solutions provide formulators with additional tools to control surface characteristics while maintaining the desired appearance of the finished paint.

CERFOBOL R/75 – Water Repellency for Architectural Coatings

CERFOBOL R/75 – Water Repellency for Architectural Coatings

CERFOBOL R/75 is a water-based hydrophobic additive designed to improve water repellency in architectural paints, decorative coatings and wall primers.
By forming a water-repellent film while maintaining water vapour permeability, CERFOBOL R/75 helps protect coated surfaces against water penetration without compromising their breathability.

Its main benefits include:

  • Short- and long-term water repellency, helping to protect coated surfaces from water absorption.
  • Improved early rain resistance, supporting the performance of freshly applied exterior coatings.
  • Reduced snail track formation, helping to limit visible water-related streaks on façades.
  • Water vapour permeability, allowing the coated substrate to remain breathable.

CERFOBOL  R/75 is suitable for waterborne interior and exterior paints, decorative wall coatings and breathable primers. It provides formulators with a dedicated solution for improving the water-repellent performance of architectural finishes.
