Coatings additives
Our broad range of speciality surfactants continue to contribute to the growth of high-performance waterborne coatings additives that meet the most stringent end application requirements, are safer in use and have an improved environmental profile.
Emulsion technology is core to Croda and we therefore offer a selection of polymeric, polymerisable and non-ionic surfactants that can be used to formulate water-based coatings with enhanced film properties to meet your customer needs.
The speciality surfactants portfolio brings the following benefits:
- VOC elimination, reduction and replacement by water whilst retaining final paint film properties;
- enhanced final paint film properties such as gloss, colour development and improved drying times;
- improved coating properties such as hydrolytic stability and protection against moisture;
- optimised resin content for improved cost efficiency whilst retaining paint performance; and
- improved environmental profile.

Alkyd resin
Waterborne alkyd resin coatings
We offer a range of specialty polymeric surfactants, Maxemul 7000 series, to formulate high performing VOC free waterborne alkyd resins. Our versatile surfactant range is application to short, medium and long oil alkyds. Emulsions typically have solids content up to 55%, low viscosity, excellent shelf life and enhanced dry film properties.
Maxemul 7000 polymeric surfactants bring the following benefits in use:
- Formulation of cost-effective VOC free alkyd resins
- No reformulation of the alkyd required
- Good compatibility with pigments and rheology modifiers

Coatings formulations
Croda offers formulation guidelines and a variety of emulsification processes tailored to your needs:
- Direct-to-Metal coating formulation
- Flat wall paint formulation
- Low VOC High Gloss Trim Paint formulation
Cost and VOC reduction in solvent-borne alkyd based paints
LoVOCoat surfactant will allow you to formulate with water as liquid filler in solvent-based paint formulation and provides formulators these benefits:
- Formulate low VOC high quality alkyd paint
- Cost savings by replacement of solvent with water without impacting performance
- Low VOC alkyd paint with fast drying time
- Minimal impact on hardness, gloss retention and film transparency
- Regional product availability
LoVOCoat range
VOC reduction for solvent based paints
- LoVOCoat Sol 500: 50% w/w concentrate, for pre-emulsions
- LoVOCoat Form 100 / LoVOCoat Stable 100: 20% in D80/water, for direct water incorporation
- LoVOCoat LFM 500: for more polar alkyds (high OHV)
Emulsion polymerisation
Reactive surfactants, MaxemulTM 5000 and 6000 series, are being used in acrylic and vinylic waterborne binders to enhance performance in wall paints,
wood coatings and metal protection, pressure sensitive adhesives and others. Maxemul reactive surfactants for emulsion polymerisation are emulsifiers
that copolymerise with the main monomers during the polymerisation process and remain evenly distributed in the dry film, improving the end use
properties of emulsion polymers.
These products offer the following benefits to the latex and dry film:
- Protection - enhanced scrub resistance, faster drying, increased water, stain and salt spray resistance;
- superior adhesion to the substrate; and
- good appearance - higher gloss and gloss retention; non-whitening in humid conditions.

Why reactive surfactants?
Maxemul reactive surfactants are emulsifiers that copolymerise with the monomers during the polymerisation process and remain evenly distributed in the dry film, dramatically improving performance properties of emulsion polymers.
Maxemul surfactants are grafted onto the surface of polymer particles and thus enhance latex stability properties. The absence of free surfactants in the dry film results in film properties with equivalent performance to solvent-borne resins.
Location of surfactant in the dry film
Superior colloidal stability of the latex and formulated system increases:
- pigment binding;
- shear and freeze/thaw stability; and
- stability even in the presence of high levels of coalescent and alcohols.
Enhanced properties and durability of the dry film:
- Coating protection
- Higher scrub resistance
- Increased water, stain, blocking and salt spray resistance
- Drying speed
- Multi-substrate adhesion
- Ultimate appearance
- Higher gloss and gloss retention
- Non-whitening in humid conditions
Additives
100% bio-based ECO range of surfactants
We offer to the market non-ionic and anionic surfactants, which are used as wetting agents, emulsifiers, co-emulsifiers, stabilisers in emulsion polymerisation and dispersants. We also offer PolyEthylene Glycols (PEGs) and vegetable oils used in many applications.
Discover our ECO range of 100% bio-based surfactants and PEGs. Over 50 products make up the ECO range made by using bio-based ethylene oxide (EO) which we manufacture from biomass ethanol. Coupling the use of bio-based EO with the high proportion of renewable energy used at the manufacturing plant, leads to a significant reduction in carbon footprint for the ECO product range. Formulators can now access 100% renewable surfactants without sacrificing performance to help meet increasingly demanding sustainability targets.
