Wetting and dispersing agent and tinting strength enhancer for waterborne paints.
Benefits of Genapol PN 30 In waterborne coatings, in particular in emulsion paints dispersing agents are added to disperse inorganic pigments like titanium dioxide and „extenders“ like calcium carbonate, talc, China clay, and others.
These dispersing agents are suitable for inorganic pigments but don’t improve the compatibility of organic pigments with the binder system.
Clariant’s Genapol PN 30 is a wetting and dispersing agent for organic pigments and carbon blacks and improves the compatibility of binders in waterborne paints with organic pigments.
Genapol PN 30 offers an increased tinting strength and prevents rub out at dosages of 2 - 5 g/kg of paint.
Particularly organic blue, green and purple pigments and carbon blacks show rub out and reduced tinting strength due to uncontrolled flocculation during the drying of the paint film.
Genapol PN 30 prevents the flocculation of these organic pigments. Rub out does no longer occur and a maximum tinting strength is offered.
Genapol PN 30 additionally reduces the foam build up during the paint manufacture.
Genapol PN 30 releases entrapped air and helps to reduce and save foam control agents in the paint formulation.
• Wetting agent for pigments and fillers in the mill base of waterborne paints
• Tinting strength enhancer for organic pigments
• No hazardous labeling required according to CLP/GHS
• Very low VOC
Principle of performance
Genapol PN 30 improves the compatibility of organic pigments with emulsion binders and overcomes rub out.
Bridging of the pigments with the binders prevents fl occulation during drying of the paint film.
The pigments don’t float or settle but are kept well dispersed in the polymer matrix.
Thus a maximum yield of the tinting strength is obtained .
How to select the right wetting agent/compatibilizer for a tinted coating system
Wetting agents/compatibilizers are added to waterborne and solvent-borne coatings to increase the tinting strength and to improve the compatibility with pigments in order to reduce rub-out effects.
At the same time, the additives might have an influence on other coating attributes such as storage stability, gloss, scrub resistance and foaming behavior.
Tinted paints are highly complex systems.
It can be a technical challenge for the paint formulator to select the right additive to develop a stable, high performing coating formulation, especially when considering that the product’s sustainability aspects, such as low VOC / SVOC or ecolabel suitability, need to be taken into account.
The industry can choose from a variety of additive chemistries.
As a key supplier to paint formulators, Clariant understands that it is important to a paint formulator to identify in a short time the most appropriate product which solves formulation problems with respect to incompatibility.
Clariant has therefore evaluated its range of wetting agents/compatibilizers for waterborne emulsion paints (high PVC), waterborne acrylic lacquers (low PVC) and solvent-borne alkyd lacquers (low PVC) according to the set of parameters listed below.
Our objective is to deliver our customers the best application solution for a longlasting and sustainable business.
