PRIMAL™ AC-412 Containing the AVANSE™ Technology
Description
PRIMAL AC-412 is a versatile pure acrylic polymer for interior and exterior paints.
The product is based on Rohm and Haas unique AVANSE technology. Through the interaction of the binder with the
pigments and extenders, a more uniform distribution of the different particles in the paint is achieved leading to
superior coatings performance, especially in opacity, scrub and stain resistance.
PRIMAL AC-412 has been designed for the formulation of environmentally friendly, low odour, interior wall paints.
It has exceptional pigment binding capacity which permits formulation of flat wall paints at high pigment volume
concentration while maintaining good scrub resistance. Thus PRIMAL AC-412 can be formulated more economically
in solvent-free flat paints compared to competitive technologies.
Paints based on PRIMAL AC-412 exhibit excellent colour acceptance (rub test) thanks to its superior pigment
dispersion. This further distinguishes this binder from other solvent-free products and allows the formulation of
superior quality coatings.
In addition, PRIMAL AC-412 allows the manufacture of interior sheen paints with very good water and stain
resistance.
PRIMAL AC-412 is very well suited for exterior applications (masonry primer and top coat) due to its pure acrylic
composition combined with its strong association with minerals. According to our exposure monitoring, coatings
based on PRIMAL AC-412 exhibit excellent efflorescence resistance.
Additionally, PRIMAL AC-412 demonstrates very good compatibility with siloxane and silicate paints.
PRIMAL AC-412 can also be used as low build stains on wood which makes this binder very versatile.

Formulation Guidelines
The new Rohm and Haas AVANSE technology allows wide formulation latitude. For example, the high binding
capacity of PRIMAL AC-412 is suitable for interior and exterior paint formulations.
Below are some guidelines to help formulators:
Dispersants
Polyacid dispersants such as OROTAN™ N-4045 were found to be the most appropriate for a good pigment
dispersion and a good paint stability. This is true whatever the type of thickeners (Cellulosics, HASE, HEUR).
Combining OROTAN N-4045 with a polyphosphate such as Calgon™ 322N or KTPP (potassium tripolyphosphate) or
a phosphate soap such as Rhodafac™ RS-410 was found to be the best dispersant option for getting optimal
stability with PRIMAL AC-412 based paints. Other more versatile dispersants like OROTAN 731A-ER can also be
successfully used.
Defoamers
BYK™-028 or Tego™ Foamex 1495 were our defoamers of choice for these solvent-free paints. Others like BYK-033
or BYK-035 have also been used successfully.
Rheology Modifiers and Thickeners
PRIMAL AC-412 can be used with the various types of thickeners or rheology modifiers. Since this binder creates a
network via association with mineral particles, it is recommended to lower the level of thickeners, be they
cellulosic, HASE or HEUR. The network created between the binder and the mineral particles depends obviously on
the formulation (type and level of extenders, level of binder, level of thickeners).
All Rohm and Haas ACRYSOL™ HEUR, HASE and ASE can be used with PRIMAL AC-412.
When (re)formulating with PRIMAL AC-412, it is important to determine the appropriate thickener level required for
optimal rheology and paint stability. Formulators are advised to start with a lower level of thickener (especially
lower HEC level), let the paint stabilize overnight, and then adjust the final viscosity. The total thickener level thus
determined can then be adopted in the newly developed formulation based on PRIMAL AC-412.
Coalescents
PRIMAL AC-412 allows film formation without the use of coalescing agent. However, especially for exterior paints,
addition of 3% Texanol on polymer solids can be recommended to ensure film formation even when the exterior
coating is applied under cold and humid weather conditions.
Adjustment of pH
PRIMAL AC-412 is not really sensitive to pH within the range of 7 to 12. It is a very mechanically shear stable
binder whatever the pH. Like with other binders, the pH needs to be adapted to the thickener type used, higher
than 8.5 with ASE or HASE, more neutral with HEUR thickeners.
Extenders and Opaque Polymer
Any common extender can be used with PRIMAL AC-412. Due to the AVANSE technology built in this binder, more
or less strong interaction with the mineral particles can be observed. The nature of the extender, its particle size
and its level can play a role in the interaction and could lead to over-thickening issues. These can be overcome as
previously mentioned by reducing the thickener level in the formulation.
The use of Rohm and Haas organic opacifier ROPAQUE™ Ultra E is always recommended, not only for formulation
cost savings, but also for improved scrub, hiding and dirt pick up resistance.
Titanium Dioxide
Standard titanium dioxide can be used to formulate with PRIMAL AC-412. In our studies, it was seen that a
stronger interaction with some titanium dioxide (usually the ones without silica or zirconium treatment) could lead
to some viscosity build that can be overcome through lower thickener level.
Biocides
PRIMAL AC-412 latex is preserved with a combination of CMI/MIT (5-Chloro-2-methyl-4-isothiazolin-3-one/2Methyl-4-isothiazolin-3-one) and BIT (1,2-Benzisothiazolin-3-one).
Although standard in-can preservatives could be used by the formulators, it is always recommended to test
compatibility and efficacy in small scale quantities. In-can preservatives such as ROCIMA™ 562 can be used.
If PRIMAL AC-412 is used for exterior application or in wet rooms, it is recommended to use a film preservative.
Our biocide experts recommend the use of ROCIMA 350.

Storage and Handling
Most emulsions from Rohm and Haas have excellent storage stability, so agitation is not needed unless the
products are held static for six weeks or more, which may occur in an extended shutdown. Though not absolutely
necessary, intermittent agitation may be used when the tank is heated to hold the temperature constant, but take
care to avoid excessive foam formation. It is highly desirable that the air space over the emulsion in the tank is
humidified to limit skin formation. A regular injection of steam can efficiently maintain a water saturated or humid
condition. A coarse filter (400 – 800 µm) positioned in the transfer line is also recommended to remove any skin or
grit.
When tanks are located at sites (inside or outside), in which freezing temperatures may exist continuously for 12
hours, insulation and heating must be provided to prevent freezing of the emulsion. As a general rule, emulsions
should always be stored at temperatures above 5°C and below 30°C. Most polymer emulsions cannot tolerate
repeated freezing and thawing. Primarily, we recommend vertical tanks constructed from thin walled, reinforced
stainless steel.
