VELVACOATThe versatile defect preventative alcohol-based coating
ASK Chemicals alcohol-based VELVACOAT coatings come in many refractory formulations suited for the
non-automotive & specialty sectors. Noted for its versatility, VELVACOAT is an ideal coating within multiple
applications & metal types. Engineered speciﬁcally towards the mitigation of particular casting defects (e.g.
burn-in / penetration) VELVACOAT contributes minimum carbon pickup, as well as low mineral oxides. These
characteristics, in addition to others, make VELVACOAT an excellent solution in solving common surface
defects. Multiple applications are acceptable with VELVACOAT coatings: brushing, spraying, ﬂow coatings anddipping.

Benefits• Very fast drying time
• Available in cooler burning formulations• Helps reduce surface defects

Without Coating

Avoiding penetration defects

With Coating

The superior refractoriness of VELVACOAT coatings, for iron castings with high graphite, make it
an exceptional solution for avoiding surface defects, like penetration. Penetration is caused by achemical reaction between the mold and molten metal. Identifying this defect is key. The casting
surface will ultimately appear rough and uneven. Using a proper coating, such as VELVACOAT will
help ensure the integrity of your casting.

CERAMCOTE
The versatile high-performing water-based coating
CERAMCOTE coatings were specificallydesigned for the Lost Foam and Full Mold technologies. A staple

within the industry, CERAMCOTE provides superior performance and consistency to the automotive andnon-automotive markets. Utilizing a special proprietary formulation, ASK Chemicals has optimized the rheological properties of CERAMCOTE (i.e. viscosity and layer thickness). Stable viscosity determines the evennessof the coating layer to prevent casting defects such as metal penetration, burn-on defects, cracks and scabs.
CERAMCOTE offers superior bond strength and ductility. The dried coating can withstand even the most
severe mechanical stress during sand compaction. This coating line is available for a variety of application
methods, predominately dipping.

Benefits• Tailored permeability and insulating characteristics• Improved strength, ductility (dry) and rigidity

SOLITEC
The multifunctional high performing water-based coating
ASK Chemicals water-based SOLITEC coatings come in two application varieties specially engineered for
non-automotive & specialty castings. Designed for safety and performance, SOLITEC assures exceptional
quality alongside a safe workplace environment. Application specialists utilizing the brushing method (i.e. a
method requiring close proximity) will enjoy the low-VOC advantage of SOLITEC. Additionally high- performance formulations (e.g. zircon free) vastly improve surface ﬁnish leading to reduced cleaning costs. SOLITEC
is also offered in several innovative color-changing formulations that visually represent when the coating is dry.
This unique characteristic ensures the integrity of your coating within your production process. Multiple applications are acceptable with SOLITEC coatings: brushing, spraying and ﬂow coating.

Benefits• Excellent release properties• Smooth application properties• Short air drying time & enhanced refractoriness• Environmentally friendly• Casting defect prevention

Specialty coating
ASK Chemicals has available several specialty-coating formulations designed for a specific purpose, whether
it be the need for a metal chilling effect, gas scavenging in light metals, or eliminating severe metal penetration
defects via the use of a premium primer coating. Below is a list of these unique coatings made available tosolve the most difficult of casting defects.
ASK Chemicals has also developed an innovative zircon-free refractory combination for heavy and thick-walled
iron, as well as most steel castings. In such extreme applications, it provides the same or even better casting
results as achieved with coatings containing zirconium. Two key advantages of zircon-free coatings include
low density and material handling.
Note: Please contact your ASK representative for details regarding our zircon-free coatings (not listed below).
