GOLDEN Silk-Screen Fabric Gel is
a water-borne system designed to blend with acrylic paints for
silk-screen application onto cotton, 50/50 cotton/polyester blend
fabrics, and other garments. This product gives paint a soft,
pliable feel and when properly heat-set, provides excellent laundering
stability. Silk-Screen Fabric Gel also increases working time
and retards paint from drying in the screen.
NOTE: GOLDEN Silk-Screen Fabric Gel is not designed for application
onto materials not intended to be washed, such as paper, wood
and canvas. For these and other fine art applications, use GOLDEN
GOLDEN Silk-Screen Fabric Gel can be blended with any
of the GOLDEN Acrylic Paint Lines to lengthen the working open
time1 for silk-screening. It is a pourable blend
of a unique acrylic, retarder & water that, unlike retarder
alone, will form a film. This increases durability while thinning
and retarding the drying time.
Although any addition of GOLDEN Silk-Screen Fabric Gel will increase
the open time of a paint, a good starting point is to blend even
parts of paint and medium. Higher levels of the medium will increasingly
affect the transparency, but also will increase the open time.
Lower levels of Silk-Screen Fabric Gel produce mixes with the
greatest opacity, but that are more likely to clog in the screen.
These mixes may also not have a satisfactory softness of hand.
Altering Opacity of a Mixture
Silk-Screen Fabric Gel is not designed to impart opacity.
The opacity of the mixture will be determined by the nature of
color being used and the ratio of paint to medium used. Adding
GOLDEN Titanium White to a mixture will also increase opacity.
Any addition of white will lower a color's chroma and value. Consult
GOLDEN Pigment Identification Chart to determine the opacity ratings
for the various colors.
Higher levels of the Silk-Screen Fabric Gel will be increasingly
more transparent. If highly transparent colors are desired, try
keeping the amount of Silk-screen Fabric Gel or GAC 900 near 50%
of the entire blend to ensure a tack-free film. We suggest adding
GOLDEN Soft Gel Gloss to the mixture to adjust transparency. Testing
mixtures is important as each color varies in opacity. One method
for adjusting color is to first create a mix with just Soft Gel.
Once the screened film is dry, replace part of the Soft Gel with
Silk-Screen Fabric Gel for the actual printing run.
Additionally, transparent colors, including Iridescent and Interference
Colors, can be made to appear more opaque when a base coat2
is screened first. For example, GOLDEN Iridescent Gold will appear
to have greater opacity over a buff-colored base coat. Refer to
screen-printer's reference material for further suggestions.
Hand-Brushing with Silk-Screen Fabric Gel
GOLDEN Silk-Screen Fabric Gel and GAC 900 can be used to hand-paint
fabric as well. Although these mediums were intended for screening
applications, it is not limited to it. Follow the blending and
heat-setting directions the same as for screening.
Thickness, or "viscosity," can greatly influence
how a printing ink performs. Thinner inks have a greater risk
of "bleeding" into fabric or other porous substrates,
but perform well on tighter mesh screens and dry quickly on fabric
and other absorbent surfaces. Thick, pasty mixes have a higher
tendency to clog tighter mesh screens, but can offer an increased
opacity (due to a thicker film) and are less likely to bleed when
screened onto fabrics. These considerations should be addressed
before beginning large printing runs.
Choosing a line of GOLDEN Acrylic Paints to use with the Silk-Screen
Fabric Gel is dependent on the artist and the thickness they need
for a particular job. GOLDEN Heavy Body Acrylics have a buttery
viscosity and make thicker screening inks. GOLDEN Fluid Acrylics
have the same pigment load as our Heavy Body Paints, but are the
consistency of heavy cream, and are quite pourable. Mixtures should
remain thin and pourable.
Blending with GAC 900
Viscosity may also be altered by thinning with GAC 900. This
product (one of GOLDEN'S Specialty Acrylic Polymer Mediums), is
essentially the same formulation as the Silk-Screen Fabric Gel,
but has not been thickened quite as much. By adding amounts of
GAC 900 to the gel, only the overall thickness will be altered.
Improving Working Time
While Silk-Screen Fabric Gel dramatically retards3
the paint from drying in the screen, it does not eliminate the
possibility. As soon as a clog becomes apparent, it should be
removed with a damp cloth. If the clog is allowed to dry in the
screen, it will be extremely difficult to remove. For multiple
clogs that develop, stop printing and thoroughly clean screen
with water, using a non-abrasive sponge or cloth to remove the
clogs. Pat the screen dry and continue printing.
Work quickly, with minimal time between prints. Have screening
inks pre-made in sufficient quantities before beginning screening.
To maximize open time, add 5 - 15% GOLDEN Retarder to the GOLDEN
Silk-Screen Fabric Gel/Paint mixture. This will increase the open
time without dramatically altering the opacity4.
It is beneficial to pre-wet the screen with a water/Retarder mixture
(1:1) before screening. Keep a plant mister bottle filled with
this mixture at hand, and lightly spray the screen periodically
to prevent paint from drying. Avoid excessive misting, as this
can cause bleeding5 on the fabric.
Heat-Setting and Laundering
Heat-setting: Fabrics treated with GAC 900/Silk-Screen
Fabric Gel-modified paints must be heat set for maximum launderability.
The polymer must first air dry to the touch to form the initial
bond with the fabric, followed by one of the heat-set methods
Heat Press according to press manufacturer's recommendations.
Iron for 3-5 minutes with a medium-hot iron on the reverse
side (side opposite of the application). On delicate fabrics where
lower heat levels must be used, a longer ironing time will be
Professional Oven cures for 1-2 minutes at 300F; 4 minutes at 250F.
Clothes Dryer: Commercial: medium-high temperature for 20-40 minutes. Household: high temperature for 40-50 minutes.
Laundering Recommendations: Let paint dry thoroughly (at
least 4 days) before washing. Heat setting is recommended. Hand
washing will dramatically increase garment life. Set washer to
gentle cycle. Always turn garment inside out for laundering. Avoid
hot water washing. This will tend to soften the acrylic paint
and lead to loosening from the garment. Cold water works best
for automatic washing of the painted garment. Drip-drying instead
of using the clothes dryer will increase the life of the garment.
