Silicone Hydrographic Printing Primer
Overview
Silicone hydrographic printing primer is a special primer developed for hydrographic transfer printing on high-temperature vulcanized silicone rubber products. Since silicone rubber is a non-polar material, conventional adhesives often fail to achieve satisfactory results.
This primer is specially used for surface treatment of silicone rubber. It can effectively improve the surface polarity of silicone rubber and greatly enhance bonding performance. After treatment, silicone rubber also delivers good results for painting and screen printing. Apply it onto high-temperature silicone sheets, then perform hydrographic transfer printing, so that the hydrographic pattern can be transferred onto the silicone substrate.

Instructions for Use
1. Wipe contaminants (oil, release agent, etc.) off the bonding surface of the silicone rubber substrate with toluene.
2. Apply the primer onto the pretreated substrate by printing, brushing or spraying, and keep the coating as uniform as possible.
3. Place the coated sheet on a rack for air drying at room temperature:
- Fast-dry type: 5–15 minutes
- Slow-dry type: 30–60 minutes
Prevent dust contamination during drying.
4. Hydrographic printing can be carried out after full drying.
Application Scope
Silicone primer is widely used for hydrographic transfer printing on silicone rubber foot pads, silicone ornaments and other silicone parts.
Precautions
1. Seal the bottle cap tightly after use.
2. Flammable. Keep away from fire and heat sources; store in a cool and dry place.
3. Excess primer can be cleaned with a cloth dipped in thinner.
4. Shake well before use for better performance. 3–5% curing agent may be added for stronger performance if required.
