The silicone ink is of pasty form ,it cures to be silicone rubber on exposure to heat. With the Silicone Ink you can print on any items made of silicone rubberincluding custom silicone wristbands, cellphone covers, swimming caps, keypads,anytypeof popular promotional items made of siliconerubber
The Silicone Ink is ofgloss and mattfinish and has greatelasticflexibility and abrasion resistance, waterproof and heat resistance.
Part A: Platinum catalyst
Part B: Ink
Appearance: Pasty form
Solvent: Aviation kerosene(white gasoline or white gas)
Specific Gravity: 1.05
Mixture weight ratio: A:B=0.02:1
Color: Pantone Code Colors
1.Rubclean the surface of silicone rubber items with normal kerosene-dipped cloth (thinner or white gas also do)
2. Mix 2% of the catalysts with special solvent like thinner or kerosene (10%±3%) appropriately.
3,Mix evenly the ink with catalysts-added solvents
4. Get the printing area of silicone rubber item hot with flame treatment(heating) before printing on with ink
5. Pouring the thoroughly mixed ink on the screen printing plate for printing the ink on the still hot products’surface.
6. Baking method:
A.Vertical oven: Baking at 180℃for 20-50 minutes.
B.Horizontal oven: Baking at 200℃for 8-10 minutes.
C.IR strip: Baking at constant temperature 200℃for 8-10 minutes
To achieve ideal adhesion of ink to rubber, make sure you clean the silicone rubber surfaces to remove dirts or dust, rub the sand paper against rubber surfaces if rubber had extra coating on it which affect adhesion and don’t forget get the silicone rubber hot before printing on with ink
No addition or less addition of catalysts render ink hard to dry in baking process
Please add (10%±3%) solvent, adding solvent over this proportion to save cost will result in poor color appearance
