Food Safe Optional Silicone PU Coating Ink Water Resistant PU Paint For Silicone Kitchen Gadgets

Silicone Rubber Polyurethane (PU) Coating Ink 

Product Description

Exhibiting excellent interfacial adhesion and elastomeric compliance, this PU ink is optimized for low-energy surfaces such as silicone and rubber. Its crosslinked film offers high mechanical durability, chemical inertness, and UV/weather stability. Rapid photochemical or thermal curing yields high-chroma prints with a low-modulus, soft-touch haptic response.

Application

Mainly applied to silicone cellphone case, silicone keypad and other silicone rubber products.

Application Ratio

Silicone ink: 100g

Mixer(catalyst): 2~3g

Thinner: 300~500g

Processing

Pay close attention to the timings: you have a 5-to-10-minute window for mixing the ink and catalyst (at a 100:2-3 ratio) in a barrel after diluting it with 3 to 5 rounds of White Gas or Xylene. Filtration must happen twice through a 300-mesh screen right before the spraying phase. Most critically, your operational clock starts ticking once mixed—you have a hard limit of 12 hours to use it. Throughout this timeline, the ambient temperature must never deviate from 22°C.

All the above physical data only for reference.
