In the printing and processing field, "difficulty in adaptation" and "single effect" are often troublesome problems—either the ink viscosity is inappropriate, the desired color cannot be mixed, or the printed pattern is prone to wear. However, the emergence of the GF(D,E)9730 and 9730-50 series ink-type liquid silicone rubbers is breaking these limitations with their flexible properties, becoming a "good helper" for printing practitioners.
In terms of appearance, both products are pure transparent liquids without impurities or turbidity, just like clear purified water. This means that when mixing colors, they will not be interfered by the base color, enabling accurate reproduction of the desired color tone. What is more reassuring is that they comply with two major international standards: US FDA and EU RoHS. Whether printed on food packaging or the surface of children's products, there is no need to worry about safety issues, making them environmentally friendly and reliable.
In terms of performance, their "durability" is even more surprising. After curing, the Shore A hardness of both products is stably maintained at 30. This hardness is similar to that of soft silicone, which has a certain degree of support while not being too brittle. When printed on a phone case, the pattern will not easily crack when the phone is dropped; when printed on a silicone wristband, the paint will not peel off even after repeated bending. Looking at the tensile and tear properties, the tensile strength is ≥3.0MPa and the elongation at break is ≥400%, which is equivalent to stretching the printed coating 4 times without breaking. The tear strength is ≥10.0KN/m, so daily friction and scratches will not damage it at all, greatly extending the service life of the printed pattern.
The most flexible aspect is its process adaptability. If the original viscosity is not suitable for the current printing method—for example, screen printing requires slightly thicker ink and spray coating requires thinner ink—you only need to add an appropriate amount of solvent to adjust the viscosity like "adjusting the concentration of milk tea", easily adapting to three mainstream processes: screen printing, pad printing, and spray coating. Changing colors is also simple; by adding different color concentrates, various color tones from bright red to calm black can be easily mixed. Whether printing uniform patterns in batches or customizing personalized designs, it can meet the needs.
