Application Scenarios
Plastic Toys Industry
HY-901 economical
Pad Printing Silicone rubber is widely used in the plastic toy industry. Toy products usually have complex shapes and irregular surfaces, requiring pad printing heads with good resilience and conformability. HY-901 has moderate hardness, which can perfectly fit various curvatures and unevenness on toy surfaces, transferring cartoon patterns, facial expressions, brand logos and other designs clearly onto toy surfaces. Its economical nature enables toy manufacturers to effectively control costs in mass production, while stable printing quality ensures clear and consistent patterns on every toy product.
Electronic Products Industry
In the electronic products industry, HY-901 is used for logo and mark printing on phone cases, remote controls, keyboard keys, headphone housings and other products. Electronic products have high requirements for printing precision, requiring clear pattern edges and accurate positioning. HY-901 has good dimensional stability and ink transfer performance, ensuring the precision and consistency of printed patterns. Its good ink solvent resistance allows the pad head to maintain stable printing effects after long time use, reducing the frequency of pad head replacement and improving production efficiency.
How to Use
Step 1: Prepare the pad head mold and clean the mold surface to ensure no dust, oil or other impurities. Apply a thin layer of release agent on the mold surface if needed for easy demolding.
Step 2: Accurately weigh Part A and Part B at a weight ratio of 100:2. Use an electronic scale to ensure accurate ratio, as ratio deviation will affect curing effect and pad head performance.
Step 3: Pour Part A and Part B into a clean container and mix thoroughly with a stirring rod for about 2 to 3 minutes. Scrape the sides and bottom of the container to ensure no unmixed dead corners.
Step 4: Place the mixed silicone in a vacuum degassing machine and degas for 3 to 5 minutes at 0.08MPa pressure to remove air bubbles mixed during stirring. The silicone surface should be smooth and bubble free after degassing.
Step 5: Slowly pour the degassed silicone into the prepared pad head mold from one side to avoid generating new bubbles. After pouring, gently vibrate the mold to help remove residual bubbles.
Step 6: Let it cure at room temperature for 2 to 4 hours. After the silicone is completely cured, demold it. It is recommended to leave it for 24 hours for post curing to achieve optimal pad head performance before use.

Precautions
It is recommended to wear nitrile gloves during operation to avoid direct skin contact with uncured silicone. Avoid silicone contact with substances containing nitrogen, sulfur, phosphorus, tin, lead, mercury, amines, alcohols, water and others, as these substances may cause incomplete curing or stickiness. Strictly weigh at 100:2 weight ratio accurately, as ratio deviation will affect curing effect. Mix thoroughly and evenly to ensure no unmixed dead corners. Curing temperature should not exceed 60 degrees Celsius, as high temperature will affect pad head performance. The operating environment should be well ventilated.
Storage
Products should be stored in a cool, dry and ventilated warehouse, avoiding direct sunlight and high temperature environment. Storage temperature is recommended between 5 and 35 degrees Celsius. Under unopened original packaging storage conditions, shelf life is 12 months. Seal the container lid immediately after each use to prevent moisture absorption and impurity contamination. Part B curing agent should be specially sealed for storage to avoid contact with air and 失效. Refrigerated storage can appropriately extend shelf life.
FAQ
Q: How many times can a pad head made from HY-901 generally be used?
A: Under normal operating conditions, a pad head made from HY-901 can print 50,000 to 80,000 times. The specific service life depends on factors such as printing surface material, ink type, printing frequency and operation standards.
Q: What should I do if printing becomes unclear after the pad head has been used for a while?
A: Ink residue will accumulate on the pad head surface after use. It is recommended to regularly clean the pad head surface with anhydrous ethanol or special cleaner. If it is still unclear after cleaning, the pad head surface may be aged. It is recommended to polish the surface or replace with a new pad head.
Q: What causes the silicone surface to be sticky after curing?
A: Surface stickiness is usually caused by inaccurate mixing ratio, insufficient mixing, or contact with inhibiting substances containing tin, sulfur or amines. Please check whether weighing is accurate, whether mixing is sufficient, and ensure that molds and tools are clean and free of contamination.
