Silicone Rubber for Pad Printing Heads (Condensation-Curing/Addition-Curing)

Condensation-Curing:

Overview:

This silicone rubber, specially designed for pad printing heads, is a two-component condensation-curing silicone rubber.

It consists of Part A (base) and Part B (curing agent). When mixed, the two components cure at room temperature to achieve rapid molding.

Features:

1. Simple operation with room-temperature curing.

2. High tensile strength and tear resistance.

3. Excellent resilience.

Applications:

Suitable for transferring patterns onto ceramic plates, ceramic bowls, toys, plastics, handicrafts, and stationery.

Processing Instructions:

1. Measure the required amount of Part A and mix it with silicone oil in a specified ratio. Stir thoroughly, then add Part B according to the designated weight ratio and mix well. Pour the prepared pad body silicone into the mold.

2. When the pad head is nearly fully cured, pour in the prepared base silicone.

3. After demolding the finished pad head, place it on a flat surface and pour coating silicone over it to form a smooth, scratch-resistant surface layer.

Storage:

To maintain product quality, store in a dry environment at room temperature (25°C), sealed in its original container.

Standard Packaging:

Available in 20kg/25kg pails or 200kg drums.

Addition-Curing:

Overview:

This addition-curing silicone rubber for pad printing heads is a two-component liquid silicone rubber. With the proper amount of crosslinker added, it undergoes full vulcanization during heating, forming a flexible elastomer.

It consists of two components, Part A and Part B, mixed at either 10:1 or 1:1 ratio.

Features:

1. High tensile strength and tear resistance.

2. Excellent resilience.

Applications:

Suitable for transferring patterns onto ceramic plates, ceramic bowls, toys, plastics, handicrafts, and stationery.

Processing Instructions:

1. Measure the required amount of Part A into a container that is 3–4 times larger in volume. Add Part B according to the mixing ratio of 10:1 or 1:1 by weight, and stir thoroughly until fully blended. After vacuum degassing, the mixture is ready for use.

2. Working and curing times can be adjusted according to customer requirements.

Storage:

To maintain product quality, store in a dry environment at room temperature (25°C), sealed in its original container.

· Avoid contact with moisture or water vapor to prevent increased viscosity or changes in working time.

· Be aware that compounds containing phosphorus, sulfur, amines, or organotin may poison the catalyst and cause incomplete curing.

Standard Packaging:

Available in 20kg/25kg pails or 200kg drums.
