Platinum Cross-linking Agent

C -100AB

C-100AB,two component platinum addition type cross linking agent

Which is added in the raw silicones for the cross linking of food and medical grade silicone rubber items ,

The vulcanized products can pass the FDA test,

it features with non-toxic, odourless, high grade of transparency, well anti-yellowing and other properties.

Food Grade and Medical Grade，No secondary curing

Anti-yellow，High penetration

Low addition rate

C-100A: transparent paste, containing platinum and organic silicon polymer

C-100B: transparent organic silicon polymer, containing crosslinking agent and inhibitor

Hardness(ShoreA) : 50±5

Tensile Strength (Mpa) : 10~12

Elongation at Break(%): 500~540 Compression Set %(100℃/22h): ＜5

Specific Gravity: 1.1g/cm3

The raw material is easy poisoning once contact with nitrogen, phosphorus, sulfur and heavy metal materials.

C-100A and C-100B can not be added at the same time. First add C-100B into raw silicone and mixing evenly, then add C-100A into raw silicone. The addition order is important.

The temperature of mixing machine which used for mixing silicone with platinum curing agent can not be higher than 45℃. Please add this agent after being cold.

The mixed raw materials should be used up within two days

.Please choose the suitable raw materials for hot air vulcanization,unmatched raw material will cause bubbles in the process.

Type one: Extrusion Or Injection Moulding

1. For High Tear Strength Silicone Materials (filled with gaseous phase white carbon black) Application weight ratio:

C-100B 2.0~2.5%

C-100A 0.5~0.6%

Curing condition: IR(6meters),constant temperature ±5℃. First curing: IR curing at 190~200℃ for 40~60 seconds.

Finished curing: After first curing, it should be cured again as below conditions.

2. For Normal Silicone Material

Application weight ratio:

C-100B 1.5~2.0%

C-100A 0.5~0.6%

Curing condition:IR(6meters),constant temperature ±5℃.

First curing: IR(Infrared Radiation) curing at 140℃ for 40~50 seconds. Finished curing:After first curing, it should be cured again as below conditions.

Type two: Compression Molding

Application weight ratio:

C-100B 1.0~1.5%
