JC-B202 (Platinum vulcanizing agent)
An instruction manual
JC-B202 is a double component addition molding silicone vulcanizing agent,
A/B can be used to achieve the purpose of silica gel molding. Platinum curing agent has the following characteristics: low curing temperature, vulcanization speed; after vulcanization, intermolecular crosslinking is enough; products after vulcanization are tasteless; through EU ROHS, LFGB and FDA food grade certification.
Sulfur adding methods: oil pressure plus sulfur, hot air and sulfur.
Vulcanization: extrusion high temperature vulcanization / calendering
Recommended use ratio: A:0.5%-0.6% B:1.0%-1.2%
Sulfur adding temperature: 120-220 C
Sulfur adding time: 120-150 centigrade, depending on the needs of the product

Mixing method: 20KG
Glue as an example: A agent: 0.5% x 20KG =100 G
B agent: 1% x 20KG = 200 g
Take the 10KG B agent of silica gel and 200 grams of mixing evenly, static cooling. Take 10KG 100 grams of silica gel and A agent mixing uniform, static cooling. Before the vulcanization, the A and B glue which are equal to the same quantity can be mixed with each other and can be used for vulcanization. A glue and B glue can be used in 4 hours to 8 hours to prevent crosslinking at room temperature. If A glue and B glue are mixed with each other for longer storage time, the delay agent must be added, and the amount of use depends on the need, but the more the retarder is to add sulfur, the slower the rate is.

Matters needing attention：
1. the addition of nitrogen, phosphorus, sulfur, lead, do Neki and other substances is prohibited, because the above substances can invalidation of platinum poisoning and can not reach the purpose of crosslinking.
2. some organosilicon adhesives will also cause platinum poisoning to be ineffective and can not be used. Therefore, when the vulcanizing agent is selected to produce it, the small test must be confirmed to be practicable.
3. after adding the silica gel of platinum vulcanizing agent, it is s ested that it is vulcanized in 4-8 hours to prevent the crosslinking at room temperature. If you need to extend the preservation time, can add a little delay agent (not included)
When there is hydrogen containing silicone oil in 4. silica gel, the extruded products are easy to produce bubbles.
When there is hydrogen containing silicone oil in 5. silica gel, the rubber will die when the A agent is mixed.

Product appearance: A agent: transparent glue
B agent: transparent glue
Product packaging: 1KG, 5KG, 20KG/ cans
Duration of preservation: six months
Storage and transportation
1., avoid high temperature and direct sunlight. Acid substances, metal oxides, amines and flammable materials should be stored in dry and shady places at room temperature below 25 degrees.
