Silicone curing agent

详情

C ***0A/B Platinum cross-linking agent
C***0A and C***0B belongs to platinum addition type cross linking agent and can be approved
by FDA after cured, also characterized by non-toxic, odourless, high transparent and well
anti-yellowing.The materials can be cured again if low-molecular -weight is strict by request.
This agent are mainly applied to Food Grade and Medical Grade products, such as nipples, cake
mold, silicone cookwares, medical silicone tube and so on, also can be used for extrusion
products and mobile phone keypad.
Component:
A: Platinum catalyst B: Organosilicon polymer
C: Silicone cross-linking agent D: Vulcanization retarders
Physical Properties: (Tested by KE***1U Gel)
Appearance: Milk white or semitransparent light yellow
Specific Gravity（*3℃） 0.9~1.0
Hardness(ShoreA) *9~*1
Tensile Strength (Mpa) *0~*3
Elongation at Break(%) **0~**0
Cracking Resistance(KN/m) *4~*7
Compression Set %(**0℃/*2h) ≤5
Notes:
1. Avoid to contact with nitrogen, phosphorus, sulfur and heavy metal materials,they will cause
dead materials.
2. The cross linking agent is added by weight to Part B and should be thoroughly mixed into Part
A after adding Part B,the order is important. A and B can not be mixed together.
3. The temperature of mixing machine which used for mixing silicone with this agent can not be
higher than *5℃.Please add this agent after being cold.
4. Thoroughly vulcanized materials by this agent must be used up within two days.
5. Pleas choose the suitable raw materials for hot air vulcanization, bad raw materials will cause
bubbles.
