Two component silicone sealantSI3630 A/B
Detailed Product Description
SI3630A/B is two component RTV addition type silicone sealant. The curing will be faster if heating, the highest heating temperature is 150°C.
1.Easy to cure, 30min in 100°C
2.Excellent mechanical property and dimensional stability
3.Simple application, Speedy mixed by 10:1. The strength and hardness can be adjusted by change the amount of curing agent.
4.High hardness, low curing shrinkage, < 0.2 %
1.Use in duplicate of sample plate, prototype, electronic component, construction and furniture parts.
2.Also use to rolling over of polyurethane foam products, making of rubber roll and nozzle.
3.Use to make adhesive layer of lace ribbon climbing clothes.
1. Mix Part A and Part B by 100:10,The two parts can be mixed by hand work or pneumatic pump, try best to avoid the bubbles and temperature rising.
2. Pouring, the mixed sealant should be degassing by vacuum 30-50 mbar for removing the wrapped bubbles. If using dispersion equipment, the two parts need to be degassing separately before mixing.
The volume will expand to 3-4times while the mixed sealant degassing, then shatter, it will recover after 5-10mins.
The materials may influence the curing:
1. Natural rubber which is vulcanized by sulfur
2. Silicone rubber which is catalytic by metal salt like Sn salt
3. PVC which is made with Sn salt and additive
4. Epoxy resin which is catalytic by amine
5. Some organic solvent, such as Ketone, alcohol, ether etc.
Package and Storage
Part A: 20kg or 180kg Part B needs to be sealed and avoid light and hot
Part B: 2kg or 18kg Shipped and stored as normal chemicals
Shelf life: 12 months(25°C)
