Liquid RTV-2 Mold Making Silicone Rubber
Condensation cure system
Applications of RTV2 Moulding Silicone Rubber:
Silicone flexible molds are used for mold duplication and delicate mold making for poli resin crafts, lighting, gypsum and concrete crafts.
Features of RTV2 Moulding Silicone Rubber:
RTV-2 molding silicone rubber are generally named two -component room temperature vulcanization silicone rubber, a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion.
Instructions of RTV2 Moulding Silicone Rubber:
RTV-2 molding silicone rubber are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours.
P series RTV-2 Silicone is good for mold making by pouring

Storage of RTV-2 molding compound silicone
When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
Package of RTV-2 molding silicone rubber
Part A base silicone: 20kg/drum, 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle and 10kg/bottle
