Harden Time (surface) : 20-45 mins pot life, 4-6 hrs cure, complete harden 24 hrs
Shore A Hardness: Approx. 25
Tensile Strength: Approx. 4.0 MPa
Ultimate Elongation: Approx. 500-550%
Tear Strength: > 24 kN/m
Linear shrinkage 3% slow speed catalyst
Color:
White
Content:
1KG / 5KGS / 10KGS
Description:
Mold silicone rubber is a two-component silicone rubber at room temperature, abbreviated as RTV.
This is a two-component compound.
The A component contains a crosslinking agent and the B component contains a catalyst.
During the packaging process, the crosslinker and the catalyst must be separated.
Its vulcanization is carried out at room temperature, as long as the two components are mixed in a certain ratio.
The two-component compound undergoes a cross-linking reaction to form a flexible and elastic colloid.
Nature:
(1) Good chemical stability, non-toxic and non-corrosive;
(2) Good fluidity, can fill the mold automatically;
(3) Controllable vulcanization speed, vulcanization at room temperature and normal pressure, easy to operate;
(4) Good demouldability;
(5) Strong simulation and realistic decoration;
(6) The mold making speed is fast, and the mold can be made within 20h.
Operation method:
1. Stir the silicone and curing agent evenly. Component A is silicone, Component B is the curing agent.
Example: Take 100 grams of silica gel and add 2-3 grams of curing agent (stir evenly).
2. Vacuum exhaust air bubble treatment: Remove bubbles after mixing, not exceeding 10 minutes.
3. Painting or operation process: Brush or pour silica gel onto the product, apply gauze and weft cloth for reinforcement.
4. Production of outer mold: Surround mold with rubber sheets or wooden boards, fill with plaster or resin layers.
5. Filling or pouring molds: Use for simple products, pour vacuumed silicone directly onto the model, ensure demolding ease.
Use:
Suitable for slicing brush molds, such as cement products, cultural stones, sandstone reliefs, resin crafts, tire molds, etc.
Instructions:
Read the user guide carefully before use.
Safety: Use in a ventilated area, wear safety glasses, long sleeves, and vinyl gloves.
Store material at room temperature; premix Parts A and B thoroughly.
Cure Inhibition: Test small area for surface contaminants to avoid uncured rubber.
Apply sealing agent if necessary.
Applying a release agent: Optional, recommended for demolding.
Measuring & Mixing: Mix Parts A and B thoroughly, scrape container sides.
Vacuum treatment: Do not exceed 10 minutes.
Pouring: Pour at lowest point, allow rubber to flow evenly.
Curing: 75 minutes at 23°C before demolding, post-cure 4 hours at 65°C.
Using the Mold: No release agent needed for wax/gypsum; recommended for polyurethane, polyester, epoxy.
Mold Performance & Storage: Clean mold before storage, store level in cool, dry environment.
