Tin Cure Silicone Rubber RTV-6 series — (Economical item)

RTV-6 series Silicone Rubber is a two-component material consisting of Base which when mixed with a Curing Agent, cures at room temperature by a condensation reaction. A range of materials can be cast into the cured silicone mold: plaster, polyurethane, and polyester resins are materials typically used.

Key features

  • Good strength
  • Good elasticity, for easy removal of, complex replica parts
  • Pourable
  • Less shrinkage
  • Outstanding release properties

Applications
RTV-6 Series silicone rubber is designed for molding gypsum, concrete, GRC, polyurethanes, polyester resins, plasters, waxes, soaps, paraffin, liquid plastics, as well as for the production of souvenirs, sculptures, figurines and other handicrafts.

Instruction

  1. Stir Part A well before use, shake Part B catalyst container well before use.
  2. Weigh 100 Part A to 2~3 Part B using an accurate scale and a clean mixing container.
  3. Vigorously mix and scrape walls of the container, continue mixing until uniform.
  4. Place the mixture in a vacuum chamber & degass. If without a chamber, Pour the mixture 2-3 inches above the pattern in a thin stream.
  5. Allow the silicone to cure 2-4 hours and demold with care.

Important tips

  • Before use, read the operation manual, please.
  • Before large production, a small-scale test is recommended.
  • Mixing ratio must be accurate, recommend mixing ratio is A:B=100:2~3(by weight), If curing too fast, please reduce the ratio of catalyst to 1% or less, then Stir Part A and Part B completely.
  • Use a vacuum to de-gas this product before use under pressure. Vacuum silicone for 2-3 minutes
  • This product has a limited shelf life. Use it as soon as possible after opening.
  • Always tightly reseal containers after use. Air, moisture or other contamination causes a reduction in reactivity over time.

Package

Storage & shelf-life

12 months in unopened containers when properly stored.

Super-Silicon cannot guarantee the shelf life of opened or repackaged units.
Recommended storage temperature range: 10°C – 25°C. SuperSilicon™ should be stored in closed containers out of direct sunlight and away from direct sources of heat. Always tightly reseal containers after use. Air, moisture or other contamination causes a reduction in reactivity over time.

Mold Making Materials COMPARISON

Tin cure silicone VS. Platinum cure silicone

Type
Advantages
Disadvantages
Casting materials
Tin-Cured Silicone
High strength, Cost-effective
Shrinks on cure (~0.3%), Cured rubber has limited storage life, Not food-grade
Most materials, especially resins, foams, plaster, wax, concrete etc.
Platinum-Cured Silicone
No shrink on cure, Cured rubber has long storage life, Excellent chemical resistance, Food-grade skin safe, 1:1 simple mix
Cure inhibited by some materials, a slight expensive than tin cure silicone
Most materials, especially resins, foams, plaster, wax, concrete etc. and some low-melt metals and food grade products mould.
