RTV2 Condensation Cure Liquid Silicone Rubber High Tear Strength Low Shrinkage For Architectural Culture Stone Molds

Description of Tin Cure Silicone Rubber

Feature of Tin Cure Silicone Rubber:

1. Zero cure inhibition

Compatible with nearly all model materials, no sticky uncured residues after curing

2. High tear & tensile strength

10–35 Shore A flexible molds, easy demolding for complex undercut sculptures without breakage

3. Great flow property

Low viscosity fills tiny gaps to restore every micro detail sharply

4. Economical option

Professional molding performance at far lower cost than platinum silicone for better profits

5. Customizable curing speed

Adjust tin catalyst proportion based on workshop temperature to slow down or accelerate curing process

​

Application of tin cured silicone rubber:

▪ Statue & Sculpture Casting: Reproduce detailed concrete, gypsum, plaster & resin artworks

▪ Architectural Restoration: Molds for cornices, stone veneers and building decorative parts

▪ Arts & Crafts: Durable molds for candles, soap and polyurethane craft casting

Operation method:
1. Mix the mold adhesive and curing agent in a weight ratio of 100:2-3 and stir evenly;
2. Place the mixed and stirred silicone gel into a vacuum machine for vacuum exhaust bubble treatment. The advantage of doing so is to make the product smooth and free of bubbles (without a vacuum machine, the curing time can be extended to allow bubbles to naturally discharge, but the effect is not very ideal);
3. Spray (apply) a layer of release agent on the already made mold and mold frame, fix the mold in the middle, and slowly and steadily pour the liquid silicone that has discharged the bubbles into the mold frame until the silicone completely covers the mold, and then let it rest until it fully solidifies;
4. Wait until the silicone gel of the mold is fully cured before demolding, and remove the silicone mold for edge treatment;
5. It is recommended to leave the silicone mold for 24 hours before putting it into use, in order to achieve the best use effect of the mold.
