What it bonds
Where the manufacturer names a material, we quote them. Where we have assessed it ourselves, we say so and grade it lower. The two are never merged.
| Material | Basis | Manufacturer wording |
|---|---|---|
| Fabric | Listed by the manufacturer A | “silicone rubber to silicone rubber and other substrates including some plastics (urethane), plasters/ceramics, fabrics” |
| Glazed ceramic | Listed by the manufacturer A | “silicone rubber to silicone rubber and other substrates including some plastics (urethane), plasters/ceramics, fabrics” |
| Silicone rubber | Listed by the manufacturer A | “silicone rubber to silicone rubber and other substrates including some plastics (urethane), plasters/ceramics, fabrics” |
| Unglazed ceramic | Listed by the manufacturer A | “silicone rubber to silicone rubber and other substrates including some plastics (urethane), plasters/ceramics, fabrics” |
Preparation
Clean and dry; abrade where possible, then solvent-wipe without pooling solvent on silicone.
Limitations
The broad secondary-substrate list does not name glass or stainless steel. Test the exact silicone formulation.
