Use of a stable indole-nitroxide radical as a stabilizer and/or inhibitor for resin mixtures and reactive resin mortars is described on the basis of radically curable compounds. Resin mixtures and reactive resin mortars may be made stable in storage very effectively using the indole nitroxide radical and the pot life of mortar compositions can be adjusted in a targeted manner.

Provided is a thermally conductive silicone gel composition having high thermal conductivity, excellent extrudability and mixing stability, resistance to separation of each liquid even in a two-component package, stable storage, and superior gap fill properties for heat dissipating components, and the like.

A double coating, curing method, cured coating, and kit are provided. A first layer of the double coating can be a first cure coating composition, which has a first hydroxy-functional resin, a first crosslinking agent, and a first catalyst. A second layer of a second cure coating composition can have a low hydrophilicity acrylic resin as a second hydroxy-functional resin, a second crosslinking agent, and a second catalyst. The first catalyst catalyzes crosslinking between the second hydroxy-functional resin and crosslinking agent, and not between the first hydroxy-functional resin and crosslinking agent. The second catalyst catalyzes crosslinking between the first hydroxy-functional resin and crosslinking agent, and not between the second hydroxy-functional resin and crosslinking agent. The first and/or second hydroxy functional resins can facilitate catalyst migration from one layer to the other. The separate compositions can be shelf-stable and/or the curing can occur at low temperature.
