Abstract: A composition that forms an insulating layer contains an epoxy-thiol-based binder. Because the expansion rate of the composition is relatively high, coatings having the layer thickness required for the relevant fire resistance duration can be applied in a simple and rapid manner, and it is possible to reduce the layer thickness to a minimum while still achieving a good insulating effect. The composition is particularly suitable for fire-protection, in particular as a coating for metal and non-metal substrates, e.g., steel components such as supports, beams, and truss members, to increase the fire resistance duration thereof.

Abstract: A foamable, insulating-layer-forming multi-component composition contains alkoxysilane-functional polymer, insulating-layer-forming fire-protection additive, blowing-agent mixture, cross-linking agent, and a flame-protection agent that is miscible in water or another compound that is miscible in water. The individual ingredients of the blowing-agent mixture are separated from one another to ensure inhibition of reaction prior to use of the composition, and the cross-linking agent is separated from the alkoxysilane-functional polymer to ensure inhibition of reaction prior to use of the composition. The foamable, insulating-layer-forming multi-component composition can be used as a foam-in-place foam or for production of molded blocks.

Abstract: A setting method for expansion anchors via an impact wrench has a first phase S1 and a second phase S2. In the first phase, a rotary impact is repeatedly exerted on a screw element of the expansion anchor and a torque transmitted from the rotary impact to the screw head is estimated. The first phase S1 is ended when the estimated transmitted torque exceeds a threshold value specified for the expansion anchor. During the second phase, a first number of rotary impacts specified for the expansion anchor are exerted on the screw head. A current rate of change of the estimated torque is monitored at least during the first phase. In response to the current rate of change exceeding a limit value for the rate of change specified for the expansion anchor, a modified second phase is started, in which a second number of rotary impacts specified for the expansion anchor are exerted on the screw head, the second number being less than the first number.
