A non-polar reaction resin mixture can be used to improve the adhesion of a mortar composition based on radically polymerizable compounds, in particular based on urethane (meth)acrylates, on the surface of semi-cleaned and/or damp boreholes in mineral substrates. The use of a non-polar reaction resin mixture in the corresponding mortar composition reduced the sensitivity thereof to dampness and inadequate cleaning conditions, so that mortar compositions are obtained overall which are characterized by improved robustness against external influences.

A curing composition is useful for a multi-component epoxy resin compound and includes at least one first polyamine, at least one second polyamine, and at least one polyphenol from the group of bisphenols and novolac resins as an accelerator. Upon contact with atmospheric oxygen, the curing composition discolors within a few days and therefore leakages can be visually identified.

A method of pouring a body, including mixing an isocyanate, a polyol, and a catalyst to yield an admixture, dispersing a particulate phase in the admixture to yield a homogeneous composition, pouring the homogeneous composition into a preform, capping the preform to prevent expansion of the homogeneous composition thereoutof, and curing the homogeneous composition to yield a polymeric composite body. The matrix portion is formed from a polymerizable formulation comprising at least one isocyanate precursor, at least one polyol, and a catalyst contained in a mold having a pressure rating of at least 0.4 Mpa. The at least one isocyanate precursor is selected from the group consisting of polymethylene polyphenylisocyanate, diphenylmethane diisocyanate, triphenylmethane triisocyanate, toluene diisocyanate and methyl diisocyanate (MDI), and combinations thereof. The catalyst is selected from the group consisting of a dialkyltin derivative, tributyl bismuth, and combinations thereof and is a tertiary amine.

Embodiments of the present disclosure provides a muscular tension releasing system comprising a therapy device comprising a first end, a second end, and an elongate rod extending from the first end to the second end. The rod includes multiple treads comprising knobbly bits; multiple receiving units to receive at least one tread; bearing surface(s) present on one of the first and second ends; and a coating of a durable material. The system also includes a strap including attachment unit(s) for attaching to at least one of the ends; and at least one holding means for enabling a user to hold the strap for positioning the therapy device according to a body part where the user wants to put pressure on. The strap enables the user to control an amount of pressure exerted by the therapy device on one or more muscles of the body part.
