For solventborne anticorrosion paints. Superior chemical resistance. Outstanding adhesion to concrete. The possibilities of polymer systems based on aliphatic-amine curing agents were systematically investigated last century, and the use of cycloaliphatic amines allows one to obtain adhesives, compounds, and matrices for composite materials with improved technological and operational characteristics [5, 6]. However, the classification of salicylic acid as a CMR (carcinogenic/mutagenic/reprotoxic) substance has caused its use in formulated products to be re-assessed. Use this grade where the lowest lead and higher SA is required and standard grade 112 USP is not suitable in the application. Trigonox 29-C90 is used for the crosslinking of natural and synthetic rubbers, as well as thermoplastic polyolefins.

The term "curing" is generally used in the processing of plastics, varnishes, adhesives, and sealing compounds. Underwater cure. The right curing agent depends on the base polymer, the processing conditions, and the physical and service requirements of the finished compound. The curing process can be monitored by measuring changes in various parameters: Ultrasonic cure monitoring methods are based on the relationships between changes in the characteristics of propagating ultrasound and the real-time mechanical properties of a component, by measuring: Gregory T. Carroll, Nicholas J. Turro and Jeffrey T.
