Base Materials for 2-part Silicone Formulations
Silicone-based 2-part formulations are used in many applications. These include dental impression materials and other elastic molds, as well as adhesives, coatings, casting and encapsulating materials for electrical and electronic applications.
Metal catalysts based on platinum are needed in order to cure vinyl-functional silicone polymers with SiH-functional silicone crosslinkers . hanse chemie offers a highly reactive, neutral platinum catalyst that need to be added only in very small quantities (as a rule, 10-50 ppm in a formulation is sufficient). The active platinum catalyst is therefore not offered concentrated, but rather as a dilute solution in a vinyl-functional silicone polymer.
Highly reactive, neutral platinum catalyst. Used to cure vinyl-functional silicone polymers with SiH-functional silicone crosslinkers for the manufacture of addition curing formulation such as 2-part silicone formulation for coatings. Allows addition of very small quantities. <br>
Use level: 10-50 ppm in a formulation.
