Classification of RTV-2 Silicone Rubber

Silicone their packaging can be divided into single-component, two-component silicone rubber; their curing methods, and can be divided into condensation silicone rubber and silicone rubber.

　　Silicone their packaging can be divided into two categories:

　　1, single-component silicone rubber: one-component silicone rubber is the difference between two-component silicone named. Two-component silicone type, the single-component silicone into a harmonic need not adhesive prior to use (curing agent) have been added to the single-component silicone formulation in the production of a latent curing agent was added. Such a curing agent is generally suitable temperatures encountered in either water or a suitable molecule can start curing reaction.

　　2, two-component silicone rubber: Two-component silicone is different from the one-component silicone ear named. Such plastic constituted by two components, the need to reconcile the two components together to cure.

　　By vulcanizing silicone can be divided into two categories:

　　1, silicone rubber is a synthetic rubber, silicone sequence belongs. This kind of flexible silicone gel silicone rubber and silicone rubber of the points, the lower the intensity of the former, the latter a higher intensity. Silicone rubber vulcanized rubber front lower viscosity, easy perfusion, and hold heat curing, no low molecular weight byproducts released, shrinkage, to the depth of cure.

　　2, condensation of moisture at room temperature vulcanizing silicone rubber is, the temperature and humidity of the air that it will be a great demand. Condensation-type silicone is through moisture in the air outside to the inside of vulcanization.
