Depending on their formulation or the technologies used – RTV-1, RTV-2, gels, foams, etc. – adhesion can be modulated for different degrees of tack, from controlled adhesion to self-adhesion (chemical link). A wide range of additives can be integrated into silicone elastomers to ensure this specific characteristic. The adhesive features can be coupled to other performance requirements, such as electrical insulation or conduction, heat transfer capacity, fire and thermal resistance, etc. For example, silicone gels provide especially high levels of tack because of their intrinsic mechanical properties. Self-adhesive silicones are excellent for their shearing capabilities and outstanding flexible bonding. Silicone formulations can be designed to meet manufacturers’ needs, taking into account their production environment and process requirements.
