SEMICOSIL® 9882 A/B

1 of 27 products in this brand
SEMICOSIL® 9882 A/B is a two-component silicone rubber adhesive that exhibits thixotropic properties and cures at moderate temperatures. It has a thixotropic, pasty consistency, making it easy to apply and work with. This adhesive offers low hardness and low modulus, resulting in excellent compression-set properties and high elongation.

Product Type: 2K (2 component) Adhesive

Application Area: Cure In Place Gasket, Electronic Control Unit (ECU), Form In Plastic Gaskets (FIPG), Housing, Power Control Unit (PCU)

Processing

Surface Preparation

All surfaces must be clean and free of contaminants that will inhibit the cure of SEMICOSIL® 9882. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds. If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.

Mixing

Component A of SEMICOSIL® 9882 contains the platinum catalyst, component B the crosslinker. Even traces of the platinum catalyst may cause curing of the component containing the crosslinker. Therefore tools (spatula, stirrers, etc.) used for handling the platinum-containing component or the catalyzed compound must not come into contact with this component. The two components should be thoroughly mixed at a 1:1 ratio by weight. To eliminate any air introduced during mixing or trapped under components or devices a vacuum de-airing under a vacuum of 10 – 20 mm mercury for 5 – 10 min is recommended.

Curing

Curing time of addition-curing silicone rubber is highly dependent on temperature, silicone amount, size and heat sink properties of the substrate the silicone is applied on. We recommend running preliminary tests to optimize conditions for the particular application. SEMICOSIL® 9882 shows good primerless adhesion to many substrates. We recommend running preliminary tests to optimize conditions for the particular application.
