ASI 306

ELECTRONIC GRADE SELF-LEVELING SILICONE

BONDS, SEALS, POTTING, ENCAPSULATES & ADHERES

ASI 306 Electronic Grade Self-Leveling Silicone is a one component, RTV (room temperature vulcanizing) product that can be used for encapsulating, coating and sealing.

No acetic acid or other corrosive by-products are generated during its cure which allows the ASI 306 to be used around sensitive metals and electronics. ASI 306 cures at room temperature to form a tough, high-modulus rubber. ASI 306 has excellent unprimed adhesion to a very wide range of substrates including metals (i.e. chrome), glass, most woods, ceramics and various plastics. ASI 306 will resist weathering, moisture, vibration, ozone, ultra-violet and temperature extremes. It will also resist various chemicals and oils depending on the chemical and duration of the contact.
