1200 Series (Silicone Based Adhesives, Sealants and Potting Agents) แบรนด์ Threebond
These are single-component type silicone adhesives and sealants. They can be used for various purposes including bonding, sealing, and dampproof coatings for different fields such as for electric and electronic devices.
The curing reaction occurs from the moisture in the air when it is squeezed from the container, and it becomes a rubber-like elastic body.
They have a fast curing speed, the surface cures at room temperature and normal humidity (25°C / 50%RH) after ten minutes (tack free), and they reach a cured thickness of 1mm or greater after 2 to 3 hours.
The rubber elasticity of the cured material is maintained over a wide temperature range from -60°C to 250°C (approx.) (300°C for heat-resistant type). They have excellent adhesion, so they can bond to most materials.
There are two reaction types; the alcohol type (generates a small amount of methanol gas as a reactive byproduct) and the acetone type (generates acetone gas). Neither type is corrosive to metals such as electric-contact metals. They also do not dissolve or cause cracks on most plastics.
All grades of the 1220 Series are low-molecular siloxane-reduced products, so they do not cause electrical contact failures.
