AS1623
1 part low corrosive self levelling high temperature adhesive sealant
Introduction
AS1623 is a fast cure 1-part RTV silicone sealant specially
formulated for applications requiring a combination of good
adhesion, excellent physical and non-corrosive properties. The
Oxime based cure system produces excellent physical properties
and good adhesion particularly to plastics and many other
substrates. Although not totally neutral the cured sealant is very
low corrosive in nature.
Key Features
High temperature 260°C continuous
High temperature 315°C intermittent
Excellent flow and self - levelling characteristics
Primerless adhesion to many substrates
Use and Cure Information
How to Use
AS1623 is ready for use. If supplied in cartridges it can be applied
using either manual or pneumatic dispensers.
It can also be applied from bulk containers using conventional
drum dispensing equipment.
Application and Cure
All surfaces to which AS1623 is to be applied should be clean, dry
and free from grease, dirt, and loose material.
Priming of surfaces is not normally required.
If it is being employed as an adhesive, it should be applied to one
clean surface and the other clean surface brought into contact with
it within 30 to 60 seconds.
The recommended thickness of the sealant joint is
1 to 3mm for optimum bond strength.
Joints should be left undisturbed for at least 24 hours, but
preferably longer to effect sufficient depth of cure. Full cure
requires 7 days.
