Data Sheet
PRIMER G718 and G718T
These primers are recommended especially for condensation curing RTV2 silicone rubbers. G718T has proved particularly useful for problems involving adhesion.
PRIMER G790
This primer is mainly recommended for addition curing RTV2 rubbers.
PROTECTIVE FILM SF18
Wacker protective film SF18 is used for covering surfaces of models or other surfaces with which the uncured silicone rubber makes direct contact. It is designed to prevent vulcanization problems (inhibition) of addition-curing RTV-2 silicone rubber at the contact surface.
COLOUR PASTES
ELASTOSIL® Pigment Pastes FL, are ready to use compounds consisting of pigments and reactive silicone polymer. Available in Yellow, Reddish Brown, Orange, Dark Red, Red Iron Oxide, Dark Blue, Light Blue, Green, Grey, Black, Deep Black and White.
THIXOTROPIC M
STABILIZER 43
Both additives are used to thicken or render non-sag those grades of ELASTOSIL® M “45..” and “M46..” high-strength series which are flowable as supplied.
Amber Composites offer these products as part of their Liquid Tooling Systems range.
