PARSON ADHESIVES, INC
|
PARFIX Cyanoacrylate adhesives offers a major advantage over other type of adhesive systems.
They are a single component adhesives, fast curing at room temperature, solvent free and resistant to many environmental factors.
Cyanoacrylates are based on a wide range of different acetates with the smallest molecule size being methyl followed by ethyl and then the larger size such as butyl etc.
In general the smaller the molecule the greater the overall strength and faster the speed of cure.
The main advantage of the higher molecular weight ester is less odor, reduced 'blooming' and slightly more flexibility.

The above should use as guide, some grades perform
better when used to bond different materials such as metal to rubber, other
have better shelf life under difficult conditions. |
