Low-solvent or solvent-free adhesives
Short-term measurements after application of the release characteristics
Determination of volatile aldehydes. Part 3
1 Scope
This section GB/T 32371 specifies the low-solvent or solvent-free adhesives volatile aldehydes (especially formaldehyde and acetaldehyde) and
Determination of other carbonyl compounds content.
This section applies only to the low-solvent or solvent-free adhesive coated surface of the release was measured in the short term volatile aldehydes.
