BLUESIL ADD 916 is added to HCR’s on a 2-roll mill.
The normal dosage is 0.5 % by weight with respect to the HCR pre-catalysed compound.
Higher doses are not necessary and may even have a detrimental effect on the heat stability of cured compounds.
Comments: BLUESIL ADD 916 tends to make transparent mixtures opaque.
Improving the compression set of MF 135 U and MF 175 U by adding BLUESIL ADD 916:
For example, the table below gives the change in mechanical properties for MF 135 U and MF 175 U with and without the addition of BLUESIL ADD 916.
These properties are obtained after adding 2-4 dichloro benzoyl peroxide with 50 % active ingredients (Peroxide E) and curing for 8 minutes at.

BLUESIL ADD 916 is an acid acceptor that improve the compression set of HCR’s cured with 2-4 dichloro benzoyl peroxide (especially for hot air curing), without post-curing.
BLUESIL ADD 916 avoids efflorescence (blooming) of non post-cured, vulcanised compounds.
