Paraloid B-72 and Tinuvin

In the Conservation Center I am working (CREA), we are discussing
the use of stabilizers as Tinuvin 292, 1130 and 327

The specific question for you is: we are working in the conservation
of a 300 painting collection of Museo Municipal de Valparamso. We
have just finished the first stage of this project that included the
conservation of 30 European and Chilean easel paintings from the XIX
century. We have the inconvenient that the Museum that will hold
this collection does not have controlled lighting conditions or UV
filters in the windows due to lack of funding.

We have some doubts regarding the choice of a top coat varnish. A
first coat of Dammar varnish has already being applied without any
additive and Paraloid B-72 with a percentage of Cosmoloid (to lower
the gloss) as a final coat.

As a Scientific Laboratory Director I would like to know if it is
possible the use of a top coat of Paraloid B-72 with some of the
Tinuvin additives to avoid the deterioration and yellowing of the
Dammar layer already applied. What would be your opinion and advice?
