5 VERSIONS
Available in white version reference Norester® 976 PA White with a gel time of 11 -15 min (20°C - 2% MEKP on 100
g).
6 RECOMMENDATIONS BEFORE USE
During storage, a settling low of the charge may appear. Mix the product thoroughly before use so as to have a
homogeneous mixture.
Before use, check that the temperature of the product, the mould and the room is between 18°C and 25°C.
For NPA version, take care not to mix the accelerator and the peroxide together but add them seperatly in the
resin.
Mix the peroxide well, never put under 1% or over 2%
We recommend to add 2% of MEKP peroxide in the resin.
We retain the attention on the fact that the Norester® 976 is classified according to the certificates named
above and tested on applications produced in our laboratory. It is the responsibility of the customer to assure
that the parts he produces are well classified.
7 POST CURING
To obtain optimum resistance properties, the laminate with the Norester® 976 must be post-curing. In order to
accelerate the hardening, the laminate stays at ambient temperature (16 à 20 °C) during 24 hours followed a postcuring of 16 hours at 40°C. We advise to do a post-curing immediately after ripening period to obtain optimums
results.
8 PACKAGING
Available in cans of 25 Kg and drums of 250 Kg.
9 STORAGE CONDITIONS AND HANDLING
Storage life: NORESTER® 976 resin is stable for 3 months from date of production. The product must be stored in
