Represent products of interaction of the polymerized fatty acids of vegetable oils and polietilenpoliamin. Are applied to "cold" and "hot" hardening of epoxies, and also as the plasticizing agents of epoxies at production of the filling compounds, glues binding for fibreglasses, paint and varnish and other materials. Provide to the cured products good resistance to aromatic and aliphatic solvents, fuel, oils, water, solutions of salts, and also – to seasonal differences of temperatures. Have the increased adhesion and elasticity which can be regulated, changing a ratio "epoxy pitch / hardener". Malotoksichna. Are convenient in use because of smaller sensitivity to a ratio "epoxy pitch / hardener".
PO - 300M has a number of advantages in comparison with aminny hardeners: allows to receive compositions with the best elastichesky properties, bigger viability, rather small shrinkage.
These coverings surpass the coverings cured by amines in adhesion and gloss. Epoxy and polyamide structures surpass the coverings cured by amines in light resistance and thermal stability.
On the basis of polyamide PO - 300M pitch release: hardener No. 5.
Physical and chemical properties of PO - 300M pitch correspond to a hardener of Versamid - 125
Viability with basic pitch (EEW=190) ~ 5 - 6 hours at 20 ° C.
The mass of the hardener used in various areas of the equipment for 100 g of ED - 20 epoxy (21% of the EDS. groups), in an interval: 60 – 100 g.
The recommended hardening modes:
1. The standard mode of 36 - 48 hours at (20 - 25) °C Or 1 - 2 hours at 65 °C
2. The mode applied to giving
the improved physicomechanical characteristics to products of 6 hours at 40 °C of + 6 hours at 100 °C
The exact quantity of a hardener and viability of composition is defined by the consumer experimentally depending on a scope, a lot of filling, the mode of hardening, existence and a type of a filler etc. ;
Warranty period of storage – 1 year.
