Epoxy resins
They usually have a higher temperature performance than polyurethanes, shrink less while hardening, are harder and stronger, and can be made more flame-retardant. They provide a better adhesion, are more resistant to humidity during and after the hardening as well as to chemicals.
Polyurethanes
In comparison with epoxy resins, they are generally softer, more flexible and really elastomeric and therefore they cause a reduced load of the protected components. They offer a much faster hardening at low temperatures, have a much better resistance to abrasion and a lower operating temperature (up to -60°C).
Packaging
Bag
Two-component packaging containing resin and hardener in the correct ratio in a plastic bag.
Kits
Resin and hardener in the correct ratio are delivered in two containers.
Large quantities
Resin and hardener are delivered in separate containers and must be mixed together in the correct ratio.
