Robnor ResinLab Launches Two Safety-focused Resins

Published on 2017-08-03. Author : SpecialChem

Robnor ResinLab has announced the launch of two safety-focused resins. The new resins are GR100 and GR200 and both are non-hazardous and have hazard free labelling. It makes them the safest resins as of now.

Safety-focused Resins

Reason Behind the Development

Technical Manager, Michael Buy, explains the driving force behind their development.

“In recent years we’ve noted an increasing reticence towards hazardous chemicals and it was important for us to respond to this change. Our customers are seeking safer, more environmental solutions, and with our new resins, GR100 and GR200, we can provide exactly that.”

Plasticizer- and Isocyanate-free

Free from Isocyanate or Plasticizer, GR100 and GR200 have been designed as an alternative option to polyurethanes, for applications such as potting, encapsulation and cable jointing.

Easy to mix and pour, GR100 and GR200 provide good electrical resistance and excellent water resistance – offering a quarter the absorption time over the same exposure time.

With a cure temperature of just 0˚, GR100 and GR200 offer good low temperature flexibility, curing at a much lower point than many competing epoxies and polyurethanes. Post-cure, the materials retain a slight stickiness, which may aid adhesion to certain substrates.

Both new products have fast gel and demold times – GR200 cures after only 1 hour while GR100 has a cure time of 3 hours. Furthermore, these materials have the additional benefit of curing without exotherm, meaning that curing is possible in thick or thin sections.

GR100 is the softer of the two materials with a hardness of A10, compared to GR200 with a shore classification of A30–35. Thanks to their flexible property, the cured material can always be cut or dug out, enabling easy access to the protected components and the ability to replace the materials if required.
