Non-hazardous resins are safe

Robnor ResinLab has just announced two safety-focused resins. The GR100 and GR200 are both non-hazardous and have hazard free labelling and, according to the company, they are the safest resins ever manufactured by the formulator. Free from Isocyanate or Plasticiser, Robnor ResinLab materials GR100 and GR200 have been designed as an alternative option to polyurethanes for applications such as potting, encapsulation and cable jointing.

Said to be 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 demould 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.
