Robnor ResinLab is launching two new safety-focused resins, GR100 and GR200 are both non-hazardous and have hazard-free labelling.
“In recent years we’ve noted an increasing reticence towards hazardous chemicals and it was important for us to respond to this change,” Michael Buy, Technical Manager at Robnor ResinLab, explains. “Our customers are seeking safer, more environmental solutions, and with our new resins, GR100 and GR200, we can provide exactly that.”
Free from isocyanate or plasticiser, the new materials have been designed as an alternative option to polyurethanes, for applications such as potting, encapsulation and cable jointing.
GR100 and GR200 are said to be easy to mix and pour, and provide good electrical resistance and excellent water resistance – offering a quarter the absorption time over the same exposure time. With a cure temperature of 0°, the resins offer good low temperature flexibility, curing at a much lower point than many competing epoxies and polyurethanes. Post-cure, they 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. The products 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 with GR200 with a Shore classification of A30-35. Thanks to their flexible property, the cured material can always be cut or dug out, enabling access to the protected components and the ability to replace the materials if required.
Robnor ResinLab GR100 and GR200 can be purchased in bulk, as a twin pack or as a kit.
