black laboratory countertops epoxy resin material worktops anti-chemical

Advantages :
1. Safety: After SGS tested, ONUS products have no formaldehyde or any of noxious materials, it is safety for the user.
2. Heat Resistance : ONUS’s worktop can resist 262℃ , it won’t foam and crack, the fire can extinguish because it has no any of paper materials.
3. Mositure Resistance : Due to our products are monolithic, it won’t swell and distortion on the mositure area.
4. Reagents Resistance : ONUS’s product can resist many of chemical reagents, it won’t been corrode by the most of chemicals.
5. Durability : ONUS products are monolithic and non-porous, it cannot delaminate or swell
6. Molded : The molded marine edge is easy to clean and install for user, due to the smoothly and non-porous surface, it won’t hidden bacteria and guarantee the worktops have long life.
7. Repairability : All of our products are monolithic epoxy resin, if there are some scratches on the surface, it can repaired with the sand paper polishing.
