About Us

Greenchem Technology Pte Ltd was founded in 1997. GCT has been blending high-quality lubricants for automotive, industrial and marine purposes, incorporating the advanced formulae of US Technology, under the Ultra21 brand name.

The challenge ahead is to nurture this young but dynamic company onto greater heights of professionalism through dedication, commitment, flexibility and teamwork among its employees. In addition, GCT will also make relentless efforts to constantly improve and innovate its Ultra21 lubricants.

As a reflection of our commitment to quality excellence, we were awarded the PSB ISO 9001 certificate on 7th May 2002. In line with global trends towards environmental conservation, part of the company's quality policy reflects its vision for a greener tomorrow, not forgetting its commitment to its customers through tenacity among its employees.
