SPMH - 091 Resin for Man-hole
SPMH - 091 Resin for Man-hole
SPMH-91 by Sagar Polymers is specially developed unsaturated polyester resin for manufacturing manholes, drain covers and related application, where easy high impact resistance, compressive strength and easy manufacturing is the prime requirement. Hand lay-up process can be used for its application. It has tendency to bear high compressive load over a long period of time and is weather and wear resistance.
Packing size: Plastic drum, tanker Gel-time and peak-temperature can be adjusted according to the requirement.
