Keytec MRC 1500

Reinforced Chemical Resistant Membrane

What is MRC1500?

MRC1500 is a synthetic reinforced membrane based on a polyester textile which is molecularly coatedwith a high quality resin. The polyester tissue gives high mechanical properties to the membrane while the coating provides the waterproofing and chemical resistance. The tissue consists of polyester threads. The polyester tissue is firstly impregnated with a resin to avoid all wicking effects; then the tissues are coated with a resin. This resin is an “interethylene polymer resin” which provides the membrane with a high resistance against petroleum products and other chemicals. MRC1500 membrane is very flexible and has a high dimensional stability.

Suggested specification
