IZOLEP-mastic — epoxy primer-enamel over rust and old coatings
Epoxy primer-enamel for bridges, pipelines and steel structures, applied over tight rust; C1–C5 and CX per GOST 34667.

PLAMCOR-4 belongs to structural fire protection: it is a dry mix based on Portland cement, expanded vermiculite and fibrous fillers, which is mixed with water and applied with SO-150-type plastering machines. The material is non-combustible and intended for heated and unheated premises with non-aggressive and slightly aggressive environments. An enamel is applied on top for decorative appearance and resistance to aggressive vapours and gases. Service life is at least 40 years in placement categories 3–4.
