DESCRIPTION
Laprolin Extra RUS pH 14 – Russian, innovative, synthetic non-combustible material of the new generation, developed by the team of SPE “Special Materials”.
This material is designed for protection against corrosion and damage of various metal, concrete, brick, wooden structures and bases.
WIDELY USED:
- in civil construction for protection of metal and concrete structures, bridges and their pillars, flumes, water treatment facilities, water canals. In combination with loose materials it is used as a repair composition for all types of concrete articles (bridges, pillars, piles, ramps, flights of stairs, concrete floors), as well as a polymer topcoat with various color schemes.
- in the industry for protection of the surface of off-shore oil platforms, pipelines, oil derricks and reservoirs, as well as a protective coating for ships, submarines, motorboats and other machinery
Applications in detail
Anticorrosive and sealing material LAPROLIN EXTRA RUS pH 14, is a homogeneous sticky mass of light-yellow to light-brown color, manufactured of polyether becoming hard at a temperature from - 30°C to + 50°С.

APPLICATION TEMPERATURE:
This material is used in various climatic conditions (from -70°C to +130°C, and up to 6-8 hours – max. 190°С). It can stand contact with aggressive media (from pH 0 to pH 14, from sweet water to see water, from alkali to acids, from crude oil to petroleum products). It is allowed to use the material at temperatures below zero, down to -15°C and over a wide humidity range from 25 to 85%.

APPLICATION INSTRUCTIONS
The material is applied to the prepared processed surface: with rollers, brushes, airless spraying with a nozzle 0,019”- 0,023”. Filled composition is applied by airless spraying with a nozzle 0,014” - 0,017”. It is allowed to use the material at temperatures below zero, down to -15°C and over a wide humidity range from 25 to 85%. When applying the material to the surface avoid contact with moisture.
MATERIAL APPLICATION TECHNOLOGY:
- Remove buildups or the loose layer (scale, rust, dust, loose concrete, etc.) manually, mechanically or by sand blasting;
- Clean application surface of dust;
- Degrease the application surface, 5% alkali solution (as appropriate), waiting time 10 minutes;
- Primer application, waiting time 1 hour;
