DOST Strip System

PRODUCT DATA SHEET

Description:

DOST-Carbon Strip   is composite laminate strip made from epoxy impregnated fiber with unidirectional (linear) structure and standard dimensions.

Usage areas:

Post reinforcing of

         Tunnels, silos and bridges

         Parking structures

         Industrial buildings

         general construction buildings

Specifications:

Its application is so easy. It is sold being rolls of 100ms. It can be cut as needed by tin shears or spiral.

Preparation of floor:

Concrete should be sound and have enough strength for bonding. Surface should be cleaned and free of oil, dust, filth, protrusions or cavities, water and moisture. Weak concrete pieces should be broken and repaired by high strength repair mortar.

Application of material:

Epoxy paste is mixed proportionally, and applied on concrete prior to applying the strip. Abraded side of strip needs to be cleaned with acetone for removing any foreign debris and applied  by minimum thikness of epoxy paste. After waiting sufficient time for maximum adherence of epoxy, the strip needs to be applied to the surface uniformly.

Advantages:

         Very light

         Good high and low temperature properties

         Very thin so no increase on cross-section

         High Tensile modules and strength

         Good resistance against chemicals and moisture

         Very easy and quick installation

         Minimize the application errors

Caution:

Use of a particle mask is recommended for possible airborne particles. Gloves are recommended when handling strips to avoid skin irritation. Safety glasses are recommended to prevent eye irritation.
