SILCOR® Primer BW N105-DT
General purpose, solvent-free epoxy primer
Product Description
A two-component, solvent-free epoxy primer, recommended for use with concrete, masonry and steel.
Features
- Fast-cure
- 100% solid content
- Excellent penetration and adhesion to substrate
- Simple and easy application, high build self leveling
- Good bonding with concrete, sound masonry and steel. Also bonds to damp concrete. Recommended moisture content is <5% based on ASTM F2659.
Application
The surfaces of new concrete should be lightly blast abraded or mechanically abraded to remove laitance. Dust and debris created from blasting or sanding should be removed by sweeping or vacuum cleaner. Surface must be clean, sound, smooth and free from dust, laitance, loose matter, oil or other contaminants.
Pour the hardener into the resin and mix thoroughly for 5 minutes until the colour is uniform using a low speed drill at 200 to 300 rpm. Do not mix more than is required because the material will gel and harden.Heat is generated when the resin and hardener reacts and temperatures will increase over time. Apply soon after mixing. Never mix more than one batch at a time in a single container as this may cause a premature exothermic reaction with production of intense heat and smoke.
Apply SILCOR® Primer BW N105-DT by brush, roller or rubber squeegee. Application temperatures must be between 10°C and 40°C with <85% relative humidity, and at least 3°C above the dew-point temperature.
Coverage
Generally 0.2-0.5kg/m2 dependent on substrate condition, application technique and weather.
More is required for porous concrete.
