Principal Applications
Fast curing primer for new and existing metal surfaces, prior to the application of Silcor elastomeric waterproof membranes.
- Glazing channels
- Drainage outlets
- Column bases
- Cladding upstands
- Other steel surfaces
Note: Metal surfaces other than steel will require different surface preparation. Contact GCP for further details.
Installation
1. Surface Preparation
- Metal surfaces must be sound and clean. Remove all contaminants such as scale, rust, dirt, oils before application of the primer. Clean and sand blast the surface to near white finish (SA 2½) prior to application of the primer. Do not sand scatter and protect from sand scatter contamination.
- The surface needs to be dry before application of Silcor Primer MT.
2. Mixing
- Mix each component before mixing them together.
- Mix complete sets. Do not use part mixes.
- Mix well with a slow speed mixer (300 rpm) for 3 minutes untill a homogenous mix is obtained.
- Mixing temperatures should be 5 to 30°C. Higher temperatures reduce the pot life considerably.
- Pot life at 20°C is 8 hours.
3. Application
- Assure sufficient ventilation during application of Silcor Primer MT.
- Apply Silcor Primer MT by brush, roller or airless spray. Distribute evenly over the surface to obtain uniform coverage. It is recommended when spray applying the primer to subsequently roll it down onto the surface to assure complete and uniform coverage.
- Typical consumption: 150 g/m².
- Do not apply Silcor Primer MT when the ambient temperatures are below 5°C or expected to drop below this temperature. Maximum application temperature 30°C.
- Recommended maximum application delay after sandblasting steel to prevent flash rust are:
1 hour at a relative air humidity of 90%.
2 hours at a relative air humidity of 85%.
4 hours at a relative air humidity of 80%.
10 hours at a relative air humidity of 70%.
24 hours at a relative air humidity of 60%.
Unlimited at a relative air humidity below 40%.
4. Curing
Curing times at 20°C
Hand dry: 4 hours.
Maximum recoat time: 12 hours.
5. Cleaning and maintenance
- Clean all tools with solvent. Hardened material needs to be removed mechanically.
Product Advantages
- Excellent adhesion to metal surfaces.
- Prevents ‘flash’ rust formation.
- Fast curing.
- BBA Certificate.
- European technical approval.
