Epoxy Bonding Adhesive
CPR 702 – Epoxy Bonding Adhesive is a thixotropic, solvent free Epoxy adhesive ideal for bonding a wide range of building materials to one another e.g. concrete, brick, metal, stone and wood. CPR 702 – Epoxy Bonding Adhesive has a high level of mechanical integrity and exhibits excellent bonding characteristics even under damp conditions. CPR 702 – Epoxy Bonding Adhesive is easy to mix and apply and requires no primer.
- Colour coded components to ensure correct mixing
- Excellent adhesion to most building materials
- Bonds to damp substrates
- Low odour
- Thixotropic nature facilitates application in both vertical and overhead locations
- Very good chemical properties and cohesive strength
- Resistant to water, weathering and a wide range of chemicals
- No primer required
- Creep resistant
Directions for Use
- Concrete substrates shall be sound, clean and free from dust, dirt, grease, oils, laitance and other contaminants.
- A roughened or profiled surface will ensure optimum adhesion.
- Mild steel and other metallic substrates shall be degreased, power wire brushed or grit blasted and vacuumed free from dust.
- Other substrates shall be sound, clean and free from dust, dirt, grease, oil and any oxidised surface layer.
- The Base and Curing Agent components shall be thoroughly mixed together using a stiff spatula or a slow speed drill with paddle attachment until a uniform grey mixture has been produced.
- The application of CPR 702 – Epoxy Bonding Adhesive is best achieved using a spatula, trowel, serrated trowel or stiff bristled brush depending on the area to be treated.
Bonding Surfaces Together
- CPR 702 – Epoxy Bonding Adhesive shall be applied to each of the two surfaces to be bonded.
- The surfaces are then pushed together to achieve the required bond thickness.
- Excess adhesive should be removed and the joint protected from movement until the resin has set.
- Scrape or ‘knife in’ the CPR 702 – Epoxy Bonding Adhesive and finish with trowel, palette knife or spatula.
- Note: For more inaccessible areas, CPR 702 – Epoxy Bonding Adhesive may be placed into empty cartridges and injected/‘gunned’ into place using a standard sealant gun.
- Clean equipment with CPR 201 Tool Clean Solvent prior to curing of the coating.
- CPR 702 – Epoxy Bonding Adhesive will be hard dry following 10-12 hours cure @ 20°C.
- At higher temperatures this period will be reduced and at lower temperatures this period will be increased.
- Allow 7 days for optimum mechanical properties and full chemical resistance.
