LOCTITE PC 7277 - 5kg (epoxy resin for concrete corrosion protection, blue)
Product description:
LOCTITE PC 7277 is a solvent-free two part epoxy coating. It is designed for the protection of concrete surfaces subjected to corrosive environments. It has high chemical resistance, so it can be exposed to solvents and a wide variety of weak and concentrated acids and bases. Further information about the product: biuro@woronko-kleje.pl
Steps to achieve the best adhesive results:
Surface Preparation
Proper surface preparation is critical to the long-term performance of this product. The exact requirements vary with the severity of the application, expected service life, and initial substrate conditions.
● Concrete must be cured for at least 30 days.
● Remove all grease, oil and dirt by washing thoroughly.
● Surface contaminants such as old coating, loose concrete and dust should be removed by dry abrasive blasting, water blasting, scarifying or by acid etching and thoroughly rinsing.
● Prepared surface must be rough with no excess water. Surface profile CSP3 to CSP5 (ICRI - standard guideline 03732).
● All surface irregularities, joints, holes, pores, and cracks must be filled.
Application
● Best results will be obtained when coating area is protected from direct sunlight and sudden temperature changes.
● Ambient and substrate temperature range: 15 to 40 °C.
● Relative humidity: <85 %; substrate temperature must always be 3 °C higher than the dew point.
● Concrete may outgas due to its surface porosity. In order to minimize this effect, the coating should be applied when the temperature of the concrete is going down, i.e, in the evening.
● Add contents of container B into container A. Mix thoroughly until color is consistent. Ensure material temperature is between 15 and 30°C.
● Brush or roll a coating layer thickness of 200 to 300 microns.
Storage:
Store product in the unopened container in a dry location. Material removed from containers may be contaminated during use. Do not return liquid to original container. Storage information may be indicated on the product container labeling. Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties. Henkel cannot assume responsibility for product which has been contaminated or stored under conditions other than those recommended.
