LOCTITE PC 7227
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Ultra-Smooth Brushable Ceramic Coating
- 92 um Vertical Sag Resistance
- 100 deg C Dry Service
Product Description
LOCTITE PC 7227 is a solvent-free, two-part brushable epoxy reinforced with ceramic for wear and corrosion protection on industrial equipment. Part A and Part B mix at 2.75:1 by volume or 4.8:1 by weight, with an application temperature of 20 to 30 deg C. Typical mixed properties at 25 deg C include 1.4 g/cm^3 density, 20,000 mPa s cone-and-plate viscosity at a 10 s^-1 shear rate, and 92 um vertical sag resistance by ISO 16862. After seven days at 22 deg C, typical cured properties include Shore D 85 hardness, 27.3 N/mm^2 tensile strength, and 7.57 kV/mm dielectric strength. Typical service temperatures are 100 deg C dry and 90 deg C wet.
Key features
