Scotchkote™ Abrasion Resistant Epoxy Coating 328, by 3M

Description

3M™ Scotchkote™ Abrasion Resistant Epoxy Coating (AREC) 328 is a 100% solids, two-part epoxy system designed for directional drilling, rocky terrain, or other applications that require a rugged coating. Combining a traditional liquid epoxy with enhanced impact resistance, gouge resistance, and flexibility, an AREC coating can be used in place of a conventional Abrasion Resistant Overcoat (ARO). With strong adhesion to both metal and FBE, it is equally effective for use as a primary corrosion protection coating for applications which require high flexibility after cure, in which long-term adhesion is critical. Best of all, Scotchkote coating shows that abrasion resistant coatings can be easy to apply!

More Rugged than Traditional Epoxy Coatings

• Increased Abrasion Resistance, Impact Resistance, Gouge Resistance and Flexibility
• Provides rugged protection at 20-30 mil instead of 40-70 mil

Improved Performance Over Traditional Liquid Epoxies

• Improved adhesion to steel and FBE
• Improved Cathodic Disbondment Resistance

Easier to Apply than some Abrasion Resistant Overcoat (ARO) products

• Applied by plural component spray equipment, brush or roller
• High build up to 45 mils / 1150 microns in one pass
• Lower viscosity = easier to work with
• Can be applied to substrate at temperatures down to 41°F/5°C

Multiple Coats (Recoat Window)

Scotchkote coating 328 has been formulated to achieve a coating thickness of 45 mils/1150 microns in one application. If additional thickness is required then it is to be applied within the following time in table below. If the time is exceeded then abrade existing coating by brush blast or coarse sand paper before applying second coat.
