SynthoGlass PPR-290 Two-Part Epoxy Primer

Description

SynthoGlass PPR-290 is a solvent-free, chemically resistant two-part epoxy primer used between epoxy filler compounds and SynthoGlass repair wraps. Provides high-build capability without sagging, and machinable once cured. Suitable for prolonged immersion and intermittent steam contact.

Benefits

• High-build, no slump or sag during application
• Re-coatable as soon as dry to the touch
• Broad chemical resistance: inorganic acids, alkalis, salts, organic media
• Machinable after full cure

Common Applications

• Primer layer between filler and composite repair wrap
• Field pipeline maintenance, marine and chemical-industry repairs
• Patch, plug, and leak-repair operations
• Geometric transitions over large defects prior to ECR installation

Surface Prep and Application

• Substrate at least 5 deg C (40 deg F) and at least 3 deg C above dew point
• Warm base component to 15.5-25 deg C before mixing
• Mix per kit instructions; over-coat within 3 hours
• Long-term immersion: up to 70 deg C (158 deg F); intermittent steam to 120 deg C
• Resistant to dry heat in excess of 200 deg C, load dependent
