Description
CONAP AD-1146-C Adhesive Primer 1 Gallon is a solvent-borne primer used when liquid polyurethanes need dependable adhesion to metal, glass, laminates, wood, or leather during the curing process. AD-1146-C primer is the amber low-viscosity version in the AD-1146 family, supplied here in a one gallon container for production, tooling, and larger prep runs.
AD-1146-C primer Benefits
- Low 125 to 225 cP viscosity supports brushing, spraying, roller coating, or doctor blade application.
- Gallon packaging suits repeat production instead of small repair-only prep work.
- Recommended for aluminum alloys, magnesium, iron, steel, glass, glass-fiber laminates, wood, and leather.
- Two-coat process gives buyers a clear, repeatable application path for this grade.
- Can be thinned with CONAP S-1 solvent for spray work when needed.
ELANTAS positions this primer for bonding liquid polyurethanes to a wide variety of substrates, and the technical sheet gives detailed cure guidance rather than vague prep notes. That is helpful for engineers and maintenance teams that need to document surface prep, solvent flash-off, and heat activation before urethane casting or bonding moves into the mold or assembly step.
Common Applications for AD-1146-C primer
- Preparing metal parts before polyurethane bonding or casting.
- Glass and glass-fiber laminate surface prep in electrical and engineering builds.
- Wood and leather details when the approved process calls for polyurethane bonding.
- Production cells that need a gallon size for repeated coating and heat activation cycles.
Compatible Materials
- Aluminum alloys, magnesium, iron, and steel.
- Glass and glass-fiber laminates.
- Wood and leather.
- Liquid polyurethane bonding processes.
