CHT Group Primer No. 6 Silicone Bonding Primer, Pint Bottle, Clear

Description

CHT Group Primer No. 6 is a clear silicone bonding primer supplied in a pint bottle. It is a complex solution of reactive silanes in a volatile solvent. After application the carrier solvent evaporates and leaves a thin layer that helps silicone elastomers adhere to prepared substrates, which makes the pint size convenient for smaller jobs, touch-up, and lab work.

Silicone Bonding Primer Benefits

• Reactive silane chemistry promotes adhesion between silicone and prepared substrates.
• Clear color leaves no added tint on finished, visible parts.
• Solvent flashes off to leave a bond-ready layer, often at relatively low temperature.
• Pint bottle suits low-volume bonding, sampling, and maintenance work.
• Backed by CHT Group silicone primer chemistry for repeatable results.

Apply a thin, even film to a clean, dry surface and let the solvent flash off fully before applying the silicone. Keep the coat light, since excess primer can leave a weak layer. The carrier is a flammable solvent, so keep the bottle closed, use adequate ventilation, and keep away from ignition sources. Run a small adhesion test before committing production parts.

Common Applications for This Silicone Bonding Primer

• Priming substrates before silicone bonding, potting, or sealing.
• Small-batch and touch-up work where a pint is the right quantity.
• Improving bond strength on parts exposed to moisture, vibration, or temperature swings.
• Lab and prototype work ahead of scaling up to larger primer packs.

Handling and Storage

• Store sealed, away from heat and ignition sources, within the labeled shelf life.
• Keep the primer dry, since moisture can shorten usable life once opened.
• Follow the safety data sheet for ventilation and personal protection.
• Test adhesion on representative parts before committing production.
