OTTO Cleanprimer 1101 bonding cleaner for metal and plastic

Description

OTTO Cleanprimer 1101 is an adhesion cleaner based on a solvent-based cleaner with adhesion promoter for coated and uncoated metallic materials and various plastics such as PVC. It cleans the bonding surfaces and improves the adhesion of OTTO sealants and adhesives in one operation. The 100 ml aluminium bottle is enough for individual joints and minor repairs.

Benefits at a glance

  • Two steps in one: cleans the bonding surface and at the same time improves the adhesion of the sealant or adhesive.
  • No waiting time: no flash-off time required, the sealant can be applied directly afterwards.
  • High yield: consumption approx. 30 to 50 g/m², depending on the absorbency of the substrate.
  • Toluene-free: formulated without toluene according to the technical data sheet.
  • System-tested: Compatibility with OTTO sealants and adhesives tested and approved by OTTO application technology.

Areas of application

  • Uncoated metallic materials
  • Coated metals
  • PVC and other plastics
  • Joint flanks before applying OTTO sealants

Limits & notes

The Cleanprimer is intended for metals and plastics. For porous, mineral substrates such as concrete or plaster there are separate OTTO mineral primers. For combinations other than with OTTO sealants and adhesives, OTTO recommends preliminary tests. Do not apply the primer beyond the joint edges and bonding surfaces, otherwise soiling or visual changes are possible.

Application & tips

Free the bonding surfaces of release agents, grease, oil, dust, water and old adhesives or sealants; clean non-porous substrates with OTTO Cleaner T and a clean, lint-free cloth, clean porous substrates of loose particles mechanically, for example with a steel brush or grinding disc. Apply the Cleanprimer with a clean rag and sufficient pressure so that it cleans well. A drying time is not required; further processing can also take place several hours later, provided no dust gets onto the surface. Solvent-containing, flammable: only with good ventilation, away from ignition sources; wear safety goggles and solvent-resistant gloves, according to the safety data sheet made of butyl rubber with a thickness of more than 0.4 mm. Because of the many influences on site, a trial application is always necessary. The use-by date is on the container, storage stability is 12 months at 23 °C.
