Applications & Uses

Processing

Processing	Preparation of Adhesive	Adhesive must be stirred to homogeneity before use
	Consistency	Pourable
	Surface Requirements	Dry
		Clean
		Free of grease
		Free of dust
		Polyolefin plastics have to be corona or flame treated
		Other plastics and metals should be primed
	Application Method	Roller coating
		via two part mixing and metering systems potting
Cleaning	Cleaner for Tools	Körasolv PU
Hints	Moisture Sensitivity	The adhesive must not be exposed to moisture before and during application. Moisture causes foaming leading to lower mechanical properties.

• Preparation: For some substrates the use of mechanical pretreatment and/or cleaner or primer is necessary to achieve good adhesion.
• Processing: Low temperatures can cause a temporary increase in viscosity resulting in reduced extrusion and slower curing rates.
• Cleaning: Clean tools immediately after use. Once cured, the material can only be removed mechanically.
