Applications & Uses

Cleaning Information

• Clean tools immediately after use.
• Once cured, the material can only be removed mechanically.
• Appropriate cleaners are listed in the product properties table. 

Usage Information

Processing	Suitable Substrates	Polycarbonate (PC)
		Polypropylene (PP)
	Consistency	Pasty
	Surface Requirements	Dry
		Clean
		Free of grease
		Free of dust
	Application Equipment	Two part mixing and metering system
