Description
RELEASE KF 100 is a synthetic polymer with high molecular weight in 100% solid powder form. When in solution, it is a very efficient release agent for polyolefins and substrates with low melting points (PE, PP, PVC, PET), coated with natural rubber, synthetic rubber and/or acrylic adhesives. It can also be used with hot-melt pressure sensitive adhesives, if the chilling roll is well cooled. The product is silicone-free.
Application
RELEASE KF 100 can be used on corona treated as well as on untreated films. Recommended concentration ranges from 0.3% to 2% solids, depending upon film, type, coating equipment and desired release force. RELEASE KF 100 is soluble in toluene and octane/isopropanol (70/30) at 2% concentration at temperatures above 30°C.
In order to achieve a continuous and homogenous coating, the RELEASE KF100 must be completely dissolved and the solution must be clear and homogeneous.

Handling
Slowly add RELEASE KF 100 to the solvent and stir continuously at a temperature between 35 and 50°C till complete dissolution of the powder.
Handle with care, since the solvent is flammable.
Before coating, it is recommended to stir and heat the solution at 30°C at least.
Packaging
The product is supplied in fibre drums (20 kg).
Storing
RELEASE KF 100 in 100% solid form can be stored safely at any temperature below its melting point. In solution, it must be stored at temperatures not below 25°C to prevent gelification. In case of partial or total solidification, store the product in a heated place and stir it well at a temperature between 35°C to 50°C before use. The product will return as fluid as before.
Do not coat if liquid is not completely clear or if gelification occured.
