Release K100 D

RELEASE K 100 D is a synthetic polymer with high molecular weight in a 100% solid powder form. When in solution, it is a very efficient release agent for polyolefins and substrates with low melting point (PE, PP, PVC, PET), coated with natural rubber, synthetic rubber and/or acrylic adhesives.

The product does not contain silicone components.

Product appearance: White to light yellowish fine powder. 

RELEASE K 100 D can be used on corona treated as well as on untreated films. Concentration of the solution prepared for the coating ranges from 0.3% to 2% solids, depending upon film coating equipment and desired release effect.
RELEASE K 100 D is soluble in aromatic and aliphatic solvents at temperatures above 35°C.
Recommended aromatic solvent is toluene, while for aliphatic solvents we recommend octane/ethanol or heptane/isopropyl alcohol 3 to1.
In order to achieve a continuous and homogenous coating, it is absolutely necessary that the temperature is kept above 35°C during the whole process.

Slowly add RELEASE K 100 D to solvent and stir continuously at a temperature between 35  and 50°C.
Handle with care, since the solvent is flammable.

The product is supplied in fibre drums (20 kg).

RELEASE K 100 D in 100% solid form can be stored safely at almost all temperatures 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 using. The product will return as fluid as before.
Do not coat if liquid is not completely clear or if gelification occured.

RELEASE K 100 D may be used as a release agent in adhesive sealing tape for indirect food-contact applications.
