Release K 100 S

1 of 75 products in this brand
RELEASE K 100 S 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 is not recommended for hot-melt pressure sensitive adhesives. Thanks to its excellent solubility it is particularly suitable for printing applications (BOPP packaging tapes, PE protective films, etc). RELEASE K100 S is also recommened for the coextrusion of PE and PP films, where a constant release effect over the complete surface can be obtained. The product is silicone free.

Applications & Uses

Applications

RELEASE K 100 S can be used on corona treated as well as on untreated films.
Concentration ranges from 0.3% solid to 2% solids, depending upon film, type, coating equipment and desired release force.
RELEASE K 100 S is soluble in aromatic and aliphatic solvents at temperatures above 35°C. In order to achieve a continuous and homogenous coating, the RELEASE K 100 S must be completely dissolved and the solution must be clear and homogeneous. If used in coextrusion process,
RELEASE K 100 S must be compounded at 4-5% to the polymer (PE or PP). This masterbatch has to be coextruded in a layer as thin as possible.

Storage & Handling

Handling

Slowly add RELEASE K 100 S 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.

Storing

RELEASE K 100 S 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.
