Description

RELEASE HT 100 is a synthetic polymer with high molecular weight in a 100% solid form. When in solution, it is a very efficient release agent for polyolefins and substrates with low melting point, coated with natural rubber, synthetic rubber and acrylic adhesives.
RELEASE HT 100 is produced by a particular polimerization tecnique that avoids heavy metals catalysts.
The product does not contain silicone compounds.

Application

RELEASE HT 100 can be used on corona treated as well as on untreated film. Concentrations range from 0.5% solid to 3% solids depending on film, coating equipment and desired release concentrations.
RELEASE HT 100 is soluble in aromatic and aliphatic solvents.
Solubility in toluene is fast, even at room temperature, while with other solvent blends (e.g. heptane/isopropyl alcohol at 3/1) it is necessary to heat the product at 40°C.
The good solubility of RELEASE HT 100 is due to its glasslike amorphous structure.

Technical Specifications

Handling

Slowly add RELEASE HT 100 to solvent and continuously stir. If necessary, heat at 40-50°C.
Be careful as the solvent is flammable.

Packing

Fiber drums with 25 kg plastic bags.

Storing

RELEASE HT 100 in 100% solid form can be stored safely at almost all normal temperatures below melting point. Shelf-life is 1 year. In solution, it must be stored at temperature not below 20-25°C to prevent gelification. In case of partial or total solidification, store the product in a heated place and stir it well before use. The product will become as fluid as before.
Do not coat if liquid is not completely clear or if solidification occurs.
Solution must be used with great caution, because of solvent presence (avoid inhalation, skin contact and flame presence).

Notes

Cloud point:

• 5% toluene solution: < 23°C
• 1% toluene solution: < 15°C
