Described herein are release layers formed via solventless extrusion. The release layers include a polyolefin and an alkyl dimethicone. The release layers exhibit tailorable release properties from pressure-sensitive adhesives. The release layers are simple to make and require no post-treatment in order to impart the observed release properties. The release layers are adaptable to multilayer extrusion, blown film formation, and cast film formation techniques.

摘要:
This invention relates to an ink-receptive composition, including: (a) a filler; (b) a binder having a Tg of less than 30° C.; and (c) a cationic polymer; wherein the composition, when coated on a substrate, forms an ink-receptive coating which accepts ink loading greater than about 300%. The coating compositions provide a printable surface receptive to high loading of ink-jet inks which do not crack at loading in excess of 300%, and in one embodiment, do not crack at loading up to about 400%. In addition, the print shows superior liquid resistance and the print quality of the inks is improved and a reduction in bleeding of colors occurs. Also, printed article have outdoor durability especially those with overlaminates.

A polyethylene molding material has a bimodal molecular weight distribution with an overall density of ≧0.948 g/cm3 and a melt flow index MFI190/5 of ≦0.2 dg/min. The molding material comprises from 35 to 65% by weight of low-molecular-weight ethylene hompolymer A having a viscosity number VNA in the range from 40 to 90 cm3/g, a melt flow index MFI190/2.16 A in the range from 40 to 2000 dg/min and a density dA of ≧0.965 g/cm3. Also included is from 35 to 65% by weight of high-molecular-weight ethylene copolymer B having a viscosity number VNB in the range from 500 to 2000 cm3/g, a melt flow index MFI190/5 B in the range from 0.02 to 0.2 dg/min and a density dB in the range from 0.922 to 0.944 g/cm3.
摘要:
The present invention relates to coated metal substrates such as metal piping having improved environmental stress crack resistance and resistance to hydrolytic and/or cathodic disbondment. The coating composition contains a blend of modified and unmodified polyolefins as well as a tackifier. For cathodic disbondment resistance, the preferred tackifiers are rosin esters or hydrogenated versions thereof. The modified polyolefins are grafted versions of metallocene or non-metallocene produced low density or high density polyethylenes.
