  • Patent number: 8765263
    Abstract: A multilayer protective film comprising a first layer, a second layer and a PSA layer. The first layer at least comprises a polyester-based polyurethane, a polycarbonate-based polyurethane or a combination or blend of both. The second layer at least comprises a polycaprolactone-based thermoplastic polyurethane. The PSA layer comprises a pressure sensitive adhesive. One major surface of the first layer is bonded to one major surface of the second layer, and the PSA layer is bonded to an opposite major surface of the second layer such that the second layer is sandwiched between the first layer and the PSA layer.

  • Patent number: 8551285
    Abstract: A method of making a multilayer protective film. The method comprises: (a) forming a PU layer comprising an at least partially crosslinked polyurethane, the at least partially crosslinked polyurethane comprising at least one of a polyester-based polyurethane or a polycarbonate-based polyurethane; (b) forming a TPU layer comprising a polycaprolactone-based thermoplastic polyurethane; (c) forming a PSA layer comprising a pressure sensitive adhesive; (d) bonding one major surface of the PU layer to one major surface of the TPU layer; and (e) bonding the PSA layer to an opposite major surface of the TPU layer; wherein the TPU layer is sandwiched between the PU layer and the PSA layer. The multilayer film may be used to protect painted surfaces of vehicle body parts.

  • Publication number: 20130034694
    Abstract: A translucent surface protection film suitable for protecting relatively rough surfaces such as, for example, the painted surfaces often found on architectural structures like doors, walls, etc. The translucent surface protection film comprises a polymeric layer backed by an adhesive layer comprising a pressure sensitive adhesive. The adhesive layer defines a major surface of the film, with another major surface of the film having a surface texture that exhibits a 60 degree Gloss Level of less than or equal to 15. The rheological properties of the adhesive allow the adhesive layer to achieve a wet out of at least 70%, when the adhesive layer is applied onto a surface having a surface roughness with a peak count (PC) of at least 250 peaks/meter.
