Abstract
Transparent, UV and heat resistant adhesive compositions and associated methods of manufacturing using such compositions are provided. Exemplary methods of use include the utilization of the provided adhesive compositions as part of tape to be used outdoors where UV exposure is high. The present invention also provides a simple one-pass calendering process whereby the UV resistant adhesive compositions may be formed and extruded directly onto tape backing.
Claims43
A UV and heat resistant pressure sensitive adhesive product having a backing layer and an adhesive layer adhered thereto, wherein the adhesive layer includes at least one polymer having a substantially saturated backbone and the polymer being heat and UV resistant and the adhesive being pressure sensitive.
A UV resistant adhesive tape comprising:
- a) an adhesive layer wherein the adhesive is transparent or translucent and wherein the adhesive includes at least about 50% EPDM;
- and
- b) a backing layer being transparent or translucent.
The method of manufacturing an adhesive tape comprising the step of extruding an adhesive composition extrudate at an interface between a bottom roll and a middle roll onto a preformed backing layer to form an adhesive tape.
The method of manufacturing an adhesive tape comprising the step of extruding an adhesive composition extrudate at an interface between a bottom roll and a middle roll onto a preformed backing layer to form an adhesive tape, wherein the adhesive layer is comprised of at least one polymer having a substantially saturated backbone.
The method of manufacturing an adhesive tape comprising the steps of:
- a) extruding a backing layer composition to a first nip between a top roll and a center roll to form a backing layer;
- b) feeding the backing layer to a second nip;
- c) extruding an adhesive composition at the second nip between the center roll and a bottom roll, such that an adhesive layer is applied on a surface of the backing layer to form an adhesive tape.
The method of manufacturing an adhesive tape comprising the steps of:
- a) extruding a backing layer composition to a first nip between a top roll and a center roll to form a backing layer;
- b) feeding the backing layer to a second nip;
- c) extruding an adhesive composition at the second nip between the center roll and a bottom roll, such that an adhesive layer is applied on a surface of the backing layer to form an adhesive tape, wherein the adhesive layer is comprised of at least one polymer having a substantially saturated backbone.
An article comprising:
- pressure sensitive adhesive comprised of at least one polymer having a substantially saturated backbone;
- a substrate upon which said pressure sensitive adhesive is disposed;
- and
- a second substrate disposed upon the pressure sensitive adhesive.
