Abstract
Protection against impact damage to delicate items stored in a protective encasement such as cell phone cases is significantly improved by protectively lining the interior of a protective encasement with a unique protective combination. This combination includes a protective inlay or insert of a thermoset viscoelastomeric protector in its static form coated with a compatible and non-confining elastomeric polymer coating. Coating the viscoelastomeric protector with the elastomeric coating necessarily requires retention of an undistorted viscoelastomeric protector in its static form during the formative coating procedure. This can be effectively accomplished by injecting coating under low pressure and high solids coating conditions.
Claims23
A protective encasement combination for protecting a stored item against damage caused by an impacting force, said combination comprising:
- A. an encasement for storing items therewithin;
- B. a thermoset viscoelastomeric inlay in a static form positioned within the encasement so as to provide impact damage protection to a stored item against the impacting force;
- and
- C. an elastomeric coating overcoating the thermoset viscoelastomeric inlay so as to provide an elastomeric coated inlay;
- wherein the thermoset viscoelastomeric inlay comprises a cured thermoset reaction product of a reaction media comprising an epoxidized vegetable oil as a predominant reactant by weight, about 20 to about 40 percent by weight of a polyether triol, about 6 to about 12 percent by weight of a polyether diol, about 5 to about 8 percent by weight of a methylene diphenyl isocyanate-based polyether prepolymer, and about 0 to about 10 percent by weight of a bleached vegetable oil;
- and
- wherein the reaction media has been reacted in the presence of a catalytic amount of a thermosetting catalyst.
A method for making a protective encasement combination for protecting stored items against an impacting force, said method comprising:
- A. selecting an encasement for a stored item;
- B. providing a cured thermoset viscoelastomeric protector in a static form having impacting force arresting properties, wherein the thermoset viscoelastomeric protector is prepared by curing a thermosetting reaction media comprising an epoxidized vegetable oil as a predominant reactant by weight of the thermosetting reaction media, about 20 to about 40 percent by weight of a polyether triol, about 6 to about 12 percent by weight of a polyether diol, about 5 to about 8 percent by weight of a methylene diphenyl isocyanate-based polyether prepolymer, and about 0 to about 10 percent by weight of a bleached vegetable oil, wherein said thermosetting reaction media is reacted in the presence of a catalytic amount of a thermosetting catalyst, and wherein the thermoset viscoelastomeric protector is disposed within an internal cavity region of the encasement;
- and
- C. surface coating the thermoset viscoelastomeric protector with an elastomeric polymer coating, wherein said surface coating is conducted under coating conditions which substantially retain the static form of the thermoset viscoelastomeric protector.
