Abstract
A novel process for ensuring adequate adhesion between a ketone ethylene ether (KEE) and liquid polyvinyl chloride (PVC) roofing membrane and rubberized tape. The process can be used for roofing membrane repair, maintenance, and reinforcement. The present process uses a plasticizer primer comprising phthalate to coat the KEE/PVC roofing membrane, which has been shown to improve the adhesion to rubberized tape, allowing for good adhesion and increasing the lifespan of the repair, maintenance, and reinforcements.
Claims38
A process for providing adhesion between a ketone ethylene ether (KEE) and liquid plasticizer polyvinyl chloride (PVC) roofing membrane and rubberized tape comprising:
- a) preparing a PVC plasticizer primer comprising a phthalate;
- b) coating a KEE/PVC roofing membrane patch or a portion of a KEE/PVC roofing membrane with said plasticized primer;
- and
- c) adhering rubberized tape to the coated area of the KEE/PVC roofing membrane or patch.
A process for repairing a damaged KEE/PVC roofing membrane using a KEE/PVC roofing patch and rubberized tape comprising:
- a) preparing a plasticized primer comprising phthalate;
- b) identifying a damaged area of a KEE/PVC roofing membrane;
- c) coating an area around said damaged area of the KEE/PVC roofing membrane with said plasticized primer;
- d) adhering rubberized tape to said coated area;
- e) sourcing a KEE/PVC roofing patch large enough to cover said coated area of the KEE/PVC roofing membrane;
- f) coating said KEE/PVC roofing patch with said plasticized primer;
- and
- g) laying said KEE/PVC roofing patch over said coated area such that that the KEE/PVC roofing patch fully contacts said rubberized tape and covers the said coated area.
A process for reinforcing an area around an element protruding through a KEE/PVC roofing membrane using a KEE/PVC roofing patch and rubberized tape comprising:
- a) preparing a plasticizer primer comprising a phthalate;
- b) identifying an element protruding though a KEE/PVC roofing membrane;
- c) coating an area around said protruding element with said plasticized primer;
- d) adhering rubberized tape to said coated area;
- e) sourcing a KEE/PVC roofing patch large enough to cover said coated area of the KEE/PVC roofing membrane;
- f) coating said KEE/PVC roofing patch with said plasticized primer;
- and
- g) laying said KEE/PVC roofing patch over said coated area such that that the KEE/PVC roofing patch fully contacts said rubberized tape and covers the said coated area.
A process for reinforcing a seam of a KEE/PVC roofing membrane using a KEE/PVC roofing patch and rubberized tape comprising:
- a) preparing a plasticizer primer comprising a phthalate;
- b) identifying a seam between KEE/PVC roofing membranes;
- c) coating an area around said seam between the KEE/PVC roofing membranes with said plasticized primer;
- d) adhering rubberized tape to said coated area around said seam;
- e) sourcing a KEE/PVC roofing patch large enough to cover said coated area of the KEE/PVC roofing membrane;
- f) coating said KEE/PVC roofing patch with said plasticized primer;
- and
- g) laying said KEE/PVC roofing patch over said coated area such that that the KEE/PVC roofing patch fully contacts said rubberized tape and covers the said coated area.
