| Patch Rubber Company
offers the option of either Heat Cure or Dual Cure bonding gum as well as Uncured repair
units so you can select a repair unit that fits your needs. All Heat Cure and Dual
Cure repair units are cured at the factory under ideal pressure and temperature conditions
assuring correct positioning of the ply package, rubber coverings, and gum strips.
No matter which type you choose, our tire repair units are designed to be user-friendly in
less than ideal conditions. |

Uncured Repair Units 
Uncured Repair Units must be applied with heat and pressure. They
will not chemically cure. These repair units provide maximum adhesion and
maximum flexibility during installation. |
| |
Maximum Adhesion
When cured by heat and pressure, these repair units provide the maximum adhesion
available. Additional floater gum insures a proper bond even with slight
imperfections at the buff. |
| |
Maximum
Flexibility
Because of the
uncured condition, the repair units are more flexible to make installation for the
repairman easier. |
| |
Cement Application Procedures
Apply uncured repair units with Black Brush Type Cement in curing systems that can
vulcanize an uncured tire repair unit (section mold - Autoclave with temperatures 260°F
and higher). |
| |
Dual Cure Repair Units
Dual Cure Repair Units chemically
vulcanize at room temperature or when heat and pressure are applied. Dual Cure
Repair Units provide many benefits to the tire repairman: |
| |
User
Friendly
Our soft, high tack gum is
less prone to problems associated with moisture, handling, and cement drying time,
allowing easy application. |
| |
Superior Green Tack
Soft and tacky Dual Cure Base Gum "locks" the repair unit in place until
a full cure has occurred. |
| |
Optimal Adhesion
Dual Cure Bonding Gum has over twice the adhesive strength of chemical cure repair
units. |
| |
Flexibility In Use
Depending on your need, Dual Cure Repair Units will fully cure during the
retreading process, in a section mold, or with the heat and pressure created by a tire in
service. |
| |
Cement Application Procedures
Apply Dual Cure Repair Units with Fast-Dry Self-Vulcanizing
Cement. |
| |
Heat Cure Repair Units
Heat Cure Repair Units must be
applied with direct heat and pressure. They will not chemically cure.
Heat Cure Repair Units provide many benefits to the tire repairman:
|
| |
Maximum Adhesion
When cured by heat and pressure, these repair units provide superior adhesion over
chemically cured patches, and equivalent adhesion to uncured (green or raw) patches. |
| |
A Permanent Repair
During the curing process, the layer of Bonding Gum flows into imperfections in
buffed surfaces acting as a "safety factor" for less-than-perfect application
procedures. Because of increased adhesion to the tire casting, fewer units need to
be removed prior to subsequent retreading cycles. |
| |
Improved Appearance
The heat cure repair units are cured at the factory which provides an improved
appearance over uncured repairs. Repair Units feather into the tire innerliner,
giving the repair an almost unnoticeable appearance. |
| |
Cement Application Procedures
Apply Heat Cure Repair Units with Black Brush Type Cement in curing systems which
typically can vulcanize a totally uncured tire repair unit. (Section Mold-Autoclave:
Curing temperatures 260° F and higher.) Apply with Fast-Dry Cement in curing
systems which provide marginal heat conditions. (Repairing while retreading in molds
and chambers.) Chamber curing at 210° F may not provide sufficient temperature for
proper vulcanization unless standard curing time is increased. |
