PVC Cut & Curled Jacketing along with PVC Fitting Covers help protect pipe insulation from both UV and the elements.  Proto PVC can be used in both interior and exterior piping applications due to its exceptional outdoor weathering.  PVC is also extremely popular in food/beverage facilities, drug laboratories, and the petrochemical industry.

The main issue with PVC jacketing and fittings is the seams and joints being properly sealed to prevent water.  Proto-One is a specialty adhesive which is designed as an approved closure method in USDA and FDA regulated facilities.

WHAT IS PROTO-ONE Adhesive?

ProtoOne is a multi-purpose, one-part, elastomeric, adhesive sealant formulated from a silane-terminated polymer. This unique elastomeric joint sealant is free from solvents, isocyanates, and other hazardous raw materials. It cures on exposure to atmospheric moisture to form a strong durable bond between two surfaces. Due to its unique properties, it also remains a highly durable flexible seal. It has been formulated to offer outstanding primer-less adhesion to most materials, especially various types of plastics.

FEATURES:

• VOC compliant
• Ease of use, one-part adhesive, no mixing required
• Outstanding bond strength on EXOD 225® CPVC and other difficult specialty materials
• Primer-less adhesion on most damp and non-porous surfaces
• Unaffected by sunlight, rain, snow, ozone, and temperature extremes
• Non-yellowing, non-staining, non-streaking
• Non-corrosive
• Low odor
• Non-flammable
• Free from solvents and osocyanates
• Free-thaw stable
• Can be applied in all weather conditions

INSTALL INSTRUCTIONS:

Step 1 - Cut the tip off of the cartridge, screw on the nozzle, and insert into a professional caulking gun. Be sure to pierce the membrane at the front of the tube before applying pressure.

Step 2 - Apply a 1/8" bead of adhesive for 4" O.D. or less and a 1/4" bead of adhesive for above 4" O.D. along the edge of the product 3/8" from the edge of the overlap. Press evenly on the caulk gun for the length of the part so the adhesive is distributed equally. Allowing the adhesive to seep out slightly from the edge of the overlap is desired and creates a good seal.

Step 3 - Using a clean putty knife, scrape off any excess adhesive along the seam.

Step 4 - Finally, wipe off the area with a clean rag and mineral spirits to finish off the job. Cleanup must be performed before the adhesive has time to set up. If all the contents in the tube are not used, simply allow a small amount of caulk to dry at the tip of the applicator to form a plug and remove when ready to use again.

Due to Proto-One's superior gripping ability, taping is not usually required on pre-curled jacketing, however elbows and other fittings can require taping on some applications. Tooling time allows for about three to five minutes before Proto-One starts to form a skin and set in, however factors including ambient temperature and humidity can affect this. Additionally, a water misting spray should be used on the caulk bead to accelerate the activation time when applying ProtoOne in low humidity and dry climate environments.

Proto Corporation recommends a minimum of twenty-four hours before removing any tape so the adhesive has time set up and create a seal. Proto-One cures approximately 50% within 24 hours and approximately 90% within 48 hours. Optimum strength is achieved in seven days.
