ULTRA BOND-HT-FC™ is a high tensile, high elongation, high build, fast set, elastomer, that is compliant with FDA 21 CFR 175 300 (c)(d) high temperature heat-sterilize, non-acid aqueous food contact, specifically formulated to provide a tenacious bond to certain thermo- set plastic surfaces. Unlike most spray applied Polyureas ULTRA BOND-HT-FC™ has the unique advantage of adhering to many polymeric substrates, both new and aged, typically without the use of primers or extensive surface preparation.
In house testing has shown excellent adhesion to certain clean, dry surfaces including:
- Primers Past the Recoat Window
- Latex Rubber
- Crumb Rubber Surfaces
- Firestone SBS Roofing Membrane
- SBR Rubber
- Aged Polyureas
- Automotive Finishes
- Sarnafil Vinyl Roofing Membrane
- Line-X Bed liner
NOTE! Polymer formulations vary. It is recommended that adhesion tests be performed before commencing any project using ULTRA BOND-HT-FC™. For adhesion verification SPI encourages you to submit your (substrate) sample to SPI to be sprayed and tested.
*It is recommended that oxidized surfaces be power washed with 2500 – 3500 psi water pressure to achieve maximum adhesion of ULTRA BOND-HT-FC™. If there is a possibility of surface contamination, scrub with a solution of 1⁄4 tsp Dawn detergent plus 1 tbsp of Vinegar, per 1 gallon of warm water, followed by a thorough water rinse.
SPI Prep Wipe™ applied prior to application of ULTRA BOND-HT- FC™ generally increases adhesion to certain finishes.
- Coating over organic primers that are past their recoat window. These include SPI POLYPRIME-100™ and EP- 100™
- Repair of Polyurea liners
- For texturing aged Polyurea
- Top coat compatible existing membrane liners
- Recoat urethane liners
- Recoat over other polymer based substrates used for
- flooring, wall covering, and infrastructure protection
ULTRA BOND-HT-FC™ is available in several standard colors (Sand, Medium Gray and Black). Custom colors will be quoted upon request.
It should be noted that ULTRA BOND-HT-FC™ is an aromatic Polyurea; therefore, as with all aromatics, color change and superficial oxidation will occur.
Aliphatic urethane, polyurea, and other suitable topcoats can be used where long-term color stability and increased longevity in full sun exposure are of critical importance.
