Product Description

POLYSHIELD HT-SLOW-FC™ is a state-of-the-art, high- performance, sprayed, plural-component, pure polyurea elastomer, that is compliant with FDA 21 CFR 175 300 (c)/ (d) high temperature, heat-sterilized, non-acid aqueous food contact. This system is based on amine-terminated polyether resins, amine chain extenders and prepolymers. It provides a flexible, tough, resilient monolithic membrane with water and chemical resistance.

Product Features

  • FDA compliant for incidental and direct food contact.
  • 100% solids. No solvents. No VOCs.
  • Fast-set: Handle in two minutes or less.

Product Colours

POLYSHIELD HT-SLOW-FC™ is available in SPI standard colors (Sand, Medium Grey, and Black). Custom colors are available upon request. It should be noted that POLYSHIELD HT-SLOW-FC™ is an aromatic polyurea; therefore, as with all aromatics, color change and superficial oxidation will occur.

Aliphatic urethane, polyurea, and other suitable aliphatic topcoats can be used where long-term color stability and increased longevity in full sun exposure are of critical importance.
