HITAC RA-21S
PATENT PENDING
- Release agent pre-dissolved in recoverable solvent
- Stable solution during transportation, storage, and coating even below freezing temperature
- Prevent clogging the gravure rolls during coating application which decreases production downtime and waste
- Easily integrates into most existing release coater production lines
- Designed to release on most common types of adhesives, such as SIS, SIS/SB, SBR, natural rubber and acrylic based adhesives
- Effective release for most backing materials such as polypropylene, polyethylene, polyester, PVC and paper
- Delivered at 39% Total Solids
HITAC RA-23S
ENHANCED SOLVENT BASED RELASE AGENT
RA-23S is a high total solids solution of a polyurethane release agent in a recoverable solvent. It offers significant improvements over other release agents, such as PVODC.
While most release agent solutions must be maintained above ambient temperatures (~75ºF or 25ºC) by heating to prevent precipitation of the release agent on transfer, storage and coating, RA-23S is stable without heating, even below freezing temperatures, at all concentrations of its solutions. The absence of a heating requirement reduces energy cost, fire hazards, and the possibility of clogging the gravure rolls that could cause inadequate coat weight and thus yielding excessive unwind adhesion and wasted rolls of tape.
