Application Guidance

Propylene Glycol 60% Inhibited is a glycol-based heat-transfer and freeze-protection fluid. Concentration sets the freeze and burst protection; the inhibitor package sets how long the system stays protected from corrosion.

Closed-loop heat transfer and process cooling
Data-centre and chilled-water freeze protection
HVAC hydronic loops and glycol makeup
Freeze and burst protection for idle or seasonal systems

必要な凍結・破裂防止性能に対して濃度を確認し、使用温度におけるエラストマーおよび金属材料との適合性を確認してください。食品または飲料水への偶発的な接触が起こり得る用途には、USPグレードまたは食品グレードのプロピレングリコールのみが適しています。インヒビター入りグレードは密閉系の熱媒体用途専用です。

Storage & Handling

Recommended Storage: 酸化剤から離れた冷暗所に密閉して保管すること。規定の凍結温度以下での凍結を防ぐこと。ステンレス鋼、炭素鋼、ポリエチレン又はポリプロピレン製の容器。Adjudicated
Handling Precautions: 耐薬品性手袋および飛沫防護ゴーグルを着用してください。高温の表面や高温のプロセス機器との接触を避けてください。インヒビターは使用中に消耗します。やみくもに補充せず、監視してください。Class-level guidance — not product-specific; the SDS controls.
Incompatibilities: 強酸化剤、強酸、強塩基。Adjudicated
Shelf Life: Consult Technical Services for product-specific shelf life

For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
