Acticide Lv 508 New

ACTICIDE LV 508 (marketed by THOR) is an aqueous-based fungicide primarily composed of sodium pyrithione (NaPT), with a typical active ingredient concentration of approximately 40%. It is engineered for the preservation of industrial products in their "wet state," specifically targeting fungal and yeast growth. Key Specifications & Applications Active Composition: Aqueous-based sodium pyrithione.

The Role and Impact of ACTICIDE® LV 508 in Industrial Preservation Introduction acticide lv 508 new

Compatibility: Designed for "formaldehyde-free" and sensitive aqueous systems. ACTICIDE LV 508 (marketed by THOR ) is

Incompatible With:

• Strong reducing agents (e.g., sodium sulfite, sodium metabisulfite) – will neutralize the isothiazolinones.
• High pH (>9.5) – prolonged exposure leads to ring-opening of the isothiazolone ring, causing loss of activity.
• Amines at >1% – certain primary amines can react with Bronopol, reducing efficacy.
• Elevated temperatures (>80°C) – add only after the batch has cooled below 60°C.

Specific Benefits of the "New" Variant:

• Improved Compatibility: Reduced interaction with thickeners (e.g., HASE and HEUR) that previously caused gelation.
• Lower Use Rate: Typically effective at 0.05%–0.15% (w/w) vs. 0.15%–0.3% for older biocides.
• Green Chemistry Compliance: Meets EU Ecolabel, Blue Angel, and Nordic Swan criteria for preservatives in paints.

Compatibility: It is designed to be used in conjunction with other preservatives for a broader spectrum of antimicrobial activity. Strong reducing agents (e
