In the world of industrial microbiology, the battle against microbial contamination is unending. For formulators in paints, polymers, adhesives, and detergents, finding a preservative that balances efficacy, safety, and regulatory compliance is a constant challenge. Enter Acticide LV 508 New—a revolutionary, low-VOC (Volatile Organic Compound) biocide designed to redefine wet-state preservation.
This article provides a deep dive into the chemistry, application, benefits, and safety profile of Acticide LV 508 New, explaining why it is rapidly becoming the gold standard for manufacturers worldwide.
Problem: A midsize paint producer experienced recurrent in-can spoilage (gas formation, pH drop from 8.5 to 6.0) within 4 weeks of storage, despite using 0.15% of a standard OIT/MIT blend. Solution: Switched to Acticide LV 508 New at 0.20%. Result: After 6 months of accelerated aging (50°C storage), no microbial growth was detected. The preserved paint passed the 28-day challenge test against Pseudomonas aeruginosa, Staphylococcus aureus, and Aspergillus niger. acticide lv 508 new
Compatible with most raw materials except:
Note: Always conduct a jar test for compatibility with your specific resin system. In the world of industrial microbiology, the battle
The required dosage depends heavily on the susceptibility of your specific formulation to microbial attack.
Effective use of Acticide LV 508 New requires correct dosing and incorporation. Below are general recommendations, though specific optimization should be done via challenge testing (e.g., ASTM E640, EPA MB-27-02). Note: Always conduct a jar test for compatibility
| Application | Recommended Dosage (wt%) | Temperature Range | Incorporation Notes | |-------------|--------------------------|-------------------|----------------------| | Paints & coatings | 0.10% – 0.25% | 5 – 60°C | Add during the let-down stage after pH adjustment | | Adhesives | 0.15% – 0.30% | 10 – 50°C | Add under low shear mixing | | Metalworking fluids | 0.20% – 0.40% (concentrate) | Ambient | Add to concentrate; for sump dosing, use 0.10% every 7 days | | Mineral slurries | 0.05% – 0.15% | 5 – 40°C | Add prior to storage tank filling | | Cleaning products | 0.10% – 0.20% | Ambient | Add as final ingredient; avoid high pH shock (>9.5) |
Critical Process Note: Always add Acticide LV 508 New to the water phase before adding thickeners or rheology modifiers. This ensures uniform distribution. Do not add directly to empty vessels—dilute first with a small amount of water to prevent localized over-concentration.
A: 12 months from date of manufacture when stored in original sealed container at 5–40°C. Avoid freezing.
Acticide LV 508 is typically an in-can preservative used to prevent microbial growth in liquid products.
