Q1: What types of formulations is MERGAL K14 typically used in?
A: MERGAL K14 is primarily formulated into water-based industrial coatings, adhesives, construction chemicals, and aqueous polymer dispersions where long-term protection against bacteria, yeasts, and fungi is required.
Q2: How does MERGAL K14 differ from other isothiazolinone-based biocides?
A: MERGAL K14 is a stabilized blend of active isothiazolinones designed for enhanced stability in alkaline and high-solids systems, offering broader pH compatibility and reduced volatility compared to some conventional isothiazolinone solutions.
Q3: Is MERGAL K14 suitable for use in products intended for indoor applications?
A: Yes — when used at recommended dosage levels, MERGAL K14 supports low-VOC and low-odor formulations commonly specified for interior paints, wall coatings, and sealants, subject to compliance with applicable regional safety and emissions guidelines.
Q4: What is the typical dosage range for effective microbial control?
A: Dosage depends on formulation requirements, but MERGAL K14 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight of the final product — with optimal performance determined through challenge testing under representative conditions.
