Biocides are pesticide-class -- wear PPE and consult SDS. At compliant dosage, cured film is safe. Export requires attention to local regulations.

7. How to choose the right fungicide?

Consider 4 factors: 1. Protection stage (in-can/dry-film); 2. Coating system (emulsion/pH/PVC); 3. Target market regulations; 4. Compatibility testing (small batch, 50degree*72h).

AI-Powered supplier vetting

SummaryQingdao New Sanda Industry Co., Ltd. is identified as both a trading company and manufacturer/factory in China, focused on chemicals and construction-related products. The supplier reports ISO-series management certifications, two production lines, 21–30 quality-control staff, and peak- and off-peak order fulfillment within 15 working days. Its stated capabilities include R&D, customized formulations, formulation optimization, application testing, troubleshooting, multilingual documentation, and after-sales support. The supplier reports extensive export coverage and began exporting in 2015, but the available trade evidence shows only one recorded transaction and one associated buyer. Financial credibility cannot be assessed because financial data is excluded from evaluation.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its stated business focuses on chemical products and industrial additives, including Titanium Dioxide, HPMC, VAE, HEC, CMC, and related materials.

CertificationsThe supplier lists ISO 9000, ISO 14001, ISO 9001, ISO 14000, and ISO 20000 certifications. These stated certifications provide explicit evidence of certified management-system coverage, although the slices do not provide certificate numbers, validity dates, or scope details.

After-Sales capabilityThe supplier states that it provides after-sales service, multilingual documentation, formulation optimization, application testing, and troubleshooting. These are explicit service offerings supporting customers after product delivery.

R&D capabilityThe supplier describes a dedicated R&D team, technical innovation, market-responsive product development, and feedback integration from global partners. It also reports total R&D engineer experience of 11–20 years, supporting an established innovation function.

Production capacityThe supplier presents itself as a chemical manufacturer and reports two production lines, 21–30 quality-control staff, and fulfillment within 15 working days in both peak and off-peak periods. Its product portfolio and end-to-end commercial supply description support production capability, although total output details are not evaluated here.

Customization capabilityThe supplier explicitly offers customized formulations for specific application challenges and provides formulation optimization, application testing, and troubleshooting. Its process includes sample testing through full-scale commercial supply, indicating support for tailored industrial additive solutions.

Product Q&A

Q:1. Why do water-based coatings get moldy?

Water-based coatings contain nutrients (water, cellulose, emulsions). Under 25-35degree and high humidity, mold and bacteria multiply, causing odors, spots, and spoilage.

Q:2. In-can preservative vs. dry-film fungicide --what's the difference?

In-can preservative prevents spoilage during storage (odor, deterioration). Dry-film fungicide prevents mold and algae on the paint film. They serve different stages and cannot substitute each other.

Q:3. What is the recommended dosage?

In-can preservative: 0.05%-0.25%. Dry-film fungicide: 0.25%-2.0%. Increase in hot/humid conditions. Final dosage verified by testing.

Q:4. Common chemical types?

Isothiazolinones (MIT/CMIT/BIT/OIT/DCOIT), pyrithiones (ZPT), benzimidazoles (Carbendazim/BCM), carbamates (IPBC). Isothiazolinones are most widely used.

Q:5. Why mold still grows even with fungicide?

Possible reasons: 1. High film porosity absorbs moisture; 2. In-can only, no dry-film fungicide; 3. Poor application conditions; 4. Incompatibility/degradation.
