Silicone Fungicide | Silicone Biocide Anti-Mildew Additive for Silicone Rubber, RTV Sealant & LSR
Meta Description:
Our silicone fungicide and silicone biocide is an antifungal additive for silicone rubber. Good compatibility with platinum cure silicone, RTV silicone sealant and LSR liquid silicone rubber. Low dosage, non-blooming mould inhibitor for silicone compound. Free sample available.
Our silicone fungicide, also known as silicone biocide, is a professional anti-mildew additive for silicone rubber. It suits RTV sealant, LSR liquid silicone rubber and platinum cure silicone, providing built-in long-term mould inhibition with no yellowing and non-blooming properties.
Pain Points:
Many silicone finished products suffer from mildew growth in humid environments. Black mould spots, strange odour and surface discoloration easily appear on silicone sealants, kitchen silicone parts and bathroom silicone accessories.
- Standard silicone raw materials have no antifungal property. Finished goods fail anti-mildew tests and get rejected by buyers.
- Common antifungal additives are incompatible with platinum cure silicone, slowing down curing, hurting transparency and mechanical properties.
- Poor heat-stable biocides break down during vulcanization, lose antifungal effect or cause obvious yellowing.
- Narrow antifungal spectrum cannot inhibit multiple mould strains for kitchen & bathroom end applications.
- Poor dispersion leads to uneven mould resistance, unstable quality in mass production.
Our Solution:
Our silicone fungicide biocide is an internal additive designed specially for silicone systems. It is mixed into silicone compound before vulcanization to achieve permanent built-in anti-mildew performance instead of surface coating.
- Excellent compatibility with RTV silicone, LSR liquid silicone rubber and platinum cured silicone. It will not affect curing speed, transparency, tensile strength or elongation of silicone.
- Broad antifungal spectrum, effectively inhibits Aspergillus niger, Penicillium, Candida and other common moulds.
- Good thermal stability, keeps active under silicone vulcanization temperature, no decomposition and no yellowing.
- Easy to disperse evenly inside silicone matrix, stable anti-mildew performance for whole batches.
- Low addition dosage, high efficiency, simple operation for continuous factory production.
- Silver ion grade optional for customers who need combined antibacterial and antifungal functions.
