Anti mold silicone sealant is the core sealing material for damp scenes in kitchens and bathrooms. The core is 0-level anti mold, neutral curing, and long-lasting waterproofing. Below, we will explain the core parameters, types, selection, construction, and brand from all dimensions.
1、 Core definition and key indicators
Anti mold silicone sealant is a single component, moisture cured elastic sealant that contains anti mold agents such as silver ions and isothiazolinone to inhibit the growth of mold/bacteria.
Mold proof grade (GB/T 1741-2007):
Level 0: The highest standard, with no obvious mold under a 50x magnifying glass (a must-have for kitchens and bathrooms)
Level 1: A small amount of mold can be seen under the magnifying glass
≥ Level 2: Not recommended for use in kitchens and bathrooms
Curing type (must see):
Neutral alcohol/ketoxime type: non corrosive, low odor, suitable for metal/glass/tile/marble (preferred for home decoration)
Acidity: It has a vinegar like taste and can corrode metals and coated glass. It is only used for ordinary glass
Core performance:
Temperature resistance: -50 ℃~150 ℃, maintaining elasticity
Elongation rate: ≥ 400%, suitable for thermal expansion and contraction
Environmental protection: Formaldehyde/benzene not detected, preferred with French A+and German GEV EC1 PLUS certification
2、 Mainstream types and applicable scenarios
- Neutral alcohol type anti mold adhesive (preferred for home decoration)
Representatives: Wacker DA, Sika 193, Baiyun SS608
Features: 0-level anti mold, odorless, non corrosive, fully certified for environmental protection
Applicable: shower room, bathtub, basin, toilet, kitchen countertop, sink, hospital/clean room - Neutral ketoxime type anti mold adhesive
Representatives: Dow Corning 791, Silicon Treasure 998
Features: Good mold resistance, fast curing, high cost-effectiveness
Applicable: Kitchen and bathroom ordinary seals, doors and windows, balconies - Acidic anti mold adhesive (use less)
Features: Strong adhesion, low price, but with sour taste and corrosive metal
Applicable: Only for ordinary glass sealing, strictly prohibited for use with metal/coating/marble
3、 Key points for purchasing (avoiding pitfalls list)
Check the anti mold level: Kitchen and bathroom must choose level 0, reject the vague promotion of “long-lasting anti mold”
Check the curing type: Choose alcohol type/ketoxime type for home decoration, avoid acidity
Environmental certification: Priority given to French A+, German GEV EC1 PLUS, SGS
Look at brand and packaging: Legitimate brands have clear models, implementation standards, and production dates; Reject the Three Nos
Color: Commonly used porcelain white/transparent in kitchens and bathrooms, matching with tiles/countertops
4、 Standard construction process (determining lifespan)
Base treatment: clean and dry, free of oil stains/dust/old glue, and polished if necessary
Apply masking paper: Apply masking paper to the edges to ensure a straight adhesive seam
Glue application: Cut the glue nozzle at a 45 ° angle, squeeze it out at a constant speed, and make it full without any gaps
Scrape flat: Use a scraper/finger dipped in water to scrape flat, immediately tear off the decorative paper
Curing and maintenance:
Surface drying: about 30 minutes
Initial curing: 24 hours (do not touch water)
Fully cured: 7 days (reaching maximum strength and anti mold effect)
5、 High reputation brands and models (recommended in 2026)
International high-end (level 0+environmentally friendly top configuration)
Wacker DA: Alcohol type, Grade 0 anti mold, French A+, German EC1 PLUS, kitchen and bathroom top configuration
Sika 193: Alcohol based clean taste, grade 0, non corrosive, suitable for hospitals/food workshops
DOWSIL 791: Ketoxime type, Grade 0, strong weather resistance, universal for engineering and home decoration
Domestic high-quality (high cost-effectiveness)
Baiyun SS608: neutral, grade 0 anti mold, excellent weather resistance, industry leader
GUIBAO 998: Neutral, long-lasting anti mold, good waterproof, popular for home decoration
Saint Gobain CE811: medium low modulus, grade 0, temperature resistance -40 ℃~150 ℃
Sanhe EC556: Grade 0 anti mold, neutral, affordable, suitable for rental housing/simple decoration
6、 Common problems and pitfalls to avoid
❌ Misconception 1: Using ordinary glass glue instead of anti mold glue → Black and moldy will occur within 3-6 months
❌ Misconception 2: Acidic glue used for metal/marble → corrosion, discoloration, and peeling
❌ Misconception 3: Immediately wet after gluing → Poor curing, ineffective mold prevention
✅ Correct: The kitchen and bathroom must use grade 0 neutral anti mold glue, and avoid water within 7 days after construction
