Bathroom and Kitchen Silicone Sealant is a first-grade anti-fungal neutral silicone sealant specially formulated for use in hot, humid conditions such as bathrooms and kitchens. Cures to form a flexible, waterproof seal, and contains fungicides for use in sanitary applications where protection against mould, mildew, and fungus is required.
YS 388 has been specifically formulated for use in electrical/electronic production and assembly because it:
- has good dielectric properties
- has high surface resistivity
- resists electrical tracking
- repels water to protect electrical properties
YS 388 electronic grade silicone is a neutral-cure silicone that emits no objectionable odors during cure and is ideally suited for use in confined areas. However, adequate ventilation should be provided when YS 388 is used in large-scale production.
YS 388 is a 100% silicone and has excellent resistance to:
- ozone
- UV
- airborne chemicals
- temperature changes from -57 C to +204°C (-70°F to +400°F)
TYPICAL USES
YS 388 electronic grade silicone is an excellent sealant/adhesive for many electrical and electronic applications where corrosion to metals, particularly copper, brass, silver, etc., is a problem. Such applications include:
- lead-wire entries
- conduit terminal boxes
- component mounting
- electrical connections
- conduit ends
- splices
- cover plates
- coaxial cable connectors
- printed circuit boards
- conductor entry holes
SURFACE PREPARATION
All surfaces should be clean and dry. It is recommended that bonding surfaces be solvent wiped with oil-free solvents, such as xylol, toluol naphtha or non-flammable chlorinated solvents. Do not wipe with oil-based solvents such as Varsol. Allow surface to dry thoroughly before applying sealant.
DIRECTIONS
YS 388 electronic grade silicone is ready to use and requires no mixing or additives. The cure mechanism begins as soon as the sealant comes in contact with the air. At conditions of 25 C (77° F) and 50% relative humidity, the sealant will skin in 15 minutes and fully cure within 48 hours (1/8 bead).
Higher humidity accelerates cure. Tooling should be done before skinning takes place.
In applications where partial total confinement of sealant is prevalent, the time required for proper cure is lengthened by the degree of confinement.
PRIMING
Priming of YS 388 electronic grade silicone is normally not required for application to most substrates.
Unprimed adhesion can be readily tested by applying a small trial bead and allowing 7 days for maximum adhesion to occur.
If primer is required, contact YS for technical assistance.
COLORS
YS 388 is available in clear and white. Special colors are available upon request. Call for price and availability.

Cartridge package: 280ml, 300ml /pc , 24 pcs/ carton.
Sausage package: 590ml, 600ml/pc , 20 pcs /carton.
12 months stored in cool(below 27°C), dry, and ventilated places.
Notes:
Avoid long-term contact with skin.
Avoid contact with food, medicine or cosmetics, etc.
Place carefully and ensure that the children keep away from the sealant.
In case of contacting with eyes, wash with plenty of water immediately.
Method of application:
1. Surfaces, where silicon shall be applied, must be cleaned, dried and free of grease.
2. Inject the sealant by a hand-operated or pneumatic caulking gun and fill the sealant in the joints. For better appearance, cover outside of the joint areas with masking tapes before application. Remove the masking tapes immediately after finishing.
