LUCKY-SILICONE LC 798
WACKER® LC 798 is a one-part, neutral alkoxy silicone sealant with outstanding adhesion to most building substrates. It has excellent weather resistance and durability, and especially shows excellent adhesion to plastic materials such as polycarbonate, PMMA, and ABS.
WACKER® LC 798 cures at room temperature in the presence of atmospheric moisture to give a
permanent flexible silicone rubber.
- Excellent weather resistance
- Excellent durability
- Good elasticity
- Good adhesion
- Non-corrosive to metals
- Suitable for plastic
- Polycarbonate, PMMA and ABS Joint sealing.
- Preparation - The substrate areas that will be in contact with the sealant must be clean. For application.
- Masking - To avoid contamination and damage attach a masking tape on the side of work area.
- Primer - Non-pored substance needs primer treatment at first.
- Sealing & Tooling - Fully fill in cross point or side edge point of the joint without empty space without bubbles.
- Curing - Protect from dust and pollutant to have qualified surface and avoid being damaged on the surface of sealant while curing
- WACKER® LC 798 is certified and classified KS F 4910 F-25LM / HB(TVOC) certificate.
- WACKER® LC 798 exhibits excellent primeless adhesion to most non-porous siliceous material, e.g., glass, tiles, ceramics, concrete. enamel, glazed tiles, and clinker Users must carry out their own tests due to the great variety of substances. The adhesion can be improved in many cases by pretreatment of the substrates with a primer. If adhesion difficulties areas, please contact our technical service.
Restrictions on use
- It is the user's responsibility to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coating materials (paints, varnishes, and glazes) or organic plasticizer containing rubbers (EPDM, butyl and neoprene) can lead to discoloration or other impairments like loss of adhesion of the sealant. Materials in direct contact with the applied sealant like cleaning agents and materials in indirect contact like gaseous emissions can damage the sealant in its function or change its appearance. Because of the multitude of these materials. Wacker cannot make a general statement to the compatibility of materials with the sealant. In case of doubt the user shall conduct appropriate preliminary tests.
- WACKER® LC 798 must not be used for insulating glass applications.
- WACKER® LC 798 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.
- WACKER® LC 798 may be discolored in contact with some WACKER® LC 1100, e.g. EPDM, APTK and neoprene.
- WACKER® LC 798 should not be used for sealing of aquaria.
- WACKER® LC 798 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.
- WACKER® LC 798 is not recommended for structural glazing bonding.
- WACKER® LC 798 should not be used in contact with metals such as lead, copper, brass, or zinc due to corrosion.
- WACKER® LC 798 is not recommended for sealing of aquaria or for longer-term use under water.
- WACKER® LC 798 is not suitable for food grade applications where the joints are likely to come in contact with food.
- WACKER® LC 798 is not suitable for use as a mirror adhesive.
- The time until complete curing may be extended at lower temperature, lower humidity, increasing film thickness or by low volume of air exchange.
The use of tooling agents should be avoided if possible. Otherwise, water or a diluted solution of a little neutral soap or alcohol in water should be sparingly applied.
