2. Good toughness,high strength,fast curing,easy to use.
3. Excellent weatherproofing performance and stability,long life.
4.High modulus after curing,have joint movement capability of 25%.
Main use
1.Assembly and waterproofing&mildew proofing sealingof kitchenware and sanitary ware.
2.Assembly and sealing or window and door glasses.
3.Joint sealing of glass,marble,aluminum plate etc.
Instructions of use
1.Clean and dry the substrate' surface first of all.
2.Cut the nozzle and press glue gun ,balance the glue to the both sides,ensure to full the joint.
Use limitations
RT-678 silicone sealant should not be applied in the following conditions:
a. To all places that bleed oils, plasticizers or solvents, and some uncured or sulfurized rubber.
b. To the unventilated space or the surface which can touch the food or water directly.
c. When the surface's temperature is below 4 °C or above 40 °C
d. To materials contained copper or copper alloy, painted surface, which may cause paint cracking or paint stripping.
e. To the surfaces with lime powder,concrete or sand grain.
f. To structural assembly purpose.
Please read company's technical files before application. Compatibleness test and bonding test must be done for construction materials before application. Our only warranty is the price amount or the product replacement but without any joint and several liability.
Safety
1.It will release volatile compounds before the silicone is cured or during the curing period.It will be harmful to healt if inhale high concentrations of volatile compounds in long time.So ,please pay attention to keep the air fresh on the work place.
2.It is not health if the uncured silicone touch the skin directly for long, if it enter in the eyes, rinse with plenty of water immediately, and then ask the doctor to check if necessary.
3.Cured silicone sealant will not release harmful things, and it would not be harmful to skin.
4.If swallow the silicone ,please ask for medical treatment immediately.
5.Do not let the children to touch the curing silicone, don't put the sealant at children's reach.
Storage period
Keep dry and below 27 °C, storage period is 12 month since the date of production.
