Features:
CC4890W for the one-component construction adhesive caulking off oxime silicone adhesive sealant, with the adhesive in addition to the general advantages of silicone rubber, offers the following key features:
1, the adhesive is a self-leveling type, the flow of good, able to automatically flow into the joints, and fill the gap without trimming;
2, neutral curing system for concrete, stone and other substrates free from corrosion, and has good adhesion;
3, the product construction is convenient, good weather, aging performance.
Second, the typical use:
Mainly used for tunnels, bridges, roads, airport runways, squares and other sealing joints and cracks of concrete repair.
Third, the use of technology:
1 Clean the surface: the clean surface and internal cracks, and in addition to dirt and oil and so on.
2, glue: The glue has been pushed to clean up in the slot, let the natural flow levels.
3, curing: in the air let it cure. Curing process is a cure from the surface to the internal process within 24 hours (at room temperature and 55% relative humidity) glue will solidify the depth of 2 ~ 4mm, if the position sizing deep, especially in the air is not easy to come into contact with the site, full cure time will be extended, if lower temperatures, curing time will be extended, 6mm thick sealant is fully cured to be more than 7 days time

VI Notes:
■ according to requirements once the best run out. Operation is complete, unused plastic should be covered immediately tighten the cap or lid, sealed. Again, if the seal has a little crust, can be removed without affecting normal use.
■ uncured rubber, such as accidentally invade the mouth, eyes, immediately wash with water and medical treatment.
Seven, storage and transportation:
1, the product should be below 35 ℃ in a cool dry environment storage, the following storage at 25 ℃ for 1 year.
2, these products are non-dangerous goods, according to the general chemicals. Leakage during transport careful!
3, more than the product shelf life should confirm whether the abnormality before use.
