8921(HT-921) high performance polyurethane sealant is one component, high thixotropic, flow resistance, low odor polyurethane adhesion. Low viscosity, good thixotropy, facilitating manual operating. After cured, the sealant is elastomer, bearing good properties, such as cold and hot resistance, stress changes resistance. Can be painted, non-corrosive, not flowing working facade and top. It is widely used for various base materials.

Sealings and low bonding strength for passenger car air conditioner, weld, luggage, ships, locomotives, construction, coating industry.

?        310ml/cartridge, 9 months

?        600ml/sausage, 6 months

?        Surface preparation: Clean all dirty, dust, loose particles by steel brush and clean all oily things with cleaning agent. All former adhesive must be cleaned out by scraping, paring, friction, jet of strong air or suitable ways. Make sure the surface be clean, free of dust and grease

?        Cured: The environment temperature and humidity will have great effect on the tack free time and curing of polyurethane. Low temperature causes slow curing; high humidity causes too fast tack free time. The best operating environment conditions as follows: the temperature 20 ~ 30 ℃, humidity 50 ~ 70% RH; please careful construction, if over this range. In the process of sealing and curing, avoid contacting with hydroxyl, amino and other chemical thins which will impact the curing of polyurethane.

?        Not contact sealant with food or cosmetics;

?        Not contact skin for long time about uncured sealant;

?        Rinse eyes with large quantities of water and seek medical check if sealant drops into eyes;

?        Not put sealant out of children

Reliance will sample all related material and do testing to decide best adhesive type and best performance to preventing any potential problems. Please ask for Reliance's technician fro specifics.
