Product Description

1. One-component ; neutral curing; High adhesion; high-strength ;
2. Excellent adhesive sealing and extensibility with mostly building material
3. The product generate hardy heat-resistant non-corrosive elastomer after solidification;  It lasts long time because it's excellent capacity of weatherproof, anti- oxidation, resistance to ultraviolet radiation and resistance to high and low temperature changes.

Main application
1, Aluminum plate; Aluminous model board; stone material(marble,granite);Adhesive seal between aluminum alloy
2,Glass, ceramic tile, brick and concrete etc;
3,all kinds of coating material;  oil tight wood.

1,Can not be used for surface will exudes plastic plasticizer or solvent which will cause property damage
2,Not recommended for fully sealed space will not completely cured by leaking water vapor
3,Temperature below 4 degrees or higher than 10 degrees is not suitable for construction

1.   Volatile compounds will be released when the products are not completely cured. It's harmful for long-time-breathing volatile compounds that being sure there is adequate ventilation
2.   Don't let not cured adhesive contact with eyes and skin for long time. If it happens, washing them with clean water immediately or find a doctor if it is necessary.
