Environmentally friendly polyurethane sealant 
 DM-600 (gray) 
 Advantage 
 (1) reaction of the two-component room temperature curing, does not contain tar pitch, does not contain solvents, toxic pollution. 
 Good elasticity and strong bonding, elongation, and resistance to deformation. 
 Plane dedicated (L) / facade-specific type (N type). 
 Recommended for 
 A concrete construction of the settlement joint, expansion joints, construction joints, split seam sealed waterproof. 
 Airport runway, high-grade highways, bridges and other engineering caulking to seal waterproof. 
 3. Potable water pool, swimming pool and out of the nozzle waterproof seal. 
 Building roof, wall panels, floor, balcony, door frames seam sealed waterproof. 
 Paste all kinds of insulation board, decorative plates, polymer waterproofing membrane and so on.

 Use 
 (1) construction joints need to clean up; 
 Such as the seams deep and width than the first filling foam strips, and then caulking; 
 Sealant preparation: before use group B Stir well, then press the A (main agent) / B (curing agent) = 1/2.5 4 (mass ratio) ratio will be mixed using an electric mixer, stir uniform; 
 (4) preparation of a good sealant pouring or embedded artificial poured required the construction of cracks, such as seam deep separable embedded. 
 After caulking should be checked in time finishing, caulking uniform and dense, smooth surface; 
 Dosage Calculation: 1.3 * Length (m) width (m) * height (m) (t) 
 Packing: iron drum packing group A 15kg / barrel, Group B were 37.5 kg / barrel.
