SD838 all-purpose nail-free adhesive
SD838 all-purpose nail-free adhesive is a new type of modified silane sealant with low modulus and high elasticity, which is mainly aimed at solve the problems of joint shrinkage deformation, poor weathering resistance of sealant and poor adhesion between sealant and substrate. The product has excellent mechanical properties, strong resistance to shift, excellent weather resistance, no substrate pollution, non-toxic low VOC, non-corrosive mirror, and have excellent adhesive properties with concrete, stone, ceramics and glass and other substrates and so on.
Multifunctional adhesives can be used for bonding, sealing and repairing cracks.
High-strength bonding force suitable for different substrates: concrete walls, wood panels, ceramic products, metals, stone and so on. It can be used on wet surface.

SD838 universal nail-free glue
SD838MS universal nail-free adhesive is a new type of modified silane sealant with a low modulus and high elasticity single component.
The product has excellent mechanical properties, strong resistance to shift, excellent weather resistance.
No solvent, environmental protection, odorlessness, instant positioning.
Store in a cool and dry place under normal temperature, storage period is 12 months.
The construction surface should be clean and dry. Cover the adjacent surfaces of the glueing with striped rubber paper. Stab aluminum film, cut the tip into 45 degrees, glueing evenly. Use a scraper or latex glove to smooth the glue. Tear off the striped tape before the glue curing. If glue is not used up, natural seal by extruding 1cm rubber wire, and remove the solidified part before next use .
1. Not suitable for: adhesion of smooth surface substrates.
2. Maximum endurance curing time: 24 hours.
3. Construction environment temperature: 5 ℃ ~ 40 ℃.
4. The operating temperature shall not be lower than-20 ℃ or above 65 ℃.
5. Store in a cool and dry place under normal temperature, storage period is 12 months.
