SANDAO polymer adhesive has been tested by the third-party testing organization in terms of mechanical testing, product qualification, material characterization, and microbiological evaluation. In some cases, it can achieve flame retardant, weathering, and thermal conductivity properties2.
Drinking pure water treated by this product facilitates the balance of aqueous electrolytes inside the body, speeds up the metabolism, and excludes the harmful substances. It does not cause any corrosion to the material3.
The product is environmentally friendly. It contains only little toxins that would be harmful and it is profitable for recycling. It is resistant to high temperature and low-temperature alternation4.
It has a unique ability to direct specific light to a specific location. It can focus on a precise area because this product uses its energy much more effectively to deliver the light exactly. The product has good aging resistance
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.
