Neutral silicone structural adhesive sealant is a kind of high modulus and high elasticity silicone rubber. It with good weather resistance is easy to use and work well in bad weather. Compared with non-structural adhesive, the structural adhesive sealant with high strength can bear high capacity without damaged. And it can form a strong bond with most of materials without primer. So it not only can be used in constructions but also can be used in glass and ceramics industry. Compared with two-component polysulfide sealant, neutral silicone structural adhesive sealant can be used directly without mixing. In addition, our products are non-toxic, non-polluting products. You can use it without any worries.

L-malic acid is an important component of natural fruit juice. Compared with citric acid, it has high acidity (the acidity is 20% stronger than citric acid), but the taste is soft (has a higher buffer index), has a special fragrance, and does not damage the mouth and teeth. It is metabolically beneficial to the absorption of amino acids and does not accumulate fat. It is a new generation of food soursing agents. It is hailed as "the most ideal food soursing agent" by the biological and nutritional circles. Since 2013, it has been replacing citric acid in food for the elderly and children.

L-Cystine powder, CAS No.56-89-3, formed by the oxidation of two cysteine molecules, a non-essential amino acid. It is used as a component for parenteral and enteral nutrition and the main active ingredient for medications used to treat dermatitis. Cystine along with the amino acid methionine are the amino-acids necessary for wound healing and forming of epithelial tissue. Cystine is known to stimulate the hematopoietic system and promote the formation of white and red blood cells.

As an experienced L-Cystine manufacturer and supplier, we has been supplying and exporting L-Cystine for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

Single component polyurethane sealant, as known as a single component, hydrophilic, water activated, hydro active, expandable, gungrade waterstop, is also called single component polyurethane hydrophilic expansion waterproofing sealant. When in contact with water, the sealant expands and produces an expanding pressure. The pressure between the expanded sealant and the surrounding concrete structure prevents water penetration through the joint and provides a durable waterproofing solution.

Advantages
Based on the physical and chemical properties of the polyurethane sealant, it has many advantages. Such as:

Expansion rate. The polyurethane sealant has a strong expansion capacity. It can expand to 220% or 300%, 400%, 500%, even 600% of its own volume.
Strong adhesion. It can used to steel, HDPE, PVC, and other common building materials, and it also effective to damp surfaces.
Good weather resistance. It has low temperature flexibility, and its service life of up to 15 to 20 years.
Environmentally non-toxic. It has good chemical resistance, and it tested can be resistant to hydrochloric acid, salt water, sodium carbonate, potassium hydroxide and other chemicals. In addition, it is safe and non-toxic when in contact with drinking water, belongs to environmentally friendly products.
Ease to use. It can be applied with a standard caulking gun.
Application
Polyurethane sealant is widely used in construction, transportation and other industries. Such as the following usage:

Caulking agent. The polyurethane sealant is used as caulking agent in the construction of subways, tunnels, underground parkings and other projects.
Sealing waterproof. In building construction, it can play a role of sealing waterproof for doors and windows, exterior walls and other parts.
Water stop. It can be used as water stop when punctures are found in plumbing, sewer lines and other utility pipes.

Product feather:
(1)One component, good contact deformation, easy to construct
(2)High strength.
(3)Good compatibility and wide use.
(4)Environmental friendly, pass SGS, ELV standard certification.

Using way
Suitable for bonding and sealing among various materials such as metal, alloy, glass, wood, concrete, marble and ceramics. Can be applied to the construction industry, industry, transportation industry, home appliance industry, furniture industry and other industries. To do some adhesion test before a large number of use. If necessary, do roughening or adding primer before adhesion.

Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method.
