Instructions for use:

Before mix the A and B part, the user can also change the mixing ratio according to actual needs,(volume ratio between 8:1 ~ 12:1).

In the outdoor temperature environment, don't construct when the substrate surface temperature exceeds 40 °C.

Prior to use adhesive materials compatibility testing to confirm compliance before construction.

Construction materials in contact with the structure of the surface must be clean and dry.

Construction Abstract:

It is not suit to all leaking oil, plasticizer or solvent surface.

Not for frost or wet surface.

Not suitable for long-term immersion or wet places throughout the year.

B component can be react with water vapor in the air, don't exposure in the air for long.

Safety:

It will be cast out of volatile compounds before and during the curing, it will be harmful to health if inhale high concentrations of volatile compounds in long time. Therefore, please pay more attention to maintain good ventilation in the work place.

It is not good to touch the sealant directly for a long time. If it inadvertently enter in the eyes, rinse with plenty of water immediately , if necessary, please ask the doctor for help.

Cured silicone sealant will not release harmful substances, it would not jeopardize the skin too.

If swallow the silicone sealant, please ask the medical treatment immediately .

Keep the children away from it before curing, if swallow, should ask for medical help immediately.

Please put in away from the children.

Q: Preparation of white latex formula and production process: White latex is a water-soluble adhesive, is a vinyl acetate monomer in the initiator under the action of polymerization and made a thermoplastic adhesive. Usually add titanium dioxide (low-grade on the addition of calcium, talc, powder) .After the emulsion polymerization made of milky white thick liquid.

Q: What is meat adhesive?: In simple terms, it is a food additive that binds meat. Used to bind meat or pieces of meat. A lot of beef and mutton manufacturers in the cutting of meat will have a lot of beef and mutton meat or some scrap, with meat adhesive can be the next sub-material into the whole piece of meat and then take the split, Lamb chops or beef slices lamb slices shabu hot pot and so on. Generally the whole piece of sticky meat does not have adhesive traces, and the heating generally does not crack.

Q: Use of sealant: 0 ° C or more, ± 12.5% of the average width of the joint at the time of sealing, 0 ° C or less, the total amount of ± 5% of the average width of the joint

Q: In the conservation company has shares, and later to the toll station, now the toll station withdrawal, you can continue to protect the company to work, what can be based on?: Concrete crack treatment, refers to the scientific approach to the repair of concrete cracks in the technology. Concrete cracks generally have three states: static cracks, active cracks, is developing cracks. The choice of concrete crack treatment methods generally to consider the factors: to determine whether the cracks are active or static; repair the main purpose of what? Is to reduce the excessive leakage, so that the cracks at the complete water; whether the need for reinforcement treatment; crack the main reason is what; cracks in the future changes (value and direction) how. - 13 common methods of concrete crack treatment: 1. resin infusion method; 2. surface sealing method; 3. drilling insert method; 4. flexible sealing method; 5. surface additional reinforcement method; 6. grouting method; . Dry insert method; 8. nail method; 9. polymer immersion method (gravity infiltration and vacuum infiltration); 10. Die surface layer and surface treatment method and so on.

Q: What are the trends in the development of electronic adhesives and sealants?: As the markets of the developed countries are already mature, most companies are moving to developing countries that can provide sustainable market demand in order to avoid threats such as declining sales. According to the new research market report, the Asia-Pacific region's sealant market is expected to reach 8.166 billion pounds by 2017.

Q: Will the kind of adhesive soluble in water (preferably powder), melting temperature of about 800 degrees, was neutral or weak alkaline, thank you!: Alginate is slightly soluble in water and insoluble in most organic solvents. It is dissolved in alkaline solution, so that the solution is viscous. Sodium alginate alginate is hygroscopic and the amount of moisture contained in the equilibrium depends on the relative humidity. The dried sodium alginate is stored fairly stable in a well-sealed container at 25 ° C and below. Sodium alginate solution is stable at pH 5 to 9. The degree of polymerization (DP) and the molecular weight are directly related to the viscosity of the sodium alginate solution, and the decrease in viscosity during storage can be used to estimate the degree of sodium alginate de-polymerization. High degree of polymerization of sodium alginate stability is less than the degree of polymerization of sodium alginate. It is reported that sodium alginate can be catalyzed by proton hydrolysis, which depends on time, pH and temperature. The propylene glycol alginate solution is stable at room temperature at pH 3 to 4; when the pH is less than 2 or greater than 6, the viscosity will decrease even at room temperature. The sodium powder is wet with water and the hydration of the particles makes the surface sticky. The particles are then quickly bonded together to form clumps, and the agglomerates are slowly and completely hydrated and dissolved. Alginate is more difficult to dissolve in water if it contains other compounds that compete with alginate for hydration. Water in the sugar, starch or protein will reduce the rate of sodium alginate hydration, mixing time necessary to extend. A monovalent cation (such as NaCl) also has a similar effect at concentrations above 0.5%. The pH of sodium alginate in 1% distilled water was about 7.2....

Q: OKorder where to sell the United States He can adhesives, sealants? United States Hernon: He was founded in 1978 in New York's Queens. In 1990 the company moved to Sanford, Florida, an area of 25,000 square feet and with the neighboring industries continue to expand the county.

Q: Is there a separate standard for car sealants and adhesives?: Of course there are standards, the vehicle sealant can refer to the Ministry of Transportation industry standards

Q: Polyurethane sealant: Polyurethane sealant is divided into two-component polyurethane sealant and one-component polyurethane sealant two, Hengshui Bazheng Rubber's two-component polyurethane sealant commonly known as A, B material, black and white two-component sealant, it With a seal seal waterproof, adhesive, anti-seepage and other functions. Two-component polyurethane is a polyether, polyisocyanate as the main raw material, then add curing agent, filler and a variety of additives composed of a room temperature reaction curing elastic sealing material.

Q: Is the glass gel an industrial adhesive? And neoprene industrial glue distinction: Glass glue by performance is divided into two kinds: neutral glass glue and acid glass glue. Generally used for home improvement bonding. Home furnishings are generally used in the place of glass glue: wooden line on the back of the mouth, sanitary ware, toilet, bathroom in the make-up mirror, wash basin and wall cracks, etc., these places to use different properties of glass glue. Neutral glass adhesive force is relatively weak, generally used in the back of the bathroom mirror do not need strong adhesion of these places. Neutral glass glue used in home improvement more, mainly because it will not corrode the object, and acidic glass glue is generally used in the wood line on the back of the dumb mouth, strong adhesion.
