1, product description

PVB adhesive strength modifier is a kind of oligomer with many functional groups, has good compatibility with PVB, PVB groups by physical entanglement and chemical grafting, thereby improving the water resistance of PVB, bonding The strength, especially in low temperature environment, the bonding strength greatly improved, in which the bonding strength is particularly significant.

PVB bond strength modifier and PVB have good compatibility, does not affect the optical properties of PVB (transmittance, haze), does not affect the PVB processability, aging resistance and physical properties, and added additives (Plasticizers, antioxidants, UV absorbers, etc.) does not react.

2, product characteristics

① improve the bonding strength of PVB film and glass significantly

② improve the bonding strength of PVB film and glass at low temperature

③ improve the anti-aging properties of PVB film

④ improve the lasting adhesion of PVB film and glass

⑤ and PVB additives do not react

⑥ no volatile, odorless, non-toxic

3, typical physical properties

Appearance colorless and transparent solution

Multifunctional oligomers

Density 1.02

Solubility soluble in water. Slightly soluble in most alcohols, esters and other solvents

4, application

In PVB film production process, the use of resin or corner back to raw materials for the processing of the formula, the bonding strength is a very important control index, when the resin or corner back to the bond strength decreased, often need to add help Agent to stabilize or increase the adhesion of PVB.

Japan Okada Chemical PVB bond strength improver with its excellent properties, get Japan Sekisui, Christie Europe and other PVB manufacturing company's identity, so far in use.

Compared with the currently available adhesion promoters such as silanes and citric acid on the market, Japan Okada Chemical Co., Ltd.'s PVB bond strength can increase the binding force moderately and efficiently and maintain the adhesion between PVB and glass , Especially at low temperatures.

Applications:

This product is suitable for PVB resin, scrap, frit and any other formula

When the PVB products percussion value of about 7, add 0.1-0.11% of the goods, the percussion value can be increased to 9-9 level, and holding capacity and low temperature resistance.

When PVB products have serious adhesion problems (percussion value of 2), add 0.12-0.13% of the product, you can increase the percussion value to 9-9 level, and holding capacity and low temperature resistance.

5, the use of methods and dosage

PVB raw materials in the mix, the PVB bond strength modifier evenly poured pour PVB material, stirring for about 10 minutes, so uniform.

Addition amount is 0.1-0.12%. The maximum amount of added control at 0.13%.

Matters needing attention: 1, because of incompatibility with the plasticizer, can be added before the addition of plasticizer, should not be added at the same time, so as not to affect the mixing evenly.

                                           2, add, pay attention to accurate weighing.

                                           3, the actual use, please do a small test.

6, storage and validity
