Silicone compound containing amino group KH-610

Physical and chemical properties:

Appearance: yellow to brown liquid

Purity %: ≥97.0

Solubility: soluble in organic solvents such as toluene, ethanol, ether, acetone, etc., soluble in water, and hydrolyzed and condensed to produce an oily liquid after being placed.

Features and benefits:

a. Good water stability

b. Extend the shelf life of compound products

c. Enhance adhesion and maintain elongation in an elastic system

d. In the application of foundry industry, increase the strength of molding sand,

e. In the casting industry, it is easy to use, high in strength, and low in cost.

Such as furan and phenolic resin, it does not need to be added afterwards, but can be directly added to the resin during the production process.The strength of the same dosage is even better than that of conventional silanes KH-550, KH-602, and the cost is about 30% of them , At the same time, it can be stored for a long time without reducing the strength.

Comparison with the application experiment of KH-602

Coupling agent	aging	Molding sand tensile strength MPa
		1hour	3hours	24hours
KH-610	1 day	0.52	1.04	1.25
KH-602		0.35	0.93	1.02
KH-610	10 days	0.48	0.87	1.21
KH-602		0.42	0.74	1.01
KH-610	20 days	0.48	0.83	1.23
KH-602		0.33	0.73	0.81
KH-610	60 days	0.32	0.93	1.17
KH-602		0.14	0.35	0.46

The data in the table proves that KH-610 is used in resin sand, whether it is molding sand strength or resin storage stability, it is better than the commonly used silane coupling agents KH-602, KH-550

Application: 

1) Foundry industry

Adding KH-610 to furan resin can strengthen furan resin, increase the adhesion between resin and sand, and thus improve the strength of resin sand. KP-550 is added to furan resin to improve the strength of the resin for about 15 days, while KH-602 is added to the furan resin to improve the strength of the resin for about 3 months, so as to maintain the strength of the furan resin Prolonged. KH-610 has a longer holding time.

RTV greenhouse curing silicone and mixed silane crosslinking sealant

It can improve the adhesion of single and two-component silicone sealants to various substrates including glass, aluminum and concrete. Can enhance adhesion. Without affecting the elongation. The added amount is 0.5-1.0% of the filler.

2) Polysulfide sealant:

When adding single and two-component polysulfide sealants, KH-610 silane coupling agent provides good adhesion to the substrate, including glass, aluminum and steel. The typical dosage of KH-610 silane coupling agent is 0.5-1.0% by weight of sealant. It can be well dispersed in the sealant, which can achieve the internal destruction of the resin rather than the destruction of the interface adhesive layer between the sealant and the substrate.

3) Plastic melt sealant

Using KH-610 to replace the polyamide adhesion promoter in the plastic solution sealant can improve the adhesion to the metal substrate and increase the strength. The silane modified ones have better overall system performance than those with polyamide systems. And the modification is blocked until the system is light in color, and no bubbles will be generated after curing.
